100% de Agave

What is 100% de Agave? 100% de Agave is a legally regulated label designation on tequila certifying that every fermentable sugar in the bottle comes exclusively from Blue Weber Agave (Agave tequilana cv. Weber Azul), with no added cane sugar, corn syrup or other sweeteners. The wording distinguishes pure agave tequila from mixto, which may be only 51% agave-derived with up to 49% of its sugars sourced elsewhere. The designation is governed by Mexico's NOM-006-SCFI-2012 standard and certified by the Consejo Regulador del Tequila (CRT). Phrases like "made with blue agave" do not qualify — only the explicit "100% agave" wording (or equivalents such as "100% Blue Agave" or "100% Puro de Agave") carries the certification.

Production and Origin

Authentic tequila comes from a single cultivar, Agave tequilana Weber blue variety, scientifically described by Weber in 1902. The plant is cultivated within five authorized Mexican states: Jalisco in its entirety, plus designated municipalities of Guanajuato, Michoacán, Nayarit and Tamaulipas. Blue agave grows slowly, with piñas (the harvested hearts) reaching maturity at roughly 7 to 14 years and typically weighing between 40 and 90 kilograms.

Every certified tequila — whether 100% agave or mixto — must be bottled at 35 to 55% ABV and undergo a minimum of two distillations. A crucial distinction at the bottling stage: 100% agave tequila must be bottled within Mexico, while mixto may legally be exported in bulk and bottled abroad. Each certified bottle also carries a NOM number identifying the distillery of origin, the CRT seal, and the Hecho en México marking.

Categories and What to Look For

The 100% agave designation applies across all aging categories defined by the standard. Blanco (also called Plata) is unaged or rested less than two months and, in the silver class, is prohibited from carrying additives — making it the purest expression of the agave itself. Joven or Oro is typically a blended or colored style, Reposado rests between two and twelve months in wood, Añejo matures from one to three years, and Extra Añejo spends three years or more in barrel.

When shopping, the exact wording on the label matters. A bottle that does not explicitly state 100% agave is mixto by default, even if the front label mentions blue agave prominently. The CRT requires the precise phrasing to certify purity, so reading the small print — alongside the NOM number and CRT seal — is the most reliable way to confirm what is in the glass.
