Beam Suntory is celebrating the 80th anniversary of La Alteña distillery in Jalisco with the launch of a limited-edition Tequila under its El Tesoro brand.The El Tesoro 80th Anniversary Limited Edition is the distillery’s most aged Tequilas to date. Aged eight years in American oak ex-Bourbon barrels and with only eight casks of in existence, the expression will only be available in the US. Since the founding of El Tesoro tequila in 1937 by tequilero Don Felipe Camarena, the new expression is a celebration of the distillery’s 100% estate-grown agave. “In truth, my grandfather created a very inefficient process for making tequila,” said Carlos Camarena, Don Felipe’s grandson and master distiller for El Tesoro. “Yet it is these unique and stubborn production methods that make our tequila so special, and perhaps the most authentic. Eighty years later, we don’t care that there are faster ways to make tequila now. We care about the flavour, and the fact of the matter is that our method tastes better and is the best way to honour the agave.” The process begins with the 100% estate-grown blue agave which grows for up to eight years in La Alteña’s mineral-rich soils and highlands climate, giving them a spiciness that is not often found in Jalisco. Once the agave reaches peak maturity, it is harvested by hand, removing the waxy stem to give it for a smoother flavour.. After harvest, the hearts of the blue agave – called the piñas – are cooked in an old-fashioned hornos oven for three straight days. The cooked pinas are then slowly crushed to release all their juice under a massive, two-ton volcanic tahona wheel. For this 80th Anniversary Edition, the liquid extracted is then distilled to 85 proof at a low temperature in copper stills, that were made to Don Felipe’s specifications. El Tesoro is believed to be the only tequila to distill to proof, with no sugar or water added. El Tesoro 80th Anniversary Edition will be available with a suggested retail price of US$199.99 for 750ml. For a limited time only, it will join El Tesoro’s portfolio including: Blanco, Reposado, Añejo, and Paradiso Extra Añejo.
