Patrn Extra Aejo 10 Aos is the oldest tequila made at the Hacienda Patrn distillery in Jalisco, Mexico. The finest 100% Weber Blue Agave is harvested, baked, distilled and then aged for an impressive 10 years in American oak barrels and hybrid American/French Limousin oak barrels. It is presented in a hand-blown glass replica of the very first Patrn bottle.
