Siete Leguas is distilled at two different distilleries: Fábricas El Centenario and La Vencedora. The former employs more traditional methods including the use a mule-drawn tahona and wild yeast fermentation while the latter uses a molina (a modern mill) to crush the agaves and their own cultivated yeast strain. Both are distilled in copper pot stills and the two tequilas are blended together to create the final product.
