Why Tonic Water Pairs So Well With Gin

Tonic water has earned its spot as the ideal mixer for a slew of classic libations. It lends drinks a sophisticated foundation of bittersweetness and a lively, effervescent fizz, making it different from seltzer and club soda. This complexity means it pairs well with a slew of classic flavors, but a herbaceous pour of gin is the traditional go-to. What exactly is it about tonic water that pairs so well with this spirit? To get some insight, we sat down for an exclusive chat with Deena Sayers, the beverage director at The Stand, a comedy club and restaurant in New York City. 

Sayers says tonic water's characteristic bitterness makes it a great pairing for gin's bold, citrus-forward flavors. "It stands up well to gin's complex botanic profile, preventing it from being overly sweet. It plays many roles in the overall balance — the carbonation offers a refreshing lift and subtle sweetness enhances it," she said. While this pairing tastes best cold, its flavors mesh well no matter the temperature, and you can even serve gin and tonic hot for a winter cocktail.

Not only does tonic water balance gin's bitter intensity with sweetness and fizz, it can do the same for other citrus additions like Campari, Aperol, lemon, or lime juice. While tonic water is traditional, Sayers encourages people to try mixing gin with other additions beyond the classic. "Other mixers that I would recommend includes dry vermouth, elderflower tonic or liqueur with a squeeze of lime."

If you're tired of a traditional gin and tonic, Deena Sayers has other suggestions for you to try. Start by adding some vermouth into the mix. This fortified wine offers bittersweet flavors of its own that will mesh well with gin and tonic water, as well as the subtle notes of an orange peel garnish, so it's a nice variation of a classic drink that doesn't stray too far from familiar territory. Choose either a dry vermouth or a sweeter rendition (adding a red or pink vermouth will also bring a nice pop of color). 

Elderflower tonic water is another great pairing for gin. This elevated take on the classic further enhances the citrus undertones of the spirit with its hints of grapefruit and floral aromatics. Finally, consider adding unique liqueurs, such as how José Andrés uses mastiha, a Greek digestif made from tree resin, in his gin and tonic-inspired cocktail. 

While these options are all fair complements for gin, Sayers stresses the importance of staying true to your individual preferences. "Ultimately, the best pairings depend on the specific gin and the desired flavor profile." In short, don't be afraid to experiment. When in doubt, you can always go back to the classic: a vivacious infusion of gin and tonic water with a twist of lime to pair.
