Alcohol-free beverage Fentimans - If Premium Tonic Water is one of the essential references in the mixology world, it is partly because of the complexity of its preparation. First, the sugars originating from plants are infused in a brewing process before being fermented. Then, macerated plants (cambava and juniper leaves) and lemon grass extract is added to the mix. These are all steps that give this tonic its unique flavour where the freshness of the citrus fruit is softened by a touch of quinine. Whether consumed without alcohol in lemonade or in a cocktail, it is ideal for awakening the taste buds!
