DeLéon 51 is inspiring a cult following among spirits lovers, and at 102 proof, it’s the only Tequila in the world that’s cask-strength (51% abv). Classified as extra añejo, a designation for Tequilas aged a minimum of three years in oak barrels, DeLéon 51 is unique in that it spends 51 months in Haute Futaie French oak from famed cooper Seguin Moreau. Unlike other Tequila producers who use authorized additives like oak extract, caramel and sucrose, this expression focuses on purity, with its subtle notes of grass, pepper and citrus. Located in the town of Purísima del Rincon (which translates as “the purest of the corner”), Brent Hocking, founder and CEO of DeLéon, says the distillery sources its water from an “unprecedented three spring wells that register the purest water in the entire country of Mexico.” Packaging reflects the brand’s exclusive aesthetic: A rich leather box opens to reveal a sleek glass bottle with an ornate gold and copper closure created by Malibu-based jeweler Bill Wall, whose designs have been worn by Hollywood stars like Jay-Z and Nicollette Sheridan. Available to consumers in 11 states, the bottling fetches $250 per 750 ml.
