Thomas Henry Elderflower Tonic is created out of the true harmony between flowery elderflower and a gentle bitterness from the quinine. The elegance of the elderflower adds a whole new dimension to the sensory world of tonic. In the tradition of mixologists who like to give classic drinks a “twist”, we have reinterpreted the tonic water: through the taste of elderflower, which for centuries has been known for its healing power and floral taste.
