Tequila and mezcal: agave, NOM and smoke on the label
Mezcal doesn't smell like smoke by accident — it smells like a pit in the ground. How to read the label, what NOM means and why añejo is not always better.
That bottle with the worm in the bottom you saw in some bar in the nineties wasn't tequila, and probably wasn't decent mezcal either. It was a trick for tourists. The real story of agave begins when you realize that between industrialmixtojuice and real100% de agaveof distillates, the abyss is deeper than between the dreamy brandy from the shed and the premium cognac.
Tequila and mezcal are cousins, not twins. Both are made from agave, both have a Mexican origin protected by the label, but they are separated by one crucial difference in technique that can be felt already at the first smell:smoke. Once you learn to read the label, you never buy blindly again.
Agave is not a cactus, and that changes everything
The first misconception to bury: agave is not a cactus, but a succulent from the asparagus family that grows between seven and twenty-five years before ripening. the heart of the plant,drink, weighing up to eighty kilograms, that's all. It contains sugars that become alcohol after roasting and fermentation.
By law, tequila is made exclusively from one variety —blue agave (Agave tequilana Weber)— and only in five Mexican states, with Jalisco as the heart of the region. Mezcal is more liberal: it allows over thirty varieties of agave, among which it dominatesEspadín, and wild varieties likeTobaláandTepeztatethey bring a complexity that doesn't exist in tequila.
The key difference in taste is born in the country, literally. For tequila, piñas are steamed in industrial autoclaves or brick ovens. For traditional mezcal, the piñas are baked inearth pits lined with volcanic stones and wood, for days, under the soil layer. Smoke from there. It's not an afterthought — it's earth, charcoal, and wood written into the heart of the plant. He who looks for that note on the label is looking for a wordartesanalorancestral.
NOM: a number that reveals who actually made the bottle
It says on every legitimate bottle of tequilaNOMfollowed by a four-digit number. It's not a marketing code — it's the distillery's registration number with the Mexican regulatory body (CRT for tequila, CRM for mezcal). The same NOM number on two different labels means that both drinks came from the same distillery, no matter how different the prices.
This is the most powerful information on the bottle and the least known. When two brands share NOM, you pay the difference in design and marketing, not necessarily in liquid. Second rule: look for the caption100% de agave. If it is not there, it is in questionmixto— tequila that is allowed to have up to 49% sugar from cane or corn. The headache that the world attributes to tequila almost always comes from that very place.
| Label | What does it mean | What is the customer looking for? |
|---|---|---|
| 100% de agave | No added sugars | Mandatory |
| NOM + number | Distillery register | Compare brands |
| mixto | Up to 49% other sugar | Avoid |
| artesanal / ancestral | Traditional making (mezcal) | For a smoky character |
Blanco, reposado, añejo: why older is not always wiser
The aging categories are the same for tequila and mezcal, and this is where most people make the mistake of thinking that añejo is automatically the peak. It's not. Each category serves a different purpose.
Both are made from agave, both have a Mexican origin protected by the label, but they are separated by one crucial difference in technique that can be felt already at the first smell: smoke .
Blanco (silver)is a distillate without aging or up to two months in steel. Here you hear pure agave — herbal, peppery-citrus, mineral. For cocktails and for those who want to understand the variety, blanco is the truth without make-up.Reposadoit is aged from two to twelve months in oak and acquires the color of straw and notes of vanilla and caramel, but the agave still breathes under the tree.Añejoit spends from one to three years in barrels up to 600 liters — rounder, darker, closer to whiskey, but there is a risk that the oak will swallow the agave.Extra añejois over three years old.
Our conclusion after many tastings is simple: you almost always go for mezcaljoven (white), because the barrel kills that smoky, earthy character that makes you drink it in the first place. For tequila, reposado is the safest buy — just enough character, without too much oak. The logic is the same as the codesake where ginjo does not automatically mean better than junmai: category describes style, not rank.
How to drink and how not to drink
Salt, lemon and shot are an introduction to a bad night and an insult to a good spirit. You drink quality tequila and mezcalclean, at room temperature, from wide glasses, with small sips. In Mexico, mezcal is served with orange sprinklessal de gusano— salt with ground agave worm, which enhances the earthy notes. Blanco tequila is at the same time the basis for a timeless cocktail: the real oneMargaritais tequila, lime and triple sec, nothing from a ready mix.
The same rule as code applies to temperaturehomemade aperitifs from the terrace— cooling deadens the aroma, so we never serve a good distillate from the freezer.
Hidden gems: what only someone who has searched knows
First -pechuga mezcal. It's mezcal distilled a third time with chicken or turkey breast suspended in a cauldron, along with fruit and spices. It sounds absurd, but the result is a silky, rounded distillate made only for special occasions. If you see it, buy it.
Second — pay attention to the agave variety printed in fine print on the back of the mezcal.Tobalá, a wild variety that grows in the shade and matures for twenty years, gives a floral, almost tropical profile without heavy smoke; the complete opposite of expectation.
Third — inscriptionson of abocanteor100% agave, additives prohibited. Industrial tequila can legally contain up to 1% additives (glycerin, color, syrup) without declaration. The best small producers explicitly deny this on the label. That little inscription is worth more than any medal on the bottle.
Questions & answers
short and to the point- What is the difference between tequila and mezcal?
- Tequila is made only from blue agave and piñas are steamed, so there is no smoke. Mezcal uses over 30 varieties of agave, and the piñas are baked in earthen pits, which is where the characteristic smoky flavor comes from.
- What does the NOM number on a bottle of tequila mean?
- NOM is the four-digit registration number of the distillery. If two different labels have the same NOM number, they both came from the same distillery — the price difference is then mostly marketing.
- Is añejo better than blanco?
- Not necessarily. Blanco shows pure agave, and añejo gets notes of oak and vanilla but can lose the character of agave. Joven is almost always recommended for mezcal because the barrel stifles the smoke.
