Fever-Tree Premium Tonic Water is a non-alcoholic mixer produced by Fever-Tree, a brand founded in 2004 by Charles Rolls and Tim Warrillow in the United Kingdom. It is made with quinine sourced from Cinchona Ledgeriana trees in the Democratic Republic of Congo, botanical oils, and spring water, with a touch of Mexican bitter orange for a subtle citrus character. A 4-pack of 200ml bottles typically retails for around $6 to $8.
Light and delicate on its own, this bright, balanced and refreshing tonic's generous citrus zest notes work particularly well with less juniper forward New American gins or with blanco Tequila.
