Aromatic Gin & Tonic is a Gin & Tonic with a tonic with an exceptionally spicy character with a hint of citrus. Fever-Tree Aromatic has been made exclusively with natural ingredients such as Jamaican pepper, vanilla from Madagascar, bitter orange from Tanzania, high-quality quinine from Congo, green ginger, and Angostura bark from South America. The bark is the reason for the subtle pink color of tonic water.
