Tequila is a distilled beverage made primarily from the blue agave plant, which is native to Mexico. It can only be called tequila if it is produced from blue agave plants grown in specific regions of Mexico and follows traditional production methods. The blue agave plants take 8-12 years to mature, after which the core pineapple-like pina is harvested and cooked to extract its fermentable sugars. The extracted agave juice is then fermented and distilled twice before aging in oak barrels, resulting in tequila varieties that differ based on aging time. Tequila production and labeling is regulated by Mexican laws to ensure quality and authenticity.
