Right after the agave juice (wort) has stopped fermenting, it is piped into stills, where it undergoes a first distillation whose products are carefully separated into 3 parts called heads, heart and tails. Then the heart part undergoes a second distillation in copper stills and the resulting liquor is again separated into heads, heart and tails. Only the heart produced by the second distillation is used to make Tequila Herencia Mexicana.
