Their story began with John Sober when he inherited a small distillery atop Mount Gilboa in the parish of Saint Lucia in Barbados. He hired a fourth-generation Barbadian, Sir John Gay Alleyne to usher in a new era for the distillery. Success comes and the family decides to associate their name with the distillery. The water used comes from an artesian well from 1703. Two types of fermentation are used: closed fermentation for distillation in a column based on endemic yeasts and initial fermentation in the open air for distillation in a still where the breeze transports native yeasts. The sugar cane is sourced locally and picked by hand. Mount Gay has been legally established since 1703, making it the oldest continuously operating rum distillery in the world.
