The differentiation lies primarily in aging. One type, often clear, is bottled soon after distillation, showcasing the pure flavors of the agave. The other, typically amber-hued, undergoes aging in oak barrels, imparting notes of vanilla, caramel, and spice. For example, a blanco expression highlights the agave’s inherent characteristics, while a reposado or aejo develops complexity from the barrel’s influence.
Understanding this distinction is vital for appreciating the spectrum of flavors available. This knowledge allows consumers to select a spirit that aligns with their preferences, whether seeking the vibrant taste of unaged agave or the nuanced profile developed through maturation. Historically, aging techniques have evolved, influencing the character and perceived value of different expressions.
