Tequila Herradura 150 Aniversario Limited Production One Time Offering. In honor of our 150th Anniversary, we proudly present Tequila Herradura Aniversario - a 100 month aged Extra Aejo. Made from time honored traditional methods, we aged the finest Blue Weber Agave for 100 months in American White Oak barrels creating the ultimate Extra Anejo expression representing 150 years of tequila making excellence. *NOTICE: Our 150th Anniversary tequila has been aged for 100 months in American White Oak barrels, however the barreling date on the packaging, 11/12/12, has been printed incorrectly. The correct barreling date is, 2/12/11, reflecting 100 months of aging.
