Using the name of ‘Tequila’ for agave spirits is regulated, and can only be used for blue agave spirits produced in specific places in Mexico: the state of Jalisco, and parts of Guanajuato, Tamaulipas, Michoacán, and Nayarit. This leaves distillers outside of those regions, especially in the US, with the need to create alternative titles for their agave produced spirits.
