Tequila, Jalisco products distilled from agave grown in certain regions of Mexico. These regions are Tequila and surrounding municipalities as well as parts of the State of Tamaulipas. The lands in Tamaulipas were added later as the need to cultivate blue agave grew, and these lands and the agave grown on them were certified by the Mexican government for quality. The term is also limited to fifteen production facilities such as Tequila Sauza, Tequila Orendaín, and Jorge Salles Cuervo. Long-established distilleries here produce between 500 and 1000 liters a day but this is not enough to meet the international demand for the
Tequila, Jalisco produced here. Other attractions on the route include archeological sites, old mansions and opal and obsidian mines. The archeological sites primarily belong to a culture known as the Guachimontones located in the municipalities of Teuchitlan and Magdalena. In a number of the old hacienda/distilleries, visitors are invited to try their hand at some of the aspects of tequila making, such as cutting the spines off the agave plant. Most of these haciendas also have tasting rooms and restaurants. Along the route is the Tequila Volcano. The Tequila Express is a train for tourists which has been in operation since 1997.
