Valley (Los Valles) vs. Highlands (Los Altos): What’s the difference?
Tequila acquires much of its character from the terroir (soil). Dark red soil rich in iron content is the predominant terroir in the highlands region.
Agave grown in the Highlands tend to be larger due to cooler average temperatures from the higher altitude and is generally considered to contain a higher level of sweetness, while agave plants from the Valley’s rich volcanic soil tend to have earthier qualities. It’s important to note that blind taste tests have shown these differences are subtle at best.
