La Alteña’s own estate-grown agave plants are still cooked the old-fashioned way, in large brick and stone ovens called hornos. The hearts of the agave, pi±as, are still crushed using a heavy stone wheel called a tahona. Today a tractor pulls the wheel, instead of a mule. El Tesoro is still double-distilled to 80 Proof, without any additional water or sugar for a truly authentic Tequila flavour. Many of the employees at La Alteña’s are third and fourth generation relatives of the people who helped Don Felipe create El Tesoro more than 65 Years ago. El Tesoro is still made with 100% Agave.
