Fever Tree Grapefruit Tonic Water

Fever-Tree's Grapefruit Tonic Water is a flavored tonic mixer. It takes the bitter-citrus structure of classic tonic and tilts it toward grapefruit, so it works as more than a neutral carbonated base. Expect a tonic's dry, faintly bitter backbone with a pithy, tart citrus note up front rather than a sweet juice character. Drinks built on it tend to taste drier and more grown-up than ones made with standard soda or sweetened grapefruit sodas. It is not meant to be sipped on its own, and it does its best work in simple two-ingredient drinks where nothing masks it. Gin is the obvious partner. A London dry with a juniper-forward profile gets a brighter, citrus-led gin and tonic, while a softer contemporary or citrus-driven gin leans into the grapefruit. Blanco tequila is just as good a match, and the combination makes an easy Paloma-style highball with a lime wedge. Vodka also works if you want a cleaner, lighter drink that lets the mixer carry the flavor. A common starting ratio is one part spirit to roughly three parts tonic, adjusted to taste. Serve it well chilled, and chill the bottle or can beforehand so less ice has to melt to bring the drink down to temperature. Pour gently down the side of the glass or along a bar spoon to keep the carbonation intact, and avoid stirring more than once or twice. A tall highball or Collins glass filled with plenty of large, solid ice keeps dilution slow. A large stemmed balloon glass is a good alternative for gin serves, since it concentrates aroma. A wedge or peel of grapefruit is the natural garnish, and a sprig of rosemary or thyme suits gin versions. For food, the bitterness and acidity of a drink like this pair well with salty or fatty dishes. Think grilled prawns, ceviche, olives, or a soft cheese board.
