This gin-based aperitif is officially classified as fruit cup—a beverage that is meant to be mixed into a long drink. It was invented in 1840 by a London oyster bar owner James Pimm who first offered it to his guests as a health tonic.
Although the recipe is not known, the original Pimm’s No. 1 is based on gin while its characteristic flavor comes from an infusion of a secret combination of herbs and spices. Through history, other spirit bases were used, but could never catch up with the popularity of the original No 1.
