From Producer‚Äôs Website: This is the 100% weber blue agave base from which all of our flavor offerings are crafted. Harvested by the same families who have supplied our partner distillery, el viejito, for the last 70 years, the agave is hand cut (axed, actually) into quarters and skillfully loaded into brick ovens. Never compromising quality for so-called "efficiency", modern autoclaves are never used for production. Every batch is cooked in traditional brick ovens which allows for the best interpretation of the coveted agave spirit. This is the beautiful foundation of tradition that Libre is privileged to stand on to bring about our non-traditional expressions, respectfully.
