If your cocktail is 1 part spirit and 3 parts mixer, you don’t need a math degree to see how important the mixer is in that equation. Luckily, Fever-Tree Mixers are carefully crafted to bring out the best in every drink. Cofounders Charles and Tim go to the ends of the earth to find the very best ingredients for their premium mixers, which come in a variety of styles and flavors perfect for any cocktail.

Premium Indian Tonic Water: This award-winning tonic water is made with spring water, botanical oils and the finest quinine sourced from original Cinchona ledgeriana trees in the Democratic Republic of Congo. The quinine adds a gentle bitterness ideal for enjoying with gin.

Refreshingly Light Indian Tonic Water: Offering a lighter taste and fewer calories, this distinctively clean, crisp and refreshing tonic water is made with naturally occurring fruit sugars, spring water and quinine, plus botanical oils like Mexican bitter orange from the Yucatán Peninsula.

Club Soda: Simple yet sophisticated, this silky smooth club soda starts with low-mineral-content spring water and bicarbonate of soda—no quinine required. Its high level of fine carbonation and lack of aroma are sure to highlight any spirit.

Ginger Ale: This full-bodied ginger ale gets its fiery spice from some of the finest gingers in the world: Cochin ginger from India (earthy/chocolaty), Nigerian ginger (intense aromas/depth) and fresh green ginger from the Ivory Coast (zesty lemongrass).

Fun fact: Quinine is a bitter crystalline compound found in the bark of cinchona trees, known colloquially as “fever trees”!
