Tequila with salt and lime across the rest of the world. The red volcanic soil in the region around the city of Tequila is particularly well suited to the growing of the blue agave, and more than 300 million of the plants are harvested there each year. Agave grows differently depending on the region. Blue agaves grown in the highlands Los Altos region are larger in size and sweeter in aroma and taste. Agaves harvested in the lowlands, on the other hand, have a more herbaceous fragrance and flavor. Mexican laws state that tequila can only be produced in the state
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.
