A tequila label is denser than it looks. Behind the type and the seal sit a few marks that actually tell you what is in the bottle. Learn those, and you stop guessing from the front of the glass alone.
Start with 100% agave — or the Spanish 100% de agave. That line means the spirit is made only from blue Weber agave sugars. Without it, the rules still allow other sugars in the ferment, which is a different drink even when the bottle says “tequila.” If the house wants a clean reading of agave, this is the first filter.
Next, find the NOM — a short number, often near “NOM” on the back or shoulder. It names the registered distillery where the spirit was made. Two brands can share a NOM; one brand can move NOMs over time. The number is not a quality score. It is a map pin: who distilled it, and where that paperwork lives. When you care about provenance, the NOM is the honest hinge.
Then read the age class. Blanco (or plata) is unaged or only briefly rested — the closest view of the agave. Reposado has spent at least two months in oak; añejo, at least a year; extra añejo, at least three. The words describe time in wood, not a ranking of better and worse. Barrel softens and spices; it also covers some of what the field put in. If you want the plant clearest, begin with blanco. If you want wood in the conversation, reposado and añejo are the next chapters.
Ignore the noise that does not help: cartoon stories, “premium” with no definition, gold that is only colour. Look for the three that hold: agave purity, NOM, age class. Together they give you a bottle you can place — plant, place of distillation, and time — before the first pour.
At House of Diwani we treat the label as part of craft literacy, not fine print. A good bottle earns the words printed on it. Read those words first; the glass will finish the sentence.
