Cocktails, like definitions, evolve. Early attempts to define the parameters of a cocktail led to a simple - oversimplified, really - list of components: spirits, water, bitters, and sugar. The role of spirits is obvious, and its contrasting twin is water for dilution. Bitters counteract sweetness. The two pairs in proper proportion achieve balance. Missing from that list – sort of – is acid.
Understanding Balance in Cocktails
We need to first acknowledge that American palates are shaped by sugar from an early age. This “Coca-Cola effect” has conditioned many consumers to prefer beverages, including cocktails, that are out of balance in favor of sweetness. This effect shows up regularly at cocktail competitions where professional judges will give the nod to the most balanced/creative cocktail, while the “people’s choice” tends to go toward the sweetest cocktail short of cloying in the competition.
The task of professional bartenders is to help their customers appreciate balance. But for home bartenders, it’s your own palate or your dinner party guest’s tastes that matter. Balance is important because it tends to hit the center of the palate, metaphorically speaking, meaning more of your guests will be happier with a balanced cocktail, and hopefully, you too are in pursuit of balance.
One of the surest ways to add vitality, brightness, and pop – keys to balance – to a cocktail is by adding citric acid; the most useful examples for home bartenders are lemon juice and lime juice. While both add a touch of sugar, they mainly provide a burst of acid that lifts the cocktail’s aromatics and impact on the palate and can help round out the rough edges of the other components.
Why Lemon and Lime Juice Work in Cocktails
Both have roughly five times the citric load of orange juice, which, while delicious, primarily provides sweetness. Oddly enough, lemon and lime are harder to detect in a cocktail than orange juice. Orange juice is so flavorful that it tends to assert itself, as does grapefruit juice, which also tends to add a bitter, astringent note – desirable at times but not great for balance. Lemon and lime aren’t exactly neutral flavors, but at ¼ ounces per cocktail, the overall effect is a bump in acid, not a noticeable fruit flavor.
Some recipes call for additional citrus, especially when fruit is the point. The classic Daiquiri relies on an ounce of fresh lime juice, but the lime is supposed to come through on the palate, and it’s so much citric acid that the recipe needs a half ounce or more of simple syrup to counteract the acidity. To achieve balance, though, most recipes only need a quarter ounce of fresh lime or lemon juice. So how do you choose lime or lemon when making a cocktail? Lime tends to have less sugar and more malic acid than lemon, which makes it the champion for balance.
The malic acid provides additional tartness – a pucker effect – but also carries the zippiness across the entire palate. Lemon juice lacks the oomph to reach the mid-palate, so that the cocktail might finish flat or flabby (not enough acid or too much sugar, respectively).
You’ll find that many give new bartenders the advice that aged spirits like whiskey pair better with lemon, while white spirits like gin pair with lime. While that is a great starting point, it doesn’t hold true for cocktails like a margarita made with an aged tequila. The point is don’t be afraid to experiment and find what fits your palate.
For more adventurous bartenders, yuzu is the new acid of the moment. A citrus fruit primarily associated with Japan (although it originated in China), yuzu offers a burst of citric and malic acids similar to lime, but it has a more noticeable aromatic component that combines fruit, herbs, and flowers. It can add layers of aromatic complexity to a cocktail, but it’s not a natural fit as a substitute for lime.
Classic Gimlet
One cocktail that’s excellent for playing with the effects of different citrus is the classic gimlet. Gin or vodka is fine, but you’ll want dry gin or a very clean vodka.
2 oz. Aviation Gin
¾ oz. Simple syrup
¾ oz. Fresh lime juice
Add the ingredients to a cocktail shaker with ice. Shake and strain into a coupe glass. Garnish with a lime wheel.
Simple. Delicious. Bracing. This cocktail is one of the best ways to show off fresh juice, so you can make variations with lemon, yuzu, grapefruit, mandarins, or any other citrus you can find.
In Closing
Playing with proportions can help you sort out what your palate perceives as a balance between sugar and acid, and spirits and water. For an excellent example of how lime works with another citrus, check out this Classic Paloma recipe.
