Agave: Tequila vs. Mezcal
Two spirits from the same plant family, made in profoundly different ways. What separates them, and how each behaves in a cocktail.
Tequila is a mezcal. That sentence surprises many drinkers, but it is legally and technically true: mezcal is the umbrella term for any Mexican distillate made from cooked agave, and tequila is the specific subset made from blue Weber agave in and around the state of Jalisco. Every tequila is a mezcal; not every mezcal is a tequila.
The categories diverge sharply from there, in the plant, the cooking, the distillation, and — most importantly for cocktails — the flavor.
Tequila
Tequila is made exclusively from blue Weber agave (Agave tequilana). The plants are steamed in large industrial autoclaves or, at more traditional distilleries, in brick ovens called hornos. The cooked agave is milled, fermented, and typically double-distilled in copper column or pot stills.
The regulatory categories describe wood contact: Blanco (unaged or under two months), Reposado (2–12 months in oak), Añejo (1–3 years), Extra Añejo (over 3 years). Cristalino tequilas are aged and then charcoal-filtered to remove color, a marketing category that softens flavor for premium pricing.
Mezcal
Mezcal can be made from dozens of agave varieties — espadín is the workhorse, but tobalá, tepeztate, madrecuixe, and others appear on serious mezcal labels. Traditionally, the agave hearts (piñas) are roasted for several days in earth pits lined with hot volcanic rocks and covered with wood.
That roasting is what makes mezcal smoky. The smoke is not an additive; it is baked into the piña before it is milled and fermented. Most mezcal is distilled twice in small copper or clay pot stills.
How they behave in a cocktail
Blanco tequila is grassy, peppery, and vegetal. It is what belongs in a Margarita, a Paloma, and a Tommy's Margarita (tequila, lime, agave syrup — the ratio-only cousin).
Reposado is rounder and softer and works well in stirred drinks — a tequila Old Fashioned, an Oaxaca Old Fashioned (with a splash of mezcal), or a tequila Manhattan.
Mezcal has to be dosed carefully. A full pour will overwhelm most drinks with smoke; a half-ounce split with tequila (as in the Oaxaca Old Fashioned) gives smoke as a top note over the tequila's base.
Reading a label
'100% agave' means the spirit was fermented from agave sugars alone. 'Mixto' tequila permits up to 49% added sugar — corn or cane — and is generally a lower-quality product that produces a rougher cocktail.
For mezcal, look for the producing family and village name on the back label. A single-producer artisanal mezcal is fundamentally different from a mass-market bottling that carries the same category name.
Frequently asked
- Which tequila for a Margarita?
- A 100% agave blanco. Reposado adds oak that competes with the lime; añejo is wasted in a shaken drink.
- Can I substitute mezcal for tequila?
- Not straight across. Mezcal reads twice as strongly. Start by splitting: half mezcal, half tequila, and adjust from there.
- What about sotol and raicilla?
- Both are Mexican agave-adjacent spirits (sotol from a different plant genus, raicilla from other agave species). They deserve their own primer; briefly, treat them like mezcal.
