What Is Authentic Mezcal?
Certification for mezcal is still being defined and less restricted than tequila, but production is somewhat regulated by the Mexican government.
Both tequila and mezcal have been listed with DO or AO status (denomination of origin or Appellation of Origin), like Champagne and Prosciutto, plus Geographical Indication (GI). This means that the territory influences the product.
Mezcal can only be made in specific regions in certain Mexico states: Oaxaca, Durango, Guanajuato, Guerrero, San Luis Potosi, Sinaloa, Tamaulipas, Zacatecas, Michoacan, and Puebla.
Together, they form the world’s largest denomination of origin, above scotch whisky and tequila. Outside of these regions, bottles must be labelled as ‘distilled agave’ or destilado de agave.
In Mexico, mezcal is regulated under Norma Oficial Mexicana (NOM), by the industry body COMERCAM (Consejo Mexicano Regulador de la Calidad del Mezcal, or Mexican Regulatory Council for Mezcal Quality).
By law, mezcal must have a minimum of 80% agave sugar, while the rest can be made up with other sugars. But similar to tequila, the best mezcal is made with 100% agave.
