Tradicional Aejo is 100% blue agave tequila aged in charred American oak, then finished in Irish single malt whiskey barrels. It is the pinnacle of the Jose Cuervo Tradicional line, which has been masterfully honed over 200 years. Carried out completely in the artisanal tradition developed by Jose Antonio de Cuervo: cooking the agave in clay ovens and distilling the tequila in copper stills. (40% ABV-80 proof) Founded in 1795, the Cuervo distillery, La Rojea, in Jalisco, Mexico, is the oldest active spirits distillery in Latin America. Jose Cuervo was the first commercial producer of tequila in the world.
