 Oaxaca has 570 of the 625 mezcal production facilities in Mexico, but some in-demand mezcals come from Guerrero, as well.In Tamaulipas, 11 municipalities have received authorization to produce authentic mezcal with the hopes of competing for a piece of both the Mexican national and international markets.The agave used here is "agave Americano, agave verde" or "maguey de la Sierra", which are native to the state.
