Lepanto is the luxury offshoot of González-Byass which has the distinction of being the only Brandy de Jerez which is produced entirely from start to finish in Jerez. Lepanto PX Gran Reserva is produced from Palomino grapes grown in the region, which undergo a double-distillation process in the Los Arcos cellar between two Charentais pot stills from Cognac that date back to the 1960s. The distillate, or 'horanda', is aged for a minimum of 15 years in a solera system in sherry barrels once used for bourbon. They spend 12 years in barrels that had been used for Tio Pepe sherry and 3 years in barrels that had aged Noe, a Pedro Ximénez sherry that ages for 30 years.
