El Tesoro Tequila Extra Añejo 85th Anniversary Limited Edition is an ultra-premium tequila crafted in honor of a remarkable milestone—the 85th anniversary of the La Alteña Distillery, where time-honored traditions have been meticulously upheld since 1937. El Tesoro treasures its most precious asset, the blue Weber agave, and this limited release pays homage to their commitment to producing agave-forward tequila of the highest quality. Master Distiller Carlos Camarena, known for his dedication to the craft, collaborated with Jim Beam Master Distillers Booker and Fred Noe, who share a passion for traditional spirit-making methods. This extraordinary tequila was aged in oak barrels previously used for Booker's 30th Anniversary Bourbon, enriching it with the beloved vanilla flavor cherished by Fred Noe. Each barrel was patiently safeguarded for a minimum of 36 months until reaching its peak of maturity.
