Tequila is the traditional mezcal liquor produced in the Jalisco region of México using blue agave plants that are roasted. The roasted agave is later made into agave syrup and fermented to be distilled once or twice (depending on the brand). Tequila comes in two categories: pure agave tequila or simple tequila; the latter contains 50% agave and the rest is fermented sugars. Tequila is later on classified in white, silver, gold, rested and vintage varieties.
