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. The train service is so named because it features tequila tastings and transports its passengers through blue agave fields to the distillery in Amatitán and towards (but not into) the town of Tequila. The service began operating in 1997, concurrent with the elimination of general passenger rail service by
Tequila produced during the thermal degradation of sugar. The most prominent furanic compounds include 2-furaldehyde and 5-methylfuraldehyde, which can contribute to the smoky flavor of tequila. Guaiacol also seems to contribute to Tequila's smoky flavor. Beta-demascenone contributes to the woody, floral taste of tequila. Volatile compounds that contribute to the overall taste and aroma of tequila can be quantitatively assessed and evaluated by gas chromatography. Discrimination tests such as duo-trio and triangle tests are also used to evaluate the quality of the tequila. If silver or white tequila is the desired final product, distillation is the final process it undergoes. Rested
