Like tequila, the best mezcals say “100 percent agave.”

Several species of agave are used when making mezcal, most derived from the Agave angustifolia. Laws regarding process and classification of mezcals are not as defined as they are with tequila.

To soften the aroma, modern mezcal distilleries filter mezcal through charcoal, cellulose, or through sand to refine the texture and clarity.

Mezcals, on average, are not aged. However, some premium brands give their mezcals time in a barrel, infusing the liquor’s defining smoky flavor with oak properties.
