Bartending Guide: Barrel Aged Cocktails
Trends come & go in the bartending world with some sticking around for years whilst others fade into obscurity over time never to be heard from ever again. There is a ‘trend’ in TRENDS though that I’ve noticed over my long career in bartending. The more difficult the new
‘technique’ or ‘idea’ the quicker in disappears from magazine article pages or instagram blogs. One of the trends that saw this treatment is ‘Barrel-Aged Cocktails’ that was pioneered simultaneously by the UK & USA. The US pioneer was none other than Jeffrey Morgenthaler in his original post all the way back to 2010. This sparked a huge global trend in buying small barrels from the USA & barrel aging anything one could find in his liquor cabinet. Just as quickly as it rose the trend quickly died because it faces a lot of issues such as price costs of production, space required in a bar to use & ultimately the flavour itself was unpredictable. In other words just like any technique it required time to learn & skill to use. In the fast paced world of bartending...
So without further ado the original article from Jeffrey Morgethaler that spiked the interest:
This is the post that started it all: the genesis of Barrel Aged Cocktails.
Inspired by a visit last October in London last fall, where Manhattans are aged in glass vessels to sublime and subtle effect, the barrel aged cocktails I’ve been serving at Clyde Common this year are a decidedly American curiosity.
The rub of aging cocktails in a glass bottle is that the whole premise is built upon subtlety, as we know that spirits aged in glass or steel do so at an unremarkable pace. Being from the United States, where – as everyone is aware – bigger equals better, I pondered the following question: what if you could prepare a large batch of a single, spirit-driven cocktail and age it in a used oak barrel?
A hundred some-odd dollars in liquor later, I was nervously pouring a gallon of pre-batched rye Manhattans into a small, used oak cask whose previous contents were a gallon Madeira wine. I plugged the barrel and sat back in anxious anticipation; if the experiment was a success I’d have a delicious cocktail to share at the bar – if it was a failure then I’d be pouring the restaurant’s money down the floor drain.
Over the next several weeks I popped open the barrel to test my little concoction until I stumbled upon the magic mark at five-to-six weeks. And there it was, lying beautifully on the the finish: a soft blend of oak, wine, caramel and char. That first batch sold out in a matter of days and I was left with a compelling need to push the process even further.
Barrels
I’ve been ordering my used whiskey barrels from Tuthilltown Spirits in Gardiner, New York. They sell a three-gallon charred oak barrel that previously held their lovely whiskey, for around only $75.
Now, three gallons of Negroni might not be practical for the home enthusiast, but the average bar or restaurant should be able to afford that sort of quantity quite easily. For those of you trying this at home, try searching the internet for one-gallon charred oak casks (stay away from the fancy lacquered kind meant for display in dens and 1980s wine bars) and be sure to let us know what you find in the comments section below.
We procured a small number of used whiskey casks from the Tuthilltown distillery and proceeded to fill them with a large batch of Negronis; and that’s when the magic of barrel aged cocktails grabbed our attention. After six weeks in the bourbon barrel, our Negroni emerged a rare beauty. The sweet vermouth so slightly oxidized, the color paler and rosier than the original, the mid-palate softly mingled with whiskey, the finish long and lingering with oak tannins. We knew we were on to something unique and immediately made plans to take the cask aging program to the next level.
Negronis are now prepared in five-gallon batches and poured into multiple bourbon barrels. Robert Hess’ ubiquitous Trident cocktail is currently resting inside single-malt barrels. The El Presidente (à la Matt Robold), Deshlers, Remember the Maines, they’re all receiving the oaked treatment in a little storage room in the basement of the restaurant that I refer to as my “office”.
Once the cocktail is aged long enough for my taste, I then drain the bottle, straining out any charred bits of wood, and bottle the contents for use by my bartenders. To order, the cocktail is then measured out and poured over ice in a mixing glass, stirred, strained into a cocktail glass, and then garnished with the appropriate garnish. It’s quick and simple, as all of the real work has already been done by the barrel.
Anyway, on to the recipes. As simple as it seems to do, I figured not everyone is going to want to do the math to get started on some of these recipes, so here are a few I’ve figured out:
Negroni
Makes Three Gallons
128 oz (approximately five 750ml bottles) dry gin
128 oz sweet vermouth
128 oz Campari
Stir ingredients together (without ice) and pour into a three-gallon oak barrel. Let rest for five to seven weeks and pour into glass bottles until ready to serve.
Manhattan
Makes Three Gallons
256 oz (approximately ten 750ml bottles) rye whiskey
128 oz (approximately five 750ml bottles) sweet vermouth
7 oz Angostura bitters
Stir ingredients together (without ice) and pour into a three-gallon oak barrel (I prefer a barrel that has previously stored sherry, Madeira, or port wine). Let rest for five to seven weeks and pour into glass bottles until ready to serve.
Trident
Makes Three Gallons
128 oz (approximately five 750ml bottles) aquavit
128 oz dry sherry
128 oz Cynar
7 oz peach bitters
Stir ingredients together (without ice) and pour into a three-gallon oak barrel (I prefer a used single malt barrel). Let rest for five to seven weeks and pour into glass bottles until ready to serve.
