How to read a mezcal label

A mezcal label carries more information than a wine label, and most drinkers don't know where to look. The front of the bottle is marketing. The back is the truth. A few practiced reads will tell you more about a bottle than any producer's website will.

Start with the NOM number. Every mezcal certified under the Denomination of Origin has a NOM – a five-to-six-character code (e.g., O41X) that identifies the palenque where the mezcal was produced. Multiple brands can share a NOM – Del Maguey, Fidencio, and several others source from overlapping palenques – which is useful context. If a brand refuses to print its NOM, ask why.

Next, read the agave name carefully. 'Espadín' and 'espadín' are the same plant; 'angustifolia' is its Latin name. 'Tepextate' and 'tepeztate' are spellings for the same wild agave – the variant depends on the producer's region. 'Madrecuishe,' 'madrecuishe,' and 'madre cuishe' are all the same plant. Don't be fooled by exotic-looking variants; many are marketing refreshes of familiar agaves.

ABV decimals matter. A bottle at '50%' was likely proofed to a target. A bottle at '50.4%' was bottled at still strength – whatever came off the still that day, the producer stood by. Still-strength mezcal is the signal that a producer cared more about the spirit than the spreadsheet. Whole-number ABVs aren't disqualifying, but decimals are a credibility marker.

The maestro's name on the label tells you the producer is willing to be accountable to a specific person's work. A palenque collective without named maestros isn't necessarily a red flag – cooperative operations are legitimate – but single-maestro bottlings typically represent more careful selection.

Classification matters: 'Ancestral' means clay-pot distillation and traditional methods (stricter than 'Artesanal'). 'Artesanal' permits copper-and-clay stills with traditional fermentation. 'Mezcal' unqualified means anything that meets the minimum DO requirements – often industrial-adjacent. We cover the ancestral/artesanal categories almost exclusively; if you want to understand why, read our guide on those classifications.

What's not on the label is equally important. No aging claims? Assume joven. No 'ensamble' designation? Single agave. No village named? Treat the 'Oaxaca' origin as a postal code, not a promise. The best producers overshare; the worst hide behind an appealing bottle design and a four-word brand story.
