The blue agave plant has spiked leaves and a round, fleshy core (the piña). The leaves are chopped off and the core is cooked and crushed to create juice, which is fermented and distilled to make tequila. The resulting unaged, clear tequila is then diluted with water to bring the alcohol content down to around 40%. Pure tequila is distilled 100% from the sap of the blue agave plant, while mixto tequilas only need to
Tequila fruitier-tasting tequila, while lowland agaves give the tequila an earthier flavor. Unlike other tequila production steps, fermentation is one of the few steps out of the control of human beings. Fermentation is the conversion of sugars and carbohydrates to alcohol through yeast in anerobic conditions, meaning that oxygen is not present during the process. Fermentation is also carried out in a non-aseptic environment which increases the bacterial activity of tequila. The participation of microorganisms from the environment (yeasts and bacteria) makes fermentation a spontaneous process which gives rise to many byproducts that contribute to the flavor and aroma of tequila.
