Origin & Story

United Kingdom, modern era

St. Germain elderflower liqueur helped establish elderflower as a premium cocktail ingredient, and its pairing with grapefruit — both floral and bittersweet — became a signature combination. The alcohol-free version leans into the bitter citrus, which tonic water amplifies beautifully.
