Overview
About Mezcal
Mezcal is not one drink the way tequila is.
Tequila must come from blue weber agave; mezcal can be made from any of dozens of agave species, from the workhorse espadin to slow-growing wild plants like tobala and tepeztate, and each brings a different flavour before a distiller does anything. The smoke everyone notices is a production method rather than an additive: the hearts are roasted for several days in a conical pit dug into the ground, lined with hot rocks and wood and buried under agave fibre and earth. What follows is just as relevant to how it grades. Most mezcal is crushed under a stone wheel, fermented in open wooden vats on whatever wild yeast is in the air, and distilled in small copper or clay pots that keep far more of the congeners than a column still would. That is the reason mezcal grades C for histamine and C for tyramine, above a filtered neutral spirit, while grading A right across gluten, lactose, dairy protein, every FODMAP column, nickel, glutamates, oxalate and nightshade.

How Mezcal scores
Watch for
What trips people up
- Histamine C and tyramine C, both moderate. Wild open-vat fermentation and a pot still that is not built to strip congeners are what put mezcal above vodka here, and reposado and anejo expressions add barrel time on top of that. Blanco or joven is the gentler end of the category
- The bigger histamine issue with any spirit is not what is in the glass. Alcohol suppresses diamine oxidase, the enzyme that clears dietary histamine, so a mezcal drunk alongside aged cheese, cured meat, anchovies or wine can change how you handle the entire meal rather than just adding its own moderate load
- Clean on FODMAPs, and that surprises people who know agave is one of the richest natural sources of fructans. Days in a roasting pit convert those fructans to simple sugars, fermentation consumes them and distillation carries over none of what remains. Agave syrup in the cocktail is the opposite story and is a high fructose sweetener in its own right
- The smoky character is phenolic aroma picked up from the pit before fermentation ever starts, and carried over the still. It does not put mezcal in the same bracket as smoked or cured foods, which earn their grades from nitrites, amines and long curing rather than from smoke aroma
- Sulfite B is modest and incidental, but pro-inflammatory D and a poor fit for both DASH and Mediterranean patterns are worth naming. That is the ethanol talking, and it is true of every spirit on the shelf regardless of how artisanal the production is

FAQ
Common questions about Mezcal
Is mezcal high in histamine?
It grades C, moderate, alongside tyramine at C. That sits above a heavily filtered neutral spirit and reflects spontaneous fermentation in open vats plus pot distillation that keeps a lot of congeners. For someone with histamine intolerance the practical point is broader than the grade: alcohol of any kind inhibits the enzyme that breaks down dietary histamine, so mezcal can amplify a reaction to the food around it. If you are drinking it anyway, an unaged joven with a small amine load on the plate is the gentler version of the evening.
What actually makes mezcal different from tequila?
Three things. Species: tequila is blue weber agave only, while mezcal is made from any of a wide range of agaves, wild and cultivated. Cooking: tequila steams its agave in ovens or autoclaves, mezcal roasts it in earth pits under wood and hot rocks, which is where the smoke comes from. Process: mezcal is typically pot distilled in small batches after an open, wild fermentation. The first two are flavour, the third is what nudges the amine grades up.
Is mezcal gluten free?
Yes, and not on the strength of the distillation argument. Agave is a succulent, not a cereal, so no gluten grain is involved at any stage and it grades A. The realistic risks are elsewhere: flavoured or cream mezcal liqueurs, pre-mixed cocktails and rimming salts or spice blends served with it, several of which are worth checking for wheat-derived ingredients.
Is the worm in mezcal traditional, and does it change anything?
No on both counts. The larva is a mid-twentieth century marketing idea rather than a piece of heritage, introduced in the late 1940s to make bottles stand out against booming tequila exports, and brands built around it were being trademarked from 1944 onward. It has no traditional or ceremonial role and no effect worth reporting on a trigger journal. Bottles sold with it are a specific commercial style, not a mark of authenticity, and most respected mezcal is sold without one.
