Cava de Oro Tequila Extra Añejo Cristalino is available only in Mexico and not exported to the US or Canada. Like all the tequilas from Cava de Oro, it is distilled from 100% blue weber agave harvested from both regions in Jalisco ---Los Altos and Tequila Valley. It spends 5 years aging in French white oak barrels before it is filtered clear and bottled at 38% ABV.
