Tequila

Law, Production & Sensory Analysis.

10 chapters · about 25 min · built for practical bar knowledge

Tequila is a protected Mexican spirit defined by origin, Agave tequilana Weber variedad azul, two legal categories and five classes. Start with the law, then follow agave → sugar → fermentation → distillation → maturation → label → glass.

Scope Start with protected origin and category rules, then follow the production decisions that shape the label and the glass.

Guide contents

Ten short chapters. Start with the DOT, then follow agave → fermentable sugar → fermentation → distillation → class → maturation → label → glass. Sources and further reading sit together at the end.

01

The DOT defines Tequila

Origin, one agave variety and NOM-006 establish the protected category before producer choices begin.

Tequila is protected by the Denominación de Origen Tequila and governed by NOM-006-SCFI-2012. Qualifying production takes place inside the protected territory and uses Agave tequilana Weber variedad azul as the agave source.

The DOT covers 181 municipalities across Jalisco, Michoacán, Tamaulipas, Nayarit and Guanajuato. Origin is part of Tequila’s legal identity.

CRT · CONSEJO REGULADOR DEL TEQUILA Conformity assessment and certification

The CRT is an accredited and approved conformity-assessment organisation for the Agave-Tequila chain. It works as an inspection unit, testing laboratory and certification body, verifying compliance with NOM-006 across production, labelling and commercialization while helping safeguard Tequila authenticity and the Denominación de Origen.

IMPI · DENOMINATION AUTHORITY Authorization to use the DOT

IMPI is the Mexican authority that authorizes use of the Denominación de Origen. A Tequila producer therefore needs the relevant DOT authorization and conformity certification within the regulated system.

Category tells you the sugar source

The two legal categories answer one practical question: where did the fermentable sugars come from?

NOM-006 recognises two Tequila categories. Category describes the source of fermentable sugars; quality and style require separate assessment.

01

Tequila 100% de agave

All fermentable sugars come from Blue Weber agave grown within the protected territory. The product is bottled at origin under the authorised producer’s control.

02

Tequila

At least 51% of the reducing sugars come from Blue Weber agave. Up to 49% may come from other permitted reducing sugars during formulation.

Label language: “Mixto” is common industry shorthand. The legal category name is Tequila.

Blue Weber agave sets the starting point

The legal variety is fixed. Agriculture, maturity, harvest and handling create variation before the distillery begins.

Agave tequilana Weber variedad azul, commonly called Blue Weber agave, is the permitted agave variety for Tequila. The plant develops over several years and is harvested when it has reached suitable development for production.

The piña contains the carbohydrates used in production, principally stored as fructans. Growing site, maturity, harvest timing, trimming and handling all influence the raw material that reaches the distillery.

Learning point: origin and agriculture set the starting material; processing determines how that material is transformed.

04

Hydrolysis unlocks fermentable sugar

The piña stores carbohydrates. Production must make those carbohydrates available to yeast.

What is hydrolysis?

Hydrolysis is a reaction in which water breaks larger molecules into smaller ones. In Tequila production, it makes the agave’s fructans available as fermentable sugars.

After jima, hydrolysis is followed by extraction, recovering the sugar-rich liquid that will be prepared for fermentation.

Producer choice

Stone ovens, masonry ovens and autoclaves are established cooked-agave routes. Diffuser systems can change the order by extracting carbohydrates before hydrolysis. Tahona and roller-mill systems are common extraction approaches for cooked agave.

05

Fermentation and distillation build the spirit

Yeast creates alcohol and aroma precursors; distillation then selects and concentrates volatile material.

Fermentation

Yeast converts fermentable sugars into alcohol and carbon dioxide while creating compounds that contribute to Tequila’s final sensory character. Yeast strain, temperature, time, vessel and the presence or absence of agave fibre can all influence style.

Distillation

Distillation concentrates alcohol and redistributes volatile compounds. Still design, number of passes, heating rate, reflux and run selection are producer choices within the standard.

Tequila may be distilled in pot-style alambiques or column stills, both of which are recognised within CRT inspection requirements.

Class tells you what happened after distillation

Category explains sugar source. Class explains post-distillation treatment and maturation framework.

Blanco / Plata

Less than 2 months in wood

Transparent; commercial strength is adjusted with dilution water. It may spend less than two months in oak or encino.

Joven / Oro

Blend / abocamiento

May combine Blanco with Reposado, Añejo or Extra Añejo, or result from abocamiento of Blanco.

Reposado

Minimum 2 months

Matured in direct contact with oak or encino. The 600 L vessel maximum applies to Añejo and Extra Añejo; Reposado is defined by direct wood contact and its minimum time requirement.

Añejo

Minimum 1 year · ≤600 L

Matured in direct contact with oak or encino vessels with a maximum capacity of 600 litres.

Extra Añejo

Minimum 3 years · ≤600 L

Matured in direct contact with oak or encino vessels with a maximum capacity of 600 litres.

Cristalino: a commercial style commonly applied to filtered aged Tequila. The legal class list remains Blanco, Joven, Reposado, Añejo and Extra Añejo.

Vessel and time shape maturation

Reposado, Añejo and Extra Añejo share wood contact, but their legal time and vessel rules differ.

PIPÓN

A large wooden vessel especially relevant to Reposado. Capacities can be far greater than a conventional barrel.

LEGAL DISTINCTION

Reposado requires at least two months in direct wood contact. Añejo and Extra Añejo add minimum time plus a 600 L maximum vessel size.

Maturation. Previous fill, heat treatment, vessel size and time can all change the way the spirit develops in wood.

A larger vessel generally gives less wood surface area per litre than a small barrel, so extraction and wood influence tend to develop differently.

A Tequila can spend more than one year in a large pipón and remain Reposado because Añejo also requires maturation in vessels no larger than 600 litres.

NOM-006 uses the legal terms roble o encino. This guide keeps that wording without forcing a species translation.

Why can a Tequila mature for more than one year and still be Reposado?

08

Abocamiento is a separate production choice

The sugar-source category and post-distillation treatment answer different questions.

NOM-006 defines abocado as the procedure used to soften or modify Tequila through specified ingredients. An abocante is an ingredient used for that purpose; abocamiento is carrying out the procedure.

Taste from evidence

Describe what is in the glass first. Use verified production information to explain plausible causes.

Structured tasting helps separate observation from assumption. Record appearance, aroma, palate and finish, then interpret the style using the production information that is actually available.

Five-question tasting tool

1. Appearance

Observe: colour, depth and clarity. Use colour as appearance evidence. Age and quality require separate evidence.

2. Aroma

Look for: cooked agave, grassy / herbaceous notes, citrus, pear, stone fruit, banana, pineapple, floral tones, black or white pepper, vanilla, coconut, caramel, toast and oak spice where present.

3. Palate

Assess: flavour intensity, agave character, fruit, floral notes, pepper, spice, texture, oak influence and integration. Note how alcohol and flavour intensity work together.

4. Finish

Follow: length and development. What remains: agave, pepper, tropical fruit, herbs, oak, vanilla or drying tannin?

5. Interpretation

Describe the style: fresh and agave-led, fruity and floral, grassy / herbaceous, peppery, earthy / savoury, rich and textural, oak-led or balanced between agave and maturation.

When tasting professionally, what comes first: observation or production explanation?

The takeaway

Read the law.
Then read the glass.

Origin defines the category. Category gives the sugar source. Class gives the post-distillation framework. The NOM registration identifies the authorised producer. Tasting tells you what the spirit actually shows.
