Cocktail recipes specify ingredients and chilling technique, but they typically don’t tell you squat about the ideal amount of water added when you stir or shake with ice. Do drinks have an ideal dilution? We figured with the right people in the room we could probably find some consensus. We were wrong.
But let’s back up:
Dave decided to test dilution values of two drinks â€“ the Sidecar and the Peguâ€“ by doing blind tastings spanning a range of 15-30% ABV (alcohol by volume). Dave and I served 32 consecutive shot-sized glasses of each drink, and got some of NYC’s bartending gods completely sloshed at 3 oâ€™clock in the afternoon. The panel included: Kenta Goto, of Pegu Club; Don Lee, PDT, Momofuku Ssam; Chad Solomon, Milk and Honey, Pegu, Flatiron Lounge, Little Branch; Christy Pope of Cuff and Buttons; Scott Teague of Pegu Club and Meehan, and Eben Klemm, head of beverage for the B. R. Guest Restaurant Empire, and head of the Tales of The Cocktail Shaking Seminar.
First up, the Sidecar: cognac, cointreau and lemon.
We didÂ five sets of four dilutions, in random order at the same temperature (a fairly tepid 0Â°C.) The mix came in at 30.8%ABV.Â WeÂ acheivedÂ our range ofÂ ABV’sÂ with a waterÂ dilution like this:
Set One: 15, 16, 17 and 18% ABV.Â 15%Â ratedÂ first or second with the majority of the tasters, and18% followed as most everyone’s second choice. 16 and 17%Â rated lower; half the panelÂ noted that they wereÂ too sour and acidic. Weird.
Set Two:Â Â higherÂ ABV’s: 23, 24, 25 and aÂ whopping 31%. The 24 and 25% tied as favorites for the round, and the panelÂ agreed that 31% was too boozy, 23% too light.
Set Three:Â 19, 20, 21 and 22%. Results were all over the board.Â Â One bartender said 19% was too acidic and rated it lowest; another said it was the ideal sour and rated it tops. Two thought 20% was well-balanced, and three thought it was far too overdiluted. Most everyone agreed that 21% was the sweetest and was headed in the right direction.
Set Four: 16, 19, 20 and 22%. No clear winner. 16, 19Â and 22% got two top votes each.Â Â 20%Â was ratedÂ either second or thirdÂ by everyone.Â No one thought 16%Â was overlyÂ acidic (as theyÂ did in Set One.)
Set Five: 16, 17, 21 and 22%.Â 21% was votedÂ Â first or second favorite by all. 16% was surprisinglyÂ stillÂ a favorite by halfÂ theÂ group. 17% ranked third across the board, and 24% was agreed to be too boozy and dark.
What did we learn aboutÂ perfecting theÂ Sidecar? Not much.Â We learned that you can’t isolate alcohol dilution like we thought we could; the variables of acidity and sugar balance really complicate things.Â We alsoÂ saw that tasters’ impressionsÂ of a drink are significantlyÂ affected byÂ theÂ otherÂ drinksÂ they areÂ tasting next to it.
Would we fare any better with the Pegu? The recipe: gin, Cointreau, lime, Angostura, Orange bitters.Â The straight mix came in at 35 abv.Â Here is the dilution table:
Set One:Â 15, 16, 17 and 18%. 15% was tops with four of the six bartenders, “well balanced” and “strong”Â Â (strong in quality, not liquor). Â 16% was first pickÂ of the remaining two. The losers were 17%, deemed “soft” and “light,”Â and 18% –Â “sour,” “sharp” and “weak.”
Set Two:Â 16, 18, 19 and 20%.Â Â Â 19% was picked first or second favorite by the group, “nice sugar,” “softest” and “best diluted.” Â 20% was second runner-up.Â 18% was least favored, “sharp” and “bittery.”
Set Three: Everyone was pretty sauced, but we pushed ahead with an even stronger set of 22, 23, and 24%.Â Â No clear favorite.
Set Four: thankfully, our last. 15, 16 an 17%.Â Kenta bowed out toÂ go toÂ work, so we were down to five bartenders.Â Â The outcome seemed random;Â Â everyone had a different opinion. Â Two said 15% was far too strong, one said it was the most balanced. Â One said 17% was the lightest while two claimed it was the most acceptable. 16% was evenly split, too strong for some, and too diluted for others.
After all this: no clear answer on our panel’s preferred dilution. We were shocked by the utter lack of consensus. Each set determined the limits ofÂ perceived dilution and liquor and/or acid balance.Â WeÂ must have structured theÂ tasting poorly;Â arguments erupted over whether the inclusion of bitters had mucked everything up, whether the drink choices had been appropriate, whether we could taste accurately at 0Â°C.Â Â Hard to tell from the raw data, butÂ we suspectÂ that acid and alcoholÂ can come in and out of balance at different dilutions.Â We vowed to re-convene and taste two drinks with lime and sugar, one rum, one gin, then taste straight gin dilutions and straight limeade dilutions to try and figure out what the hell’s going on.
