Tequila vs Mezcal

Tequila is technically a type of mezcal — both are agave spirits from Mexico. The differences: tequila uses only blue Weber agave with industrial cooking; mezcal uses many agave varieties roasted in earth pits. The earth-pit roasting is the chemistry inflection point.

Verdict

Tequila wins on chemistry. Blanco 100% agave tequila carries less congener load than even the cleanest mezcal because earth-pit roasting and pot distillation concentrate methanol precursors and phenolic smoke compounds.

Which one for which situation

You're prioritizing low hangover
→ Tequila
Blanco tequila scores ~4/10; even espadín joven mezcal scores ~5/10.
You want zero additives, certified
→ Mezcal
DO Mezcal prohibits additives entirely. Tequila permits up to 1%.
You're sensitive to smoke phenols
→ Tequila
All mezcal carries some smoke; sensitive drinkers report headaches even from "light smoke" mezcals.
You want maximum flavor depth
→ Mezcal
Mezcal has more terroir and character — chemistry trade-off accepted.

FAQ

Is mezcal healthier than tequila?

No, on chemistry. Mezcal carries more methanol, more phenolic compounds, and more general congener load than 100% agave tequila. Mezcal has the edge on additive transparency.

Why does mezcal hit harder than tequila?

Two reasons: (1) earth-pit roasting creates methanol precursors and smoke phenols that survive distillation; (2) pot stills retain more congeners than tequila's typical column-still finishing.

Which gives a worse hangover, tequila or mezcal?

Mezcal, at equal volumes. The phenolic compounds from agave roasting are pharmacologically active and a recognized headache trigger for many drinkers.
