Tequila Express Tequila Express The Tequila Express (or Tequila Train) is a Mexican regional train service that operates from Guadalajara, Jalisco, to the Tequila Herradura distillery at the San José del Refugio Hacienda in the municipality of Amatitán, Jalisco. Amatitán is approximately northwest of Guadalajara and southeast of the town of Tequila, Jalisco.

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.
