Tequila Glossary

Every tequila term that actually matters — agave to añejo, tahona to NOM — defined in plain English and pressure-tested against bottles we've tasted.

Tequila has a vocabulary problem: half the words on the bottle are marketing, and the ones that actually tell you something — NOM, additive-free, tahona, diffuser — are the ones nobody explains. This glossary fixes that. Every entry is a plain-English definition first; where it helps, we add how the term shows up in the glass, the rule behind it, and the myth it's usually wrapped in.

#

100% Agave

A tequila made entirely from Blue Weber agave sugars, with no other fermentable sugars added. The phrase must appear on the label; anything without it is a mixto.

Pro tip

If the front label doesn't say "100% agave," assume it's a mixto. This is the single most important thing to read on any tequila bottle.

Don't get fooled

“100% agave” still allows up to 1% undisclosed additives — so it guarantees the sugar source, not purity. It is a floor, not a gold star.

A

Additive-Free

Tequila made with no permitted additives — no sugar-based syrup, glycerin, oak extract, or caramel colouring. Its flavour comes only from agave, fermentation, distillation, and (for aged expressions) the barrel.

In the glass

It's the first thing we look for. In our tastings, verified additive-free bottles like Fortaleza and El Tesoro taste of real cooked agave — earthy, peppery, mineral — where additive-heavy tequilas read smooth-but-hollow, like agave-flavoured candy.

The rule

Tequila regulations (the NOM, enforced by the CRT) permit up to 1% additives without any label disclosure. “Additive-free” is a voluntary claim, best confirmed by independent testing such as Tequila Matchmaker's.

Don't get fooled

“Smooth” is not a sign of quality — it's often the additives talking. Sugar and glycerin exist precisely to soften and sweeten a spirit.

Agave (Blue Weber)

The succulent plant tequila is made from — specifically Agave tequilana 'Weber Azul'. It takes six to eight years to mature before harvest, and by law tequila can be made from no other agave variety.

Pro tip

Agave is not a cactus. It's closer to a lily, and its slow maturity is why great agave spirits cost what they do.

Alambique (Pot Still)

/ah-lam-BEE-keh/

A traditional copper or stainless pot still used for the batch distillation of tequila, almost always in two passes (ordinario, then the final spirit).

In the glass

Pot-distilled tequilas tend to keep more agave weight and texture than lighter column-distilled ones — part of why the traditional producers we rate highest lean on them.

Añejo

/ah-NYEH-hoh/

“Aged” tequila, matured 1 to 3 years in oak barrels no larger than 600 litres. Richer, smoother, and oakier than reposado, with caramel and vanilla layered over the agave.

In the glass

The best añejos never bury the agave under wood. El Tesoro Añejo is our benchmark — a year-plus in ex-bourbon oak, still unmistakably agave underneath.

The rule

The 1–3 year window is set by the CRT. Barrels must be oak and no larger than 600 litres.

Autoclave

A large stainless-steel pressure cooker used to cook agave quickly (hours instead of days). Efficient and common, but faster and hotter than a traditional brick oven.

Don't get fooled

Autoclaves aren't automatically “bad” — plenty of good tequila uses them — but the fastest, hottest cooking can strip nuance. Slow horno cooking is prized for a reason.

B

Blanco (Silver / Plata)

Unaged tequila, bottled straight after distillation (or rested under two months). The purest expression of the distillery's agave — nowhere for flaws to hide.

In the glass

Blanco is our favourite way to judge a distillery. With no oak to lean on, quality is naked: Fortaleza, Siete Leguas, and G4 all shine here.

Pro tip

Want to know if a brand can actually make tequila? Taste the blanco. Barrels can flatter mediocre spirit; blanco can't.

C

Column Still

A continuous still that produces a lighter, higher-proof, more neutral spirit than a pot still. Used by many larger tequila producers for efficiency and consistency.

Don't get fooled

Column distillation isn't a shortcut like a diffuser — it's a legitimate method — but pushed too far it thins out the agave character that makes tequila interesting.

Cooked Agave

The roasted agave heart after cooking, which converts its starches to fermentable sugars and develops the sweet, vegetal, caramelised flavour at the core of real tequila.

In the glass

“Cooked agave” is the note we chase in every tasting — that sweet-roasted, slightly earthy character. Its absence is often the first sign of a diffuser-made or additive-smoothed spirit.

Copita

/koh-PEE-tah/

The small, wide-mouthed tasting glass traditionally used for sipping tequila and mezcal neat — the agave equivalent of a whisky Glencairn.

Pro tip

Sip good tequila neat from a copita or a small tulip glass, at room temperature. Skip the shot, the lime, and the salt — those exist to mask cheap mixto.

Cristalino

/kris-tah-LEE-noh/

An aged tequila (usually añejo or extra añejo) filtered through activated charcoal to strip the colour back to clear, keeping some barrel flavour while looking like a blanco.

The rule

Cristalinos are frequently additive-forward; the sweet, soft profile many carry is a classic sign of permitted additives at work.

Don't get fooled

Cristalinos are a marketing category, not a quality one. Filtering removes character along with colour, and many are sweetened to compensate — you often pay añejo money for less.

CRT (Consejo Regulador del Tequila)

The Tequila Regulatory Council — the body that certifies and enforces the tequila standard, verifies agave content, and issues every producer's NOM number.

The rule

The CRT audits distilleries and inspects agave and production against the Norma Oficial Mexicana (NOM). Its oversight is what makes 'tequila' a protected, verifiable term.

D

Denominación de Origen (DO)

/deh-noh-mee-nah-see-OHN deh oh-REE-hen/

The legal designation of origin restricting tequila production to Jalisco and limited municipalities in four other Mexican states. Agave spirit made elsewhere legally cannot be called tequila.

Pro tip

This is why an 'agave spirit' from outside the zone isn't tequila — same plant, different (or no) rules. The DO is a guarantee of place.

Diffuser

An industrial machine that extracts agave sugars with high-pressure hot water and often acid or enzymes — sometimes from raw, uncooked agave — before any traditional cooking.

In the glass

Diffuser tequila often tastes thin and generically sweet, leaning on additives to fill the gap. It's the opposite of the tahona-made bottles we recommend.

Don't get fooled

The diffuser is the biggest quality shortcut in modern tequila. It maximises sugar yield and slashes cost, but strips the agave character that cooking and crushing develop. Many big brands rely on it and never say so.

E

Estate-Grown

Tequila made from agave the distillery grew itself, rather than buying from third-party farmers — giving control over ripeness, sourcing, and consistency.

In the glass

Estate control shows. Producers like El Tesoro and Fortaleza that grow and harvest their own agave tend to deliver the most consistent, expressive spirit year to year.

Extra Añejo

/EKS-trah ah-NYEH-hoh/

“Ultra-aged” tequila, matured more than 3 years in oak. The deepest and most whisky-like category, with dried fruit, chocolate, and spice over the agave.

In the glass

A great extra añejo rivals fine brandy. Tears of Llorona (five years, multi-cask) is a standout; Tapatio Excelencia proves you don't need celebrity money to drink one.

The rule

Requires more than 3 years in oak barrels no larger than 600 litres, certified by the CRT.

H

Highlands (Los Altos)

/lohs AHL-tohs/

The higher-altitude agave region east of Guadalajara, with iron-rich red clay soil. Highland agave tends to yield sweeter, fruitier, more floral tequila.

In the glass

You can taste the region. Highland bottles like El Tesoro read bright, citrusy, and floral, where Valley agave runs earthier and more mineral.

Horno (Brick Oven)

/OR-noh/

A traditional masonry or clay oven that cooks agave slowly with steam over one to three days — the old, unhurried alternative to the autoclave and diffuser.

In the glass

Slow horno cooking builds the deep, sweet-roasted agave flavour we prize. It's a hallmark of the traditional producers that top our tequila rankings.

J

Jimador / Jima

/hee-mah-DOR/

The skilled farmer (jimador) who harvests agave, and the harvest itself (jima) — trimming the spiky leaves with a sharp coa to reveal the piña at exactly the right ripeness.

Pro tip

Timing is everything: harvest too early and the agave lacks sugar; too late and it turns. A good jimador's judgement directly shapes the final spirit.

M

Mixto

Tequila made from at least 51% agave sugars, with the rest from other sugars (usually cane). It never carries the '100% agave' label and is the base of most cheap, rough tequila.

Pro tip

A bottle that just says 'Tequila' (not '100% agave') is a mixto. Put it back.

Don't get fooled

Mixto is where the 'tequila gives me a hangover' reputation comes from. The added cane sugars and lower agave content — not tequila itself — are usually to blame.

Mosto

/MOH-stoh/

The fermenting agave juice (the 'must') before distillation. Whether fibres are left in during fermentation is one of many small choices that shape a tequila's flavour.

N

NOM (Norma Oficial Mexicana)

The official Mexican standard tequila must meet — and, in everyday use, the 4-digit NOM number on every bottle identifying the distillery (NOM de Origen) where it was made.

Pro tip

The NOM number is a decoder ring. Multiple 'different' brands sharing one NOM were made at the same distillery — look it up before paying a premium for a story.

The rule

The NOM is enforced by the CRT and sets the rules for agave content, region, aging categories, and labelling.

O

Ordinario

/or-dee-NAH-ree-oh/

The cloudy, low-proof spirit produced by the first distillation pass, before the second pass refines it into finished tequila.

P

Piña

/PEEN-yah/

The heart of the agave — the pineapple-shaped core left after the leaves are trimmed. Cooking the piña converts its starches to the sugars that ferment into tequila.

In the glass

A single piña can weigh 40–100+ lbs. When you taste sweet-roasted agave, you're tasting a cooked piña.

R

Reposado

/reh-poh-SAH-doh/

“Rested” tequila, aged 2 to 12 months in oak. It keeps the agave bright while adding a light layer of vanilla, caramel, and spice — the middle ground between blanco and añejo.

In the glass

The best reposados let oak support the agave, not smother it. Fortaleza Reposado is our benchmark; El Tesoro keeps things bright and floral.

The rule

The 2–12 month window is defined by the CRT.

S

Still Strength / Distilled to Proof

Bottling tequila at the strength it comes off the still, with little or no water added to dilute it down — a hallmark of concentrated, characterful spirits.

In the glass

Distilling or bottling near full strength keeps weight and intensity. Tapatio and El Tesoro's approach shows in the density and length of the finish.

T

Tahona

/tah-OH-nah/

A massive stone wheel (traditionally volcanic) that slowly crushes cooked agave to extract its juice and fibre — the oldest and most labour-intensive milling method in tequila.

In the glass

Tahona-crushed tequila often carries a savoury, mineral, almost briny depth. It's the through-line of our favourite bottles — Fortaleza, El Tesoro, Cascahuín all use one.

Don't get fooled

The tahona is the opposite of the diffuser: maximum character, minimum efficiency. It's why tahona bottles cost more and taste like more.

Tequila (the Denomination)

Both a spirit and a protected place: agave spirit from the defined Denominación de Origen, made to the NOM. The town of Tequila, Jalisco, sits at the historic centre of it.

V

Valley (Lowlands / Tierras Bajas)

The lower-altitude agave region around the town of Tequila, with volcanic soil. Valley agave tends to yield earthier, more herbaceous, mineral tequila than the Highlands.

In the glass

Fortaleza, a Valley icon, is our shorthand for the style: savoury, peppery, olive-brine agave rather than Highland fruit and florals.
