Each variety in the Gemellii range is made with Italian water from the mountains in Piemonte, sweetened with organic agave for a delicate character and flavoured with extracts from fruits, roots and herbs. Gemellii's Indian Tonic provides a classic, bitter flavour profile, with an aromatic quality from Sicilian lemon oil. Meanwhile, the Blueberry Tonic provides a fruity twist on the traditional mixer, infused with a playful blueberry flavour against a pleasantly bitter backdrop. The Bergamot Tonic layers notes of grapefruit and fennel on a base of  – you guessed it – Italian bergamot. It's our favourite of the bunch, and one we'd happily pair with a herbaceous gin, to complement the tonic’s citrus flavours, and a grapefruit-wheel garnish. Perhaps the most unusual drink In the Gemellii line-up is the Bitter XXVI, which the brand calls ‘an aperitivo without the alcohol’. Ideal for people looking for a soft drink with a grown-up flavour profile, it boasts a satisfying bitterness and complexity from a blend of 26 herbs, and can be enjoyed on the rocks, on its own or in a mixed drink.
