The main difference between Highland and Lowland tequila lies in the region where they are produced within the Mexican state of Jalisco. Tequila from the Highlands (Los Altos) is produced in the higher altitudes of Jalisco, where the climate is cooler and the soil has a higher mineral content. Conversely, Lowland tequila (Tequila Valley) is produced in the lower altitudes, where the climate is warmer and the soil has a lower mineral content.
Due to the climatic and soil differences, Highland tequila tends to have a sweeter, fruitier taste with floral and herbal notes. Lowland tequila, on the other hand, is characterized by more earthy and vegetal notes with a stronger, spicier flavor.
Another important factor in the taste of tequila is the type of agave used. Highland tequila typically uses agaves with a higher sugar content, while Lowland tequila uses agaves with a lower sugar content. This can contribute to the differences in the flavors and aroma of both tequilas.
Overall, the difference between Highland and Lowland tequila is quite significant, which contributes to their unique taste profile. While both regions produce excellent tequilas, the terroir influences their characteristics, and as a result, preference for one region over the other tends to be a matter of personal taste.
