Tequila Patron Anejo. Patron Anejo is a distinctive blend of uniquely aged tequilas, all passed through small white oak barrels for at least 12 months. Similar to the distillation of wines, each vintage "pinas" by Patron Anejo, is fermented to produce a smooth and characteristically delicious tequila. Consumers who already enjoy aged spirits and seek a rich experience would trade every aged drink in the class with Patron Anejo.
