Within these fields are the towns of Tequila, Arenal, Amatitan and Teuchitlán with large tequila production facilities. This site contains an inventory
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.
