Highland Tequila (also known as "Los Altos") is an extensive, high altitude region in Mexico, located in the eastern part of the state of Jalisco. The region is characterized by its higher elevations, ranging from 2000-2500 meters above sea level. Due to the milder climate and mineral soils, Los Altos is perfect for growing agave compared to the lower altitude areas.
Los Altos is known for producing premium tequila, which is often perceived as smoother, fruitier and slightly sweeter, in contrast to tequila from the lower elevation areas (Lowlands), which is often perceived as smokier and earthier. Tequila made in Los Altos often has flavors of citrus, vanilla and honey.
Some of the most well-known tequila brands made in Los Altos include Fortaleza, Casamigos, El Tesoro, and Don Julio. The agave plants in this area required a longer growing season and take longer to mature. The resulting tequila varieties are often of particularly high quality, which justifies the higher prices. Many tequila connoisseurs appreciate the high-quality tequilas from Los Altos for their rich flavor and pleasant texture.
