Gran Centenario® Cristalino starts out as a blend of our finest reserves of Añejo and Extra Añejo tequilas, twice distilled in copper pot stills, and aged in new American oak. Once married, the tequila is finished in Calvados casks for extraordinary character. It then undergoes a proprietary process that culminates in a meticulous filtration through Mexican silver. The result is an exceptionally balanced tequila of flawless clarity and smoothness.
