Mexico's Agave Rescuers plan to use Tequila, which was completely exclusive and the first. In April 2013, Issaquah, Washington- Federico Ramos, co-owner of the Agave restaurant, led a team to the Casa Herradura, in the heart of Tequila Heartland, Mexico, to get just one barrel of tequila. Tequila is produced exclusively from the Azul Agave plant. It grows in one of the five Mexican states, so its market value and demand are much higher. The agave plant is cut, pruned, pressed, and distilled to create the final tequila.
