Remedy Sodaly Grapefruit is a prebiotic soft drink from Australian maker Remedy Kombucha, built around apple cider vinegar for its gut-friendly prebiotic content. It uses all-natural fruit flavours, with grapefruit at the centre. The taste is tart, tangy and sharp, with a juicy citrus character and a bittersweet grapefruit twist. This is an alcohol-free option for anyone after something fruity and sharp rather than sweet.
