Praise for Cocktails on Tap:

“Jacob Grier was at the forefront of the beer cocktail renaissance before many of us had ever contemplated the idea of a beer cocktail. His vast knowledge of beer and passionate dedication to this area of mixology is certain to push the craft of cocktails forward in a positive new direction.”
–Jeffrey Morgenthaler, author of The Bar Book

“Jacob Grier is a masterful guide through the wickedly creative terrain of beer cocktails, offering not just delightful recipes, but history and cultural commentary, too. Connoisseurs and neophytes alike will find much to savor, and the latter will appreciate Jacob’s tutelage in cocktail basics. Grab a copy and start mixing!”
— Maureen Ogle, author of Ambitious Brew: The Story of American Beer

“As affable and inquisitive as its creator, the book ping-pongs from arcane, centuries-old recipes like eggnoggy curdled-cream-and-ale possets to contemporary beer cocktails gathered from bar pros around the country. A Breakside Brewery IPA, for instance, lends froth and bitter tang to a tiki classic or cuts the cachaça sweetness of a Brazilian “Caip-beer-ihna,” while Mexican lager branches out from the michelada to mingle with serrano-infused mescal and pineapple shrub. The takeaway is clear: it’s time to liberate beer from its bottle.”
— Kelly Clarke, Portland Monthly

Beer cocktails finally legal in Virginia

My former home of Virginia is known for its archaic, overly strict alcohol laws, but there is some good news from the Old Dominion: Beer cocktails are finally legal. Well, some of them anyway:

Virginia law allows restaurants to mix spirits with beer or wine “pursuant to a patron’s” order, meaning that individual cocktails prepared for a customer are perfectly legal. Storing drinks that mix spirits with wine or beer remains illegal, however, unless that mixture can be passed off as sangria (defined vaguely by the mixologists in the state legislature as containing “brandy, triple sec, or other similar spirits”).

Most of the drinks I write about would therefore be legal in Virginia, but there’s a long tradition of batched beer punches that the state’s bars are still forbidden from serving. Ale Punch, a recipe from the great nineteenth century American bartender Jerry Thomas, or Blow My Skull, the favorite of an eccentric Tasmanian governor known for drinking his subordinates under the table, would both fall afoul of the rules. So too would “Beer Nog,” a contemporary take on egg nog that adds porter to the usual mix of brandy, eggs, and cream. And if any Virginians want to go wassailing in the winter, they’ll have to settle for low-proof versions of the beverage that do not fortify the warm ale with stronger spirits.

That’s good news for my book Cocktails on Tap. Read the rest of my article at Reason for a look at more of the country’s liquor laws, and also check out fellow Portland writer Niki Ganong’s new book The Field Guide to Drinking in America, which breaks them down state by state.

Imperial Old Fashioned

Imperial Old Fashioned

The Craft Brewers Conference is taking place in Portland this week, so the city is overrun with brewers and more great beer events than anyone could possibly attend. We were lucky to host one of these at The Multnomah Whiskey Library with Widmer Brewing, who asked us to come up with a few cocktails using their beers.

This Imperial Old Fashioned is my favorite of the ones Michael Lorberbaum and I came up with for the evening. It’s a bit over the top with Clear Creek’s peated single malt whiskey and a 2-inch, crystal clear ice cube laser-etched with the Widmer logo. To sweeten it, we made a syrup with cane sugar and Widmer’s KBG Russian Imperial Stout, which has dark, roasted malt notes that complement the smokiness of the whiskey. (For a similar idea using genever and rauchbier, see Katie Stipe’s Vandaag Gin Cocktail in Cocktails on Tap).

2 oz Clear Creek McCarthy’s Single Malt Whiskey
1 barspoon Imperial Russian Stout syrup
1 dash Angostura bitters
1 dash Bittered Sling Malagasy chocolate bitters
grapefruit peel, for garnish

Stir over ice and pour into a rocks glass with a big ice cube (laser etching optional). Garnish with the grapefruit peel.

For the stout syrup:

1 22 oz bottle KGB Russian Imperial Stout
44 oz cane sugar

Combine in a pan and stir over low to medium heat until the sugar is dissolved, taking care that it doesn’t spill over. Let cool and skim any foam, then bottle and refrigerate. You should feel free to scale down the recipe and drink the remaining beer.

Hangman’s Bier

One of the frustrations of writing a cocktail book, rather than a continuously updated blog, is the long interval between writing and publication. In the time between sending the book to the printer and seeing it arrive on store shelves, you’re bound to come across drinks you wish you’d been able to include. And with Cocktails on Tap coming out tomorrow, I’m sure this process will only accelerate as I hear from bartenders and cocktails enthusiasts about their favorite beer cocktails.

This post is devoted to one of these that I’d love to go back in time and slip into the manuscript. My friend and colleague at the Multnomah Whiskey Library, Jordan Felix, introduced me to it, and it was a popular cocktail on the menu there this winter.

The “Hangman’s Blood” is a cocktail that reportedly first appeared in Richard Hughes’ 1929 novel A High Wind in Jamaica. From Wikipedia:

Hangman’s blood… is compounded of rum, gin, brandy, and porter… Innocent (merely beery) as it looks, refreshing as it tastes, it has the property of increasing rather than allaying thirst, and so once it has made a breach, soon demolishes the whole fort.

In the 1960s, novelist Antony Burgess offered an even more potent recipe to The Guardian:

Into a pint glass doubles of the following are poured: gin, whisky, rum, port, and brandy. A small bottle of stout is added, and the whole topped up with champagne or champagne surrogate. It tastes very smooth, induces a somehow metaphysical elation, and rarely leaves a hangover… I recommend this for a quick, though expensive, lift.

“This is a highly dangerous mixture and consumption is not advised,” warns The Burgess Foundation, who “takes no responsibility for illness or injury caused by following this or any other recipe by Anthony Burgess.” A fair warning.

Let’s be honest. Both of these drinks sound abominable. But part of the fun of exploring old cocktail recipes, especially those with a literary pedigree, is reviving them with better balance. Jordan’s Hangman’s Bier is a much simplified take on the drink, with lime and demerara standing in for funky Jamaican rum, and this version is a lot less likely to leave the imbiber awakening the next morning feeling like he’s been worked over by a gang of droogs.

1 1/2 oz rye whiskey (Wild Turkey 101)
1/4 oz rich demerara syrup (2:1)
1/4 oz lime juice
4-5 oz porter or stout
nutmeg, for garnish

Pour the whiskey, lime juice, and demerara syrup into a collins glass and stir to combine. Add ice and top with the beer. Stir gently and garnish with freshly grated nutmeg.

Cocktails on Tap goes on sale everywhere on March 24. I’ll be doing a signing at Powell’s tonight, March 23, at 7:30 pm, followed by a party at the Multonomah Whiskey Library. Both events are open to the public.

Cocktails on Tap release parties in Portland

My beer cocktail book, Cocktails on Tap, is now just a couple weeks away from publication. We’ve arranged a couple of fun events in Portland as we approach the official release.

March 17 — Is there a better holiday to celebrate a book of beer cocktails than St. Patrick’s? On March 17th, my friends at the Bull in China bar shop are hosting an informal toast to the book. We’ll be serving complimentary glasses of Abbey Street Punch, a recipe contributed by Erick Castro of Polite Provisions in San Diego. We’ll also have a very limited number of books available for pre-release sale, and Bull in China is offering special deals on their fantastic new mixing glasses too. Check out their recommendations in the new issue of Portland Monthly.

Featured in the punch will be Teeling Irish Whiskey and Deschutes Black Butte Porter, complemented by a blend of Jamaican rums, lemon juice, sugar, allspice dram, soda, and nutmeg. It’s a great punch, and a favorite of friends who tested the recipe at parties. We’ll also have Teeling an Deschutes on hand for when the punch bowl runs dry.

March 23 — On March 23 we’ll be hosting our big release party at two of my favorite places in Portland. The evening will begin at the iconic Powell’s bookstore on Burnside, where we’ll be hosting a signing starting at 7:30 pm. Then at 9 pm we’ll walk over to the Multnomah Whiskey Library, where they’re generously opening the doors and offering a special menu of beer cocktails and punches from the book.

I look forward to seeing readers at all three events. For those of you not in Portland, stay tuned for book signings and cocktail parties in additional cities and pre-order your copy now.

Hot take on beer

Today at The Atlantic, I have a literal “hot take” on beer:

If there’s one thing big beer marketers know, it’s that people like their beer cold. “It’s a simple fact that consumers love ice-cold beer, and we love providing it,” writes MillerCoors, touting their cold-activated labels with mountains that turn blue to indicate when beer “goes from cold … to Super Cold.” The problem of insufficiently frigid beer apparently plagues the American consumer and technology is here to help.

But since this is the middle of winter, consider an alternative suggestion. Why not drink hot beer?

Read the whole thing. If you find the drinks in the article intriguing, you should of course pre-order my book. There’s an entire chapter on these “Hot Helpers” with recipes for recreating them with modern ingredients.

The Second-Best Amaretto Sour in the World

Aquavit Week is over, but the aquavit cocktail blogging continues!

When planning the menu for our Nordic Night dinner at Fenrir, I had one spot left to fill in which I knew I wanted to feature the Krogstad Gamle aquavit. I tried out a bunch of ideas, but none of them were coming together quite right. Worse yet, I was running out of aquavit. I needed an idea soon!

As I often do in such situations, I turned to The Flavor Bible, an indispensable guide to flavor pairings that work. Reading the pairings for the strong anise note in Krogstad, nutty flavors kept coming up. That got me thinking about amaretto, which got me thinking about The Best Amaretto Sour in the World™.

That drink comes from my fellow Portland bartender Jeffrey Morgenthaler, who combines amaretto with cask-proof bourbon. It’s an awesome cocktail. With a few adjustments, could it work with a barrel aged aquavit? The answer was yes, the drink worked on the first try, and I didn’t have to devote any more of the non-existent Aquavit Week budget to yet another purchase. In a nod to Jeff, our Nordic Night humbly offered The Second-Best Amaretto Sour in the World.

1 oz Krogstad Gamle aquavit
1 oz amaretto liqueur
1 oz lemon juice
1 teaspoon rich simple syrup
1/2 egg white
lemon twist, cherry, or star anise for garnish

Combine all ingredients in a shaker and give it a dry shake to aerate. Add ice and shake again. Strain into an ice-filled rocks glass and garnish.

Below is the full menu from our Nordic Night, and here is a review from Portland Mercury restaurant critic Andrea Damewood, who happened to be in attendance that evening.

Books about drinks for Christmas

As we approach the end of 2014, I have a stack of cocktail books awaiting review building up on my coffee table. This has been a better for year for books about drinking than any I can recall since I started writing about cocktails. A lot of these would make great last minute gifts for the drink lovers in your life. Of course one could also buy your friends my own book — waiting for its March 2015 release date will only add to their anticipation! — but impatient drinkers will also find joy in receiving the books below.

The Bar Book: Elements of Cocktail Technique, Jeffrey Morgenthaler with Martha Holmberg– Jeff’s new book has instantly become the top book I recommend to people wanting to learn about cocktails. There aren’t many recipes here, although the ones that do appear are very good. Instead the focus is on techniques, topics like stirring, shaking, juicing, making syrups, incorporating dairy products, and making high quality ice. Jeff goes into the reasons to do things in certain ways, busting bartender myths as he goes. Although the advice is drawn from working in a professional environment, it’s also very useful to know for any home bartender who wants to elevate their drink making. If you enjoy mixing cocktails, this book needs to be in your library.

Shrubs: An Old-Fashioned Drink for Modern Times, Michael Dietsch — Michael Dietsch has his work cut out for him with this book. The first question potential readers will likely ask about shrubs is, “What are they?” When they find out that shrubs are infused, sweetened vinegars that you’re supposed to drink, I suspect their second question is, “Why?” But as craft bartenders have recently rediscovered, and as a few communities have known for years, shrubs are delicious. They’re a great way to preserve seasonal fruit and make easy, tasty drinks mixed with soda water or cocktails.

Dietsch’s book is sure to be the definitive source on the topic. It’s so new in my pile that I haven’t had a chance to try out the recipes yet, but the flavor combinations sound very good. His exploration of the history of using vinegar in drinks is interesting too. And though shrubs work great in cocktails, and Michael does include a chapter of cocktail recipes, this isn’t just a book for people who drink alcohol. Anyone who abstains in the long or short-term, but doesn’t want to give up imbibing drinks with complex flavors, would get a lot out of this book.

Proof: The Science of Booze, Adam Rogers — Wired editor Adam Rogers’ Proof is a good popular science book all about alcohol, tracing its journey from the yeasts that ferment it to the hangovers that all too often follow on the heels of its consumption. Mostly non-technical and an enjoyable read.

Liquid Intelligence: The Art and Science of the Perfect Cocktail, Dave Arnold — Even before this book came out, Dave Arnold was having a positive influence in my bars and kitchen. His technique for clarifying citrus juice with agar agar is one I picked up right away and incorporated into cocktail menus, and his Searzall culinary torch has been a welcome addition to my sous vide set up at home. Though I haven’t yet made it to his bar Booker and Dax in New York, it’s safe to say that I’m a fan.

In Liquid Intelligence, Arnold dives deep into the science of making cocktails better. Sometimes this requires tools beyond the reach of most bartenders, such as rotary evaporators or centrifuges, but he also makes an effort to make recipes replicable at home. Ultimately, though, I think I’ll be turning to this more for reference and inspiration than as a recipe book. There’s a lot to digest here and I’m only partially through it after skipping to some especially interesting parts. Highly recommended for the working pro or home enthusiast who wants to gain a much better understanding of how drinks work and how to use that knowledge to make them better.

Honorable mentions: The 12 Bottle Bar, which I wrote about earlier this year, would also make a great gift. Drink books from 2014 that I’ve not yet read, but that are on my list, include: Sherry: A Modern Guide by Talia Baiocchi; The Old Fashioned by Robert Simonson; Death and Co. by David Kaplan, Nick Fauchald, and Alex Day; The World Atlas of Coffee by James Hoffmann.

Aquavit Week 2014

My favorite week of the year, Aquavit Week, begins today. What do we have in store for 2014? An opening party tonight at The Hop and Vine, a cocktail pairing dinner at Racion, a “Nordic Night” and Fenrir, and more than twenty Portland restaurants featuring aquavit cocktails. It’s also been a good year for aquavit, with the number of aquavits available in the US also surpassing twenty this year. Get all the information at the Aquavit Week website, and hopefully I’ll see you at one of our events around Portland.

Two new aquavits to try

It’s getting harder for me to keep up with all the new aquavit coming on to the American market, which is a great thing considering how few bottles were available just a few years ago. When I first started writing about aquavit, there were only four producers in the United States. Now there are at least twice that many, with several of them making multiple expressions. Imports from Europe have increased too. Not long ago Linie was the only one left; in the past year at least three additional imports have come ashore. As I make plans for Aquavit Week 2014, here’s a look at two of the new arrivals.

If you’d told me a year ago that there would be aquavit distilled in Montana before it was made anywhere on the East Coast, I would have been skeptical. But to the best of my knowledge, no American distiller east of Illinois has taken up the challenge of making aquavit. Montgomery Distillery in Missoula, Montana has. My friend Paul Willenberg smuggled back a bottle of their Skadi aquavit on a recent business trip and it’s become one of my favorites.

Named after the goddess of “bowhunting, winter, mountains, and justice,” (how’s that for a resume?), Skadi is vapor-infused with caraway, dill, lemon peel, and other botanicals. The caraway is pleasantly assertive. The spirit would probably be good in cocktails, but I’ve already finished too much of my bottle to try it out. This is one to store in the freezer and drink straight. I only have a couple pours left, so I’ll keep my fingers crossed someone I know is headed to Missoula soon.

The most recent aquavit I’ve purchased is Brennivin, a.k.a. the “Black Death” of Iceland. This is the stuff of legend. Anthony Bourdain drank it on “No Reservations.” It shows up in Kill Bill Vol. 2. Dave Grohl says it makes you feel “like you’ve done acid… like you can’t feel your feet.” One of the first media outlets to cover its arrival in the United States was Vice, of all places. Brennivin is metal.

At least it is if you’ve never tried aquavit. At the risk of destroying its image, to me it’s nice and well-balanced. This is another aquavit I’d gladly drink straight from the freezer, and it also works well in a Negroni-type cocktail. It’s good stuff, and really one of the more approachable aquavits I’ve tried. The label is striking, and at about $35 a liter it’s affordable too.

But most people haven’t tried aquavit. And Iceland, especially, has a weird relationship with alcohol. The country was an early adopter of Prohibition. They legalized liquor in 1935, but didn’t get around to allowing beer until 1989. With beer unavailable, one can imagine why unaccustomed visitors might have found this schnapps intense as the plague. If Dave Grohl promising people that they won’t feel their feet is what it takes to popularize aquavit, then I’m all in favor. Drink that Black Death.

Announcing Cocktails on Tap

If it seems like I’ve been writing very little this year, there’s a good reason for that. I’ve actually be writing more than ever, but that effort has been going into my first full-length book. Since 2011 I’ve been kicking around the idea of doing a book on beer cocktails. The road to publication is long and winding, and for a long time it looked like the project was not going to happen. Then in the fall of last year everything finally clicked into place, thanks to the work of my agent Jud Laghi. In December we signed a deal with Stewart, Tabori, and Chang to publish Cocktails on Tap: The Art of Mixing Spirits and Beer.

The upside of being patient is that the book is far better than it would have been had I written it a few years ago. Stewart, Tabori, and Chang makes beautiful books, and my editor there, Laura Dozier, has been supportive the entire way of making this the definitive book on mixing with beer. You can see that commitment to quality in the cover above. And on the inside? Full-color photographs shot by David L. Reamer, whose most recent work includes the Toro Bravo and Le Pigeon cookbooks. A foreword by Stephen Beaumont, co-author of The World Atlas of Beer and The Pocket Beer Guide 2015. A deep dive into the weird history of beer cocktails, the best of my original drinks and collaborations with Ezra Johnson-Greenough and Yetta Vorobik, and contributions from some of the most creative bartenders I know. More than fifty recipes for cocktails and punches made the final cut. I’m sitting in a coffee shop now approving the final color proofs and I couldn’t be happier with how it’s all turned out.

Cocktails on Tap will be released on March 17, but you can pre-order it now. And please do! This book has been in the works for a long time and I can’t wait to get a copy into your hands.

Playing with the Novo Fogo Caipirinha Kit

The Caipirinha — a simple, rustic combination of muddled limes, sugar, and cachaca — is one of the world’s most popular cocktails. It’s also one of the easiest to prepare, tolerant of some imprecision in measurement and requiring no straining whatsoever. Just muddle the limes and sugar, add cachaca and ice, shake, and pour the whole thing into a glass. A basic recipe:

2 oz cachaca (Novo Fogo of course!)
1/2 lime, quartered, trimmed of pith
1 tablespoon superfine sugar

That’s pretty easy. To make it even easier, Novo Fogo Cachaca recently introduced a new Caipirinha Kit containing a bottle of their silver cachaca, a nice wooden muddler, and two mason jars in which to make and serve the cocktails. The jars eliminate the need for even having a cocktail shaker; shake everything in the jar, pop the lid, and drink. It’s so easy, even a pug can do it.

Well, almost.

Since I work with Novo Fogo, they sent me a few of the kits to play around with and try out in some seasonal variations. Another great thing about the Caipirinha is that it’s incredibly versatile. The simple base of sugar, lime, and cachaca lends itself to lots of possibilities, pairing nicely with fresh fruit, herbs, and other spirits. I took the kit out to a few parties to see what we could come up with.

First up was meeting with my friends Tom, Kristen, and Porter the Pug. Taking advantage of end of summer Oregon produce, we hit the backyard with a bunch of berries. A couple combinations that worked: A Caipirinha with huckleberries and basil, and another with blueberries and St. Germain. In both drinks a handful of fruit was muddled along with the lime and sugar, then everything shaken together.

The next stop was a picnic with the Portland Culinary Alliance at Goschie Hop Farms in Silverton, Oregon. This was right at the beginning of fresh hop season, so hops were everywhere. As you can imagine, the place smelled amazing. (Yes, that’s an entire room filled with hops.)

This gave me the idea of making a fresh hop Caipirinha. The Caip-beer-inha, a Caipirinha topped with a splash of IPA, is a cocktail Ezra Johnson-Greenough and I have served many times, so this seemed like it could work. It turns out that muddling hops doesn’t actually extract a ton of flavor, although the drink was nice enough. A fresh hop cone does make a killer garnish though. When they’re in season, I could imagine using them to decorate a Caip-beer-inha.

Finally, at a cocktail fundraiser event at Fish Sauce, Tommy Klus, Will Ray, and I dialed in a Caipirinha made with kummel, a liqueur flavored with caraway and other savory herbs, proving that Caipirinhas really can work with just about anything. This one had cachaca, lime, sugar, kummel, and Angostura bitters, and was surprisingly tasty. (Recipe coming soon; the photo above is our old-style mason jar.)

The Caipirinha Kits are already available in a few states, including Oregon, with many more on the way.

A visit to Diam’s high-tech cork facility

Most of the press trips that wine, spirits, and beer writers are invited on focus on what goes into the bottles we drink. In July, I was invited to Spain for a trip dedicated instead to the part that seals so many of those bottles: cork. Corks are one of those things we tend not to think about until they malfunction by crumbling apart, oxygenating a wine, or introducing “cork taint.” The growing acceptance of screw caps and synthetic corks is partly a response to the challenges of using natural cork. Our host in Spain, Diam, is a company that makes a sort of hybrid technological cork, combining natural cork material with new techniques for removing impurities and increasing consistency. They brought us to their facility in San Vicente de Alcantara to show off the process.

Preparing for this trip, I had romantic visions of the cork forests of Spain and Portugal. These visions were eventually fulfilled on an evening trek into the countryside, as seen in the photos above.

However most of our visit was spent here to learn about Diam’s technological process for transforming bark from cork trees into reliable stoppers that won’t ruin a bottle of wine. This was more industrial than romantic, but it was a fascinating learning experience.

We arrived a little too late in the season to see the local cork harvest, but the photo above (provided by Diam) shows how it’s done. The bark of cork trees is rich in suberin, a rubbery, waxy substance. In nature, the suberin prevents water loss by keeping moisture inside the tree. This same quality makes it great for keeping wine locked inside bottles.

Slaking the world’s thirst for wine requires a lot of cork. (Above: piles of fresh cork bark awaiting processing at Diam; you can barely make out a few people working on top.) Fortunately, harvesting bark doesn’t kill the trees, and after reaching maturity each tree can be harvested about once every decade. Driving through this region of Spain and Portugal, the brightly colored trunks of recently stripped trees stand out along the roadside.

After processing, traditional corks are made by punching through the bark. Obviously punched corks can only be extracted from sufficiently thick bark and much of the material is left behind. This can be put to other uses, including the technological corks made by Diam.

Here my friend Baylen demonstrates his invention of cork knuckles. Not a product offered by Diam — yet.

The Diam process begins by grinding the bark and sorting out the suberin-rich powder, which they call “cork flour,” so that it can eventually be reformed into a cork shape with food safe binders and microspheres. Agglomerated corks have been around in some form for years; it’s the step prior to agglomeration in which things get interesting.

Diam’s biggest innovation is treating this cork flour with supercritical carbon dioxide. In a supercritical state, created under very high pressure, fluids take on properties of liquids and gases. They are able to both permeate a substance and dissolve materials. By fine-tuning pressure and temperature to control its density, supercritical CO2 can be used to extract some substances while leaving others behind. If you drink decaffeineated coffee, there’s a good chance the beans you brew were treated in this way. The CO2 process is one of the main methods used to selectively extract caffeine from green beans.

Diam uses this same process to remove impurities from cork. The most important of these are TCA and TCB, the chemicals associated with cork taint. But lots of other stuff gets removed too, resulting in a cork that is neutral in its potential flavor impact on wine. (Above: quality control testing of corks by infusing them in water.)

A neat advantage of making corks this way is that other characteristics can be controlled too. By varying the elasticity of the corks, Diam can design them for less expensive, short-term aging, or for higher end wines intended to age for years. The box above shows their 1, 3, 5, and 10 year corks; they’ve also recently introduced a cork designed to last for 30 years.

They’re also able to control the permeability of the corks. Corks are naturally permeable, but a cork allowing too much air into a wine can ruin it. On the other hand, depending on the wine, a little bit of oxygenation could be a good thing. These corks come in varying degrees of permeability, allowing wine makers to choose the corks best suited to their wines.

Though conversation about corks tends to revolve mostly around wine, Diam also uses its process to make corks for beer and spirits (photo above courtesy of Diam). The corks for spirits raised an interesting question for me. I’ve rarely come across spirits I’d identify as suffering from cork taint, but on the few occasions I have the off aromas have surpassed anything I’ve come across in wine. Since spirits are much higher in alcohol than wines, and since alcohol is such a good solvent, I’d have thought that TCA would be an even bigger problem for spirits than it is for wine. Yet we rarely hear about spirits being “corked.”

As it turns out, I was half right. Spirits are a more effective solvent. But the team at Diam directed me to a scientific paper evaluating tasters’ ability to detect TCA in cognac, and it turns out the threshold level for perceiving it is much higher. The paper is in French, but in loose translation the tainted spirits had aromas of “mold, mushroom, wet mop, etc.” However the concentrations needed to perceive these notes unambiguously appear to be an order of magnitude larger than for wine. Higher alcohol seems to have a masking effect for the TCA. (I suspect that the tendency to store wine on its side, in contact with cork, and to store spirits standing vertically may also be a factor, but I don’t know for sure.)

One funny aspect of the Diam corks is that, at the insistence of wine makers, they have striations printed on them to mimic natural cork. A casual consumer could pull one out with a corkscrew and never notice the difference. Seeing the unfinished Diam corks come out and then get printed to resemble their purely natural punched cousins reminded me, of all things, of Howard Roark’s critique of the Parthenon in The Fountainhead:

“Look,” said Roark. “The famous flutings on the famous columns — what are they there for? To hide the joints in wood — when columns were made of wood, only these aren’t, they’re marble. The triglyphs, what are they? Wood. Wooden beams, the way they had to be laid when people began to build wooden shacks. Your Greeks took marble and they made copies of their wooden structures out of it, because others had done it that way. Then your masters of the Renaissance came along and made copies in plaster of copies in marble of copies in wood. Now here we are, making copies in steel and concrete of copies in plaster of copies in marble of copies in wood. Why?”

Because wine is tied up with tradition, that’s why. Despite the rise of synthetic stoppers, screw caps, and wine that comes in kegs and boxes, people still want to pull a plug of wood out of a bottle neck, even if that means occasionally dumping a corked bottle down the drain. And for wines that are meant for aging, corks are still one of most proven tools.

Are all these new high-tech corks really necessary? Claims about the rate of cork contamination are controversial. For one thing, cork isn’t the only source of TCA; it can enter wine at other stages of the production process, but the final consumer will declare the wine to be “corked” regardless of whether the cork is the actual source. Other defects, real or imagined, may also be attributed to the cork. (Working for several years in a top wine bar, it wasn’t uncommon to have “corked” wines returned that seemed fine to me. Did customers imagine it or just not like the wines? Am I less sensitive to TCA than other consumers? I suspect it was a little of both.)

Estimates of the rate of cork contamination range from 7% at the very high end to under 1% on the low end. The Cork Quality Council claims that rates have dropped more than 80% in the past decade thanks to improvements in the industry; they have a website, CorkTaint.com, dedicated to rehabilitating cork’s image and promoting studies showing low rates of contamination. Diam, for its part, declined to wed itself to a particular number.

Still, no one likes to open up a special bottle of wine to find that it’s been ruined by a fault that could have been prevented. The market now offers a lot of options varying in price, consistency, and longevity for sealing different wines, all of which have their place. The Diam corks are an interesting addition to that spectrum. I’m not a winemaker, nor do I pretend to possess the expertise to say which closures are best for which wines, but after this visit I certainly wouldn’t mind finding a higher tech cork in the next bottle I open.

12 Bottle Bar comes to Portland

David and Lesley Jacobs Solmonson, authors of the 12 Bottle Bar weblog, have long been two of my favorite cocktail writers. After knowing them online for several years, we finally met in person at the International Association of Culinary Professionals conference in Chicago last March, where we presented a panel together on the history of beer cocktails. And now they’ve turned their blog into a full-length book, The 12 Bottle Bar from Workman Publishing.

The premise of the book is simple: If you’re making drinks at home, you may not want to be like me and have an entire corner of your living room taken up with booze bottles, a kitchen counter covered in bitters, and a refrigerator so full of vermouth and other aperitifs that there’s barely any room for food. You may only want, say, twelve bottles.

The 12 Bottle Bar is their take on which dozen bottles those should be along with creative, engagingly written recipes for cocktails you can make with them. The picks aren’t all obvious. Genever makes the cut but tequila doesn’t. Lesley literally wrote the book on gin and genever a few years ago, and of course I’m glad to see genever getting more appreciation, but that choice will surely drive some conversation. The drinks include contributions from many of their friends in the industry, including a few from me (but don’t let that call their good taste into question).

David and Lesley will be in Portland this Thursday (September 18) to promote the book. At 7:30 they’ll be doing a signing at Powell’s on Hawthorne Avenue. Then around 9:00 we’ll all head down the street to Bazi Bierbrasserie for a few cocktails from the book featuring El Dorado rum and Bols genever. Come buy a copy and join us for a round.

Recent reading, drinks edition

Vodka Distilled: The Modern Mixologist on Vodka and Vodka Cocktails, Tony Abou-Ganim with Elizabeth Faulkner — Vodka is the most popular spirit in the United States, except among fancy mixologists. As craft cocktails have enjoyed a renaissance over the past decade, whiskey, gin, rum, bitter and herbal liqueurs, and other flavorful spirits have found favor with bartenders. Vodka, though in demand from many consumers, often struggles to find a place on the menu.

Vodka doesn’t have much presence in the canon of vintage American cocktails, which is one reason cocktail bars shun the spirit. Whiskey, gin, brandy, rum, and fortified wines abound in vintage books. Vodka arrived late on the scene, not taking off in the United States until enterprising marketers mixed it with ginger beer to create the Moscow Mule, served in frosty copper mugs. This early success set a smart strategy for vodka: Rely on other ingredients to provide flavor and present cocktails in a striking way.

Like many bartenders, I tend to avoid vodka on my own menus. There are a limited number of ounces to work with in a drink and it can seem a waste to use them up on a spirit that is legally defined in the United States as being “without distinctive character, aroma, taste, or color.” With the wealth of other spirits now available, there is almost always something available to complement the other elements of a drink and provide additional layers of complexity: The botanicals of gin or aquavit, the funky notes of rum or cachaca, the oakiness of cognac or whiskey. Why opt for vodka instead?

Thus Tony Abou-Ganim has his work cut out for him Vodka Distilled. Abou-Ganim aims to fix the disconnect between consumers who love vodka and the craft bartenders who often ignore it. With more than three decades in the industry, including landmarks such as Po and the Bellagio, there’s no one better suited to do it.

“The fact that vodka suffers from a misplaced lack of respect was highly motivating for me to write this book,” writes Abou-Ganim in the introduction. He also disputes the popular notion that all vodkas are the same. “Think about tasting and comparing one vodka to another not, not as comparing apples to oranges but akin to comparing apples to apples — apples of the same variety grown in different orchards with differing geography and under various climate and nutrient conditions.” Though subtle, the differences are there.

Following his advice, I pulled out the myriad bottles of vodka I’ve acquired over the years, most of them never opened, and had an impromptu tasting. I tried them first neat at room temperature, then again after chilling in the freezer. It’s been a long time since I put much thought into tasting vodka, and I have to admit that it was a worthwhile experience. Subtle nuances were readily apparent and drinking them chilled was enjoyable.

The most valuable part of the book may be the chapter of vodka cocktail recipes. Regardless of one’s personal preferences, one’s guests (at home or in a bar) are likely to request vodka cocktails from time to time. It’s good to have some drinks up your sleeve. Vodka Distilled provides a good selection. And while I might be tempted to substitute gin in a few of them, they make a tasty collection of classics and a few new creations.

Other sections of the book look at vodka and caviar pairing — currently out of the budget of this reviewer; regulations and definitions; methods of production; and tasting notes on 58 different vodkas. Photographer Tim Turner’s work is elegant. I learned quite a bit from the book, and recommend it.

The Drunken Botanist: The Plants that Create the World’s Great Drinks, Amy Stewart — How much fun can a book that’s essentially an orderly listing of plant facts be? If it’s about how plants are transformed into drinks and it’s written by Amy Stewart, quite a lot. I found myself eagerly consuming The Drunken Botanist — sassafras to sundew to sweet woodruff, to take a random selection — on a long plane trip. It begins with the plants used for fermentation of alcohol, moves on to those used for flavoring during productions, and ends with fresh ingredients added at the last minute in the making of cocktails.

The book includes recipes and tips for gardening, though I’m going to find the most use of it as a very thorough reference (at least until I move into a place more friendly to growing plants). It’s engagingly written and highly informative, easily one of the best drink books to come out last year.

The Audacity of Hops: The History of America’s Craft Beer Revolution, Tom Acitelli — Maureen Ogle, who has been the go-to historian of American beer since the publication of her book Ambitious Brew, endorses Tom Acitelli’s history of modern American craft brewing: “My reign is over. Craft beer has a new historian, and I hereby hand my crown to him (and do so with good cheer).”

It’s a very thorough, well-researched book, and covers both the very early days of brewing at Anchor and New Albion along with recent developments. (Maybe I’m being provincial, but my one complaint is that the Pacific Northwest brewing scene seemed to be a bit neglected.) The history may be too detailed for a casual reader who’s not deeply into beer, but for those who are, this is the book to get.

Bar Jutsu: The American Art of Bar Fighting, James Porco — This book isn’t about drinking, but rather the potentially violent situations that arise when people drink too much. Having spent most of bartending career in genteel spots like The Carlyle and Metrovino, my qualifications for reviewing a book on bar brawls are extremely dubious. I did fence in college though, and took a year of aikido, so my skills may come in handy if a fight ever breaks out while I’m sabering a bottle of champagne.

James Porco, a professional bouncer and certified ninjitsu instructor, is qualified to write one. His book explains basic techniques, with an emphasis on ideally avoiding violent confrontation altogether and on ending it as quickly as possible with strategic grapples when fights do erupt. It’s written in a jokey style, sometimes veering too much into bro territory, with some amusing real life anecdotes involving pickle fights and drunken circus clowns (really). Techniques are broken down with photographs and instructions. You’ll need a partner to practice the maneuvers, and learning from a book is much harder than learning in person, but there seems to be enough detail here to try things out. It’s a fun book with some sound advice that, hopefully, one won’t have many occasions to use.
