The Mexican NOM defines six classes of mezcal. Yet one class dominates so completely that the others barely register. An exploration of 2,300+ bottles reveals why mezcal’s soul lives in the unaged spirit — and why the barrel is almost irrelevant.
Below, every small square represents roughly 1% of all mezcal bottles in our database. Find the colored ones — those are everything that is not Joven.
The pattern in our review database mirrors official COMERCAM production data almost precisely. In 2023 certified production, Blanco/Joven accounts for 97.37% of all mezcal produced. Abocado con makes up 1.35%, and Destilado con (the official name for Pechuga) just 1.28%. Reposado and Añejo are so rare they barely warrant their own line in the data.
Mexico’s NOM 0070 defines six official clases of mezcal. Each represents a different relationship between the spirit and time. Here is how each maps to real bottles in the market:
In whisky, bourbon, and tequila, aging generally signals prestige. More time in wood means a higher shelf and a higher price. In mezcal, the community tells the opposite story. The unaged and glass-aged styles consistently outperform barrel-aged ones in ratings.
Aged in Glass leads at 4.11 — higher than any barrel-aged style. Ensamble sits at 3.94. Joven at 3.84. Then there is a cliff: Añejo drops to 3.33, Abocado to 3.28, and Reposado bottoms out at 3.13. The barrel does not elevate mezcal — the community believes it diminishes it.
This is not just about averages. Look at the shape of the rating distributions:
Joven and Aged in Glass are heavily right-skewed — most bottles cluster in the 3.5–5.0 range. Reposado skews the opposite direction, with most bottles rated below 3.5. The barrel, it appears, is where mezcal character goes to dissolve.
ABV tells its own quiet story. Traditional mezcal is bottled at proof levels that would make most spirits producers nervous. But barrel aging brings it down — conforming to smoother, more commercial expectations.
Perhaps the most revealing metric: how many distinct maguey varieties appear within each class. Mezcal’s magic lies in the astounding biodiversity of agave species used. Over 50 named varieties appear in the database. But that diversity is radically uneven across classes.
The disparity is extreme. Joven celebrates 101 named maguey varieties. Barrel-aged classes use just 6 each. And the story deepens when you look at which magueys dominate the barrel:
Of 47 Reposado bottles linked to a named maguey, 38 use Espadín — that’s 81%. For Añejo, 27 out of 36 are Espadín — 75%.
Oaxaca is the undisputed heartland of mezcal, responsible for over 90% of certified production. But the barrel-aged classes are even more concentrated there, while Joven production spreads across Mexico’s diverse landscape.
Joven’s geographic spread mirrors its philosophical breadth: 16 states produce Joven mezcal, each contributing distinct terroir, agave varieties, and distillation traditions. Durango brings Cenizo agave and Duranguense stills. Guerrero contributes its own wild magueys and unique clay-pot methods. Reposado and Añejo, by contrast, are overwhelmingly concentrated in Oaxaca — reading more like a commercial operation than a living regional tradition.
Every data point in this analysis converges on a single thesis. The dominance of Joven is not a market quirk or an accident of economics. It is the logical expression of mezcal’s core identity.
