The service began operating in 1997, concurrent with the elimination of general passenger rail service by
Tequila fructose. Through the fermentation process, many factors influence the higher alcohol content of tequila, which are molecules such as isobutyl alcohol and isoamyl alcohol, and ethanol. These parameters include the type of yeast strain, the age of the agave plant itself, temperature, and the carbon/nitrogen ratio. However, the type of yeast strain used and the carbon/nitrogen factors have the biggest influence on the production of higher alcohols, this is not surprisingly as higher alcohol and ethanol production is an intrinsic property of the metabolism of each strain. The type of yeast most commonly found in tequila is "Saccharomyces cerevisiae", which
