Mezcal (traditionally spelled mescal) is a Mexican distilled spirit that is made from the agave plant. Tequila is technically a mezcal, however, there are differences in production technique and in the types of agave used. Tequila is made from a single type of agave plant – the agave tequilana (blue agave) – and can only be produced in the state of Jalisco and in small parts of four other states.
Mezcal can be produced from up to 28 varieties of agave (including blue agave) and is made around the city of Oaxaca and, according to official government regulations (NOM -070-SCFI-1994), can also officially be produced in some areas of the states of Guerrero, Durango, San Luis Potosi and Zacatecas. Most mezcals are made from the Espadin agave, although some mezcal producers blend agave varieties to create a distinct flavor.
Mezcal traditionally has a very unique, smoky flavor that makes it fairly easy to distinguish from tequila. It also tends to taste sweeter, or richer, than tequila. Some mezcal producers have adopted production processes similar to tequila, and the resulting mezcal has flavor profile similar to tequila.
