1942. In 1942, Don Julio Gonzales began perfecting the art of tequila making. From the cultivation of the agave to the final product, he refined an intricate process that produces one of Mexico's most exquisite tequilas. The process begins by hand selecting the finest agave plants at the peak of their maturity. The agave is then slowly cooked for an average of 72 hours cycles in traditional masonry ovens and double distilled. This exceptional tequila is crafted from the finest agave and aged until it reaches extraordinary levels of flavor and characters. Don Julio 1942 tequila coats the palate with agave and vanilla flavor, sun-ripened tropical fruits and spiced undertones to create a wonderfully unique tequila experience. www.diageo.com.
