Tonic Water. The London Essence Company Original Indian Tonic is beautifully versatile, with a refreshing citrus forward profile. The addition of our distilled juniper essence delivers a gently bitter finish and is suitable for those who are seeking a more approachable tonic water. Juniper berries are steeped prior to distillation to create our unique essence, and are combined with a variety of citrus notes, including aromatic calamansi, for an almost tropical edge. This unique blend results in our most versatile tonic, aided by a delicate level of sweetness, to allow the notes of your spirit to shine through. The London Essence Company Original Indian Tonic is an exemplary choice for pairing with premium gin or try with a dark rum.
