A bright, bitter, and citrus-forward tonic water made from whole ingredients including fresh lemongrass, cinchona bark, and allspice berries. This recipe has its roots in the long history of cinchona bark, the source of quinine, a powerful alkaloid long used to support the body during fever and infection, particularly malaria. Traditionally prepared as a decoction (strong herbal tea), its intensely bitter constituents were valued for their ability to reduce fever and interrupt cycles of illness.
In the 18th and 19th centuries, British officers stationed in tropical regions were given quinine regularly and began mixing it with sugar, citrus, and water to make it more palatable, eventually adding gin and shaping what we now know as the classic gin and tonic. The flavor of this homemade tonic water is thirst-quenching and citrus-forward, with fresh lemongrass bringing a bright, refreshing quality and allspice berries lending a warm, aromatic note. The bitterness is not just for flavor, but reflects the traditional role of bitter plants in supporting digestion, making this a refreshing herbal drink to enjoy on a hot summer day and a small way to connect with the long history of this remarkable plant.
