Mezcal is misunderstood. Most people think it’s just tequila’s rugged, campfire-scented cousin that comes with a worm in the bottle. That’s wrong. Honestly, the "worm" (which is actually a moth larva called Hypopta agavis) was mostly a marketing gimmick from the 1940s to hide poor distillation or just grab attention on a liquor store shelf. Real Mezcal—the stuff coming out of small palenques in Oaxaca, Guerrero, and Michoacán—is arguably the most complex spirit on the planet.
It’s intense. It’s ancient.
While tequila can only be made from one specific plant, the Blue Weber agave, Mezcal can be legally produced from over 30 different types of agave. This creates a massive spectrum of flavor. Some taste like green peppers. Others taste like tropical fruit or wet stones. When you take a sip of a high-end Mezcal, you aren't just drinking alcohol; you’re tasting the specific soil and the decade-plus of growth that the agave plant endured before it was harvested.
Why Mezcal Isn't Just "Smoky Tequila"
If you walk into a bar and ask for "the smoky one," the bartender will probably grab a bottle of Mezcal. But saying Mezcal is just smoky is like saying wine is just grape juice. The smoke is a byproduct of the production process. Producers, known as maestros mezcaleros, roast the agave hearts (piñas) in underground pits lined with hot rocks and covered with earth. This can last for days. It's essentially a slow-cooker in the ground.
The type of wood used—often encino (oak) or mesquite—dictates the smoke profile. If a producer uses damp wood, you get a heavy, acrid soot flavor. If they use seasoned, dry wood, the smoke is a delicate accent that lets the agave’s natural sweetness shine through.
You've got to understand the biology here. Agave isn't a cactus. It’s part of the Asparagaceae family. Because these plants take anywhere from 7 to 35 years to mature, they accumulate an incredible amount of chemical complexity. Compare that to bourbon, where the corn is grown and harvested in a single season. Mezcal is liquid time.
The Wild World of Agave Varieties
The most common Mezcal you'll find is made from Espadín (Agave angustifolia). It’s the workhorse of the industry because it’s easy to cultivate and has a high sugar content. If you're making a cocktail, you're using Espadín. It’s reliable.

But then things get weird.
Take Tobalá (Agave potatorum). This is the "king" of Mezcals for many enthusiasts. It grows wild on high-altitude rocky cliffs and is much smaller than Espadín. You need a lot of these little plants to make a single bottle. The flavor is often described as floral and creamy. Because it's hard to find and doesn't produce "pups" (offsets) like other agaves, it has to be grown from seed, making it a sustainability challenge.
Then there's Tepeztate (Agave marmorata). This plant can take 25 years to reach maturity. It looks like a giant prehistoric creature with wiggly, wide leaves. When you drink it, it often hits you with an intense burst of spice and black pepper. It’s not for beginners. It’s a punch in the face in the best way possible.
Is Mezcal Actually Better For You?
There’s a lot of chatter in the wellness world about Mezcal being a "clean" spirit. You’ve probably heard people claim it doesn't give you a hangover or that it's a "stimulant" rather than a depressant.
Let's be real: alcohol is alcohol. Ethanol is a central nervous system depressant.
However, there is a grain of truth to the "purity" argument. Traditional Mezcal is one of the few spirits that is often bottled "puntas y colas" (the heart of the run) without added sugars, colorings, or chemicals. Many mass-produced tequilas (called mixtos) are only 51% agave and 49% sugar-cane alcohol, which contributes to that "my head is exploding" feeling the next morning. If you drink a certified Mezcal Artesanal or Mezcal Ancestral, you are getting a product that is, by law, free of additives.

Dr. Iván Saldaña, a world-renowned agave expert and biologist, has written extensively about the molecular structure of agave. He notes that the complex fructans (sugars) in agave are broken down during fermentation into compounds that our bodies process differently than the simple sugars found in grain-based spirits. Still, hydration is your best friend. Don't blame the agave if you drank the whole bottle.
How to Drink It Without Looking Like a Tourist
Stop shooting it. Please.
In Mexico, they say you "kiss" Mezcal (le das un besito). You take a tiny sip, let it coat your tongue, and breathe out through your nose. This opens up the aromatics. If you slam it back with a lime wedge, you're missing the entire point of those 20 years the plant spent growing in the sun.
You'll often see it served with sal de gusano (worm salt) and orange slices. The salt is a mix of ground-up agave larvae, chiles, and sea salt. The citrus and salt act as a palate cleanser. It’s a great way to reset between different expressions, but a really high-quality Mezcal shouldn't need a chaser. It should stand on its own.
The Glassware Matters (Sorta)
You don't need a fancy crystal snifter. Traditionally, Mezcal is served in a veladora, which is a small, squat glass originally used to hold prayer candles in Catholic churches. They have a cross etched on the bottom. It’s a wide-mouthed glass, which is important because it allows the high alcohol vapors (Mezcal is usually 45-55% ABV) to dissipate so you don't just smell burning ethanol.
Another popular vessel is the jícara, a small bowl made from the dried fruit of the calabash tree. It’s porous and earthy. It feels right in the hand. It reminds you that this drink comes from the earth.

The Sustainability Crisis Nobody Wants to Talk About
We have a problem. Mezcal is too popular for its own good.
Because the plants take so long to grow, the sudden global demand has led to over-harvesting of wild agave. In some regions, biodiversity is plummeting. When people rip out wild Tepeztate or Tobalá without replanting, they are destroying an ecosystem that takes decades to recover.
Large corporations are also moving in. They see the "Mezcal boom" and want a piece of it. This often leads to industrialization, where the traditional pit-roasting is replaced by autoclaves (giant pressure cookers) to speed up production. This strips away the soul of the spirit.
When you're buying a bottle, look for labels like Artesanal or Ancestral. These are legal designations that guarantee the producer used traditional methods. Brands like Del Maguey, Real Minero, and Mezcal Vago are famous for their transparency and commitment to supporting local communities. They often list the name of the actual maker on the bottle. That matters.
The "M" Alcohol List: Beyond Just Mezcal
While Mezcal is the heavyweight champion, other "M" alcohols deserve a nod, if only to show the breadth of the category.
- Madeira: A fortified wine from the Portuguese Madeira Islands. It’s unique because it’s repeatedly heated during the aging process, which would ruin most wines. It lasts forever once opened.
- Marsala: Another fortified wine, this one from Sicily. Most people only know it from "Chicken Marsala," but a high-end, aged Marsala is a revelation when paired with cheese.
- Metaxa: A Greek spirit that’s a blend of brandy and Muscat wine. It’s sweet, floral, and very smooth.
- Midori: That neon-green melon liqueur. It’s basically liquid candy. It was launched at Studio 54 in 1978 and has been a staple of "trashy-fun" cocktails ever since.
Actionable Steps for Your Next Bottle
If you're ready to move past the entry-level stuff and really explore Mezcal, here is how you do it without wasting money on bad booze.
- Check the ABV: If a Mezcal is exactly 40% (80 proof), it’s likely been watered down significantly to meet international export "standards." Look for something between 45% and 51%. This is where the flavor compounds are most stable.
- Read the Back Label: A good Mezcal will tell you the agave species (e.g., Agave karwinskii), the village of origin, the type of oven used, and the name of the Maestro Mezcalero. If the label is vague, the liquid probably is too.
- Avoid the "Gold": Like tequila, "Gold" or "Joven" Mezcal with an amber tint that didn't come from a barrel is usually just caramel coloring. You want it clear (Blanco/Joven) or properly aged in oak (Reposado/Añejo).
- The Shake Test: Shake the bottle. If small bubbles (pearls or perlas) form and linger in the center, it’s a sign of high quality and appropriate alcohol content. If they disappear instantly, it’s likely low-proof or poorly distilled.
- Try a Pechuga: If you want to get really wild, look for a "Pechuga." During the final distillation, the producer hangs a raw turkey or chicken breast inside the still, along with fruits and spices. The vapors pass through the meat, resulting in a savory, silky mouthfeel that is unlike anything else in the spirits world. It sounds gross. It tastes incredible.
Mezcal isn't a drink you have to get "drunk" on. It’s a drink you sit with. It’s a conversation with a plant that lived through two decades of Mexican sun, wind, and rain before it ever met a glass. Respect the process, and it’ll reward you with flavors you didn't think were possible in a clear liquid.
