Bittered Sparkling Water

Pre-mixed canned sparkling-water-and-cocktail-bitters apéritif — unsweetened (or barely sweetened) carbonated water dosed with aromatic or gentian bitters, typically 0-10 calories, intended as a low-ABV or zero-ABV stand-in for the classic 'bitters and soda' bar order. Distinct from plain club soda (no bittering aromatics) and from tonic (no quinine). Used as a non-alcoholic apéritif and as a light cocktail base.
