Chipotle Mexican Grill, Inc. announced that it is adding premium Patrón margaritas to the menu in its U.S. restaurants. The new margarita is hand-made for each customer using Patrón Silver tequila, triple sec, a blend of fresh lime and lemon juices, and organic agave nectar. The Patrón margarita will be available in about 900 Chipotle restaurants beginning April 29, 2013. Served on the rocks with a wedge of lime, the premium Patrón margarita is a simple recipe using only a few ingredients, and will be offered to customers alongside another margarita option made with Sauza tequila. The Sauza margarita will be available as a house option at a lower price, but will be made using the same recipe as the Patrón version.
