What is tequila? Well, it is a distilled alcoholic beverage made from the blue agave plant, primarily in the area surrounding the city of Tequila, 65 km (40 miles) northwest of Guadalajara, and in the highlands (Los Altos) of the western Mexican state of Jalisco. Tequila is most often made at a 38% alcohol content (76 US proof) but can be produced between 35-55% ABV.
The first distillation of what we now know as tequila took place in 1530, just 30 years after the Spanish conquest of Mexico. It was created by a man named Martin de la Cruz, who was inspired by a similar drink being made in Spain. Tequila quickly became popular throughout Mexico, and by the early 1800s, it was being exported to other countries.
Tequila is made from the agave plant, which is native to Mexico. There are more than 200 varieties of agave, but only one, the blue agave, is used to make tequila. The blue agave plant takes anywhere from six to twelve years to mature and can grow up to 2.5 meters (8 feet) tall. Once the plants are mature, they are harvested and the piñas (the hearts of the plants) are extracted.
The piñas are then chopped into small pieces and placed in large ovens where they are slow roasted for several hours. This process breaks down the complex carbohydrates in the piñas into simple sugars, which are then used to produce tequila.
After the piñas have been cooked, they are mashed and placed in large fermentation tanks where yeast is added. The yeast causes the sugars in the mash to ferment and produces alcohol. The fermented mash is then distilled to create the great tequila!
The agave plant had been used in the preparation of alcoholic drinks for centuries; in fact the Aztecs had made a fermented drink from it called octli. In around 1600, the Marquis of Altamira, Don Pedro Sánchez de Tagle, first mass-produced tequilas in a factory he founded in Jalisco.
The agave plant is still harvested by hand, by workers called "jimadores" They work carefully to harvest the small Agave offspring without damaging the parent plant. The exact time of the harvest is very important, because if the agave plants are gathered too early in the season, the natural sugars will have yet to develop, and if it is gathered too late, the natural sugars will have already been used up by the plant.
More traditional companies still crush the plants with an old-fashioned stone wheel. The fermented juices are distilled, usually twice, though sometimes three times.
Tequila can be either blanco (white), which is also called plata (silver) or joven (young), or it can be aged in oak barrels, which gives it a golden or amber colour. Tequila that has been aged for more than two years is called añejo (aged). Tequila that has been aged for more than three years is called extra añejo (extra aged).
Tequila can be enjoyed neat or in cocktails such as the Margarita, Paloma, and Tequila Sunrise. Tequila is also used in cooking, for example in the popular Mexican dish Cochinita pibil.
