Aged Negronis

One cocktail trend I've noticed is the act of aging cocktails in some sort of barrel. I first saw barrel-aged negronis on a menu when I was in Portland last fall. I was pretty intrigued by this--what gets aged in the barrel? Is the cocktail mixed and the whole thing aged or was just one ingredient aged (and if so, which one)? What sort of barrel was it aged in? Once I got home, I did some research and found a good entry on the barrel-aged cocktail trend on Jeffrey Morgenthaler's blog. I like the idea of pre-mixing drinks; it certainly makes dishing up drinks at cocktail parties much faster. I love a drink experiment, so I thought about what I wanted to make and how I was going to age it.

I thought about what would benefit from being soaked in a bourbon barrel (or equivalent) for a few weeks, and I pretty much immediately wrote off bourbon-based cocktails. The bourbon's already been aged for years in bourbon barrels, what's the point of aging it a few more weeks? I can see aging a specific ingredient like Campari or sweet vermouth and then mixing it with bourbon, but that's a test for another day. Because my two main spirit bases are bourbon and gin, I decided to focus on a gin drink. Since Morgenthaler did negronis, I figured I start with that, too. Essentially, you can age anything that's all booze, but I wanted to start simple and focus on a drink that I'm already very familiar with.

Now, I had to decide what I was going to age it in. There are multiple places online to get mini barrels, but that seemed like a lot of booze when I had no idea if this was going to be drinkable or not. One of the places that sells mini barrels, Tuthilltown Spirits, also sells kits that have a 375ml glass bottle along with a wood stick from a barrel. These sticks use something Tuthilltown calls "honey comb" cutouts; the sticks have many little holes drilled at all angles to provide for more surface area. The price on one of these kits is low ($12.50) and it requires a lot less booze, so I went with this.

At some point in my research I came across this blog entry from ManMade. This guy was doing exactly what I wanted to, so I used this as a model. I ordered a bag of Jack Daniel's Wood Smoking Chips from Amazon as an alternative to the barrel staves from Tuthilltown (I used 12 grams of chips so it would be nearly the same weight as the stave) and went to work mixing my batches of negronis.

The recipe I used was a basic negroni mix, but because I was making two batches that were 375ml, I upped the size of my batch. Each bottle had:

• 1/2 cup Plymouth gin
• 1/2 cup Campari
• 1/2 cup Carpano Antica sweet vermouth

Pre-aging

I put these both in the root cellar (a dark, cool place) for two weeks. I shook them up every three or four days. After two weeks, I opened them up, strained each into its own pitcher, and invited folks over for taste tests. I also made a pitcher of "fresh" negronis as a base line. Right away I could see that the aged batches were much darker in color than the fresh. I thought that might tip everyone off to which was the fresh, but it didn't. I labeled each pitcher A, B, or C so it was a blind taste test. To really nerd out, I made up a questionnaire to capture what people thought as they tasted each sample. If I was going to do this again, I'd probably give everyone all three samples at once so they compare each against each other.

The samples have been consumed...now to score these!

Sample A was the wood chip version, B was the fresh, and C was the barrel stave version. I added an small orange peel garnish to each. Most people thought the wood chip version was the most bitter and they generally liked the barrel stave version the most. Personally, I thought A was pretty smooth, not overly smoky, and quite sweet. No one else really agreed with this opinion, but maybe I was biased because I was hoping the best would be the one with the cheapest barrel ingredient. Anyway, the two smoked versions were really very different from the fresh and from each other. I would definitely make either version again as they were both quite tasty.

I plan on aging other cocktails in the future--so far I've thought about the Bijou (gin, sweet vermouth, green Chartreuse, and orange bitters), the Martinez (Old Tom gin, sweet vermouth, maraschino, and bitters), and the Dubonnet Cocktail (gin and Dubonnet). Dear readers, have any of you jumped on this trend? Post in the comments what you've aged and how you've aged it.
