Tequila Production Process

Tequila production is tightly regulated by NOM-006-SCFI-2012, the Mexican standard administered by the Consejo Regulador del Tequila (CRT). Every bottle must trace back to a registered distillery (identified by its NOM number) and follow strict production rules within designated regions.

Harvesting (Jima): Skilled workers called jimadores harvest mature blue agave plants (typically 7-10 years old) by hand, removing the leaves with a specialized tool called a coa to expose the piña (the heart of the plant, weighing 40-90 kg). Timing is critical—premature harvest yields less sugar, while overripe agave can develop undesirable flavors.

Cooking: Piñas are cooked to convert complex inulin carbohydrates into fermentable sugars. Traditional methods use stone or brick hornos (ovens) for 24-48 hours, producing richer, earthier flavors. Modern distilleries often employ stainless steel autoclaves (pressure cookers) that complete the process in 8-12 hours, yielding cleaner, lighter profiles. Some producers use diffusers, which extract sugars without cooking, though this method is controversial among purists.

Milling: Cooked agave is shredded to extract sweet juice (aguamiel). Traditional tahona wheels (large volcanic stone wheels) crush the fibers gently, while modern roller mills and shredders are faster and more efficient.

Fermentation: The aguamiel ferments in wooden vats or stainless steel tanks for 3-5 days (sometimes longer). Distilleries use proprietary yeast strains—some wild, some cultivated. By law, 100% agave tequila must ferment only agave sugars, while mixto (minimum 51% agave) may include cane sugar or other sugars.

Distillation: Tequila must be distilled at least twice in pot stills (alembiques) or column stills. The first distillation produces ordinario (around 20-25% ABV), the second yields tequila at 55-75% ABV. Copper stills remove sulfur compounds and add complexity; stainless steel preserves agave character.

Aging and Bottling: Blanco is bottled immediately or rested up to 60 days. Reposado, añejo, and extra añejo age in oak barrels per CRT regulations. Water is added to reach bottling strength (35-55% ABV, typically 38-40%).
