What Tequila Has The Worm

So, you’ve seen it. That one bottle of tequila sitting on the back bar, the one with a weird, pale worm floating at the bottom. And you’ve probably thought, “Wait, is that… normal?” Or maybe you’ve heard a friend brag about “eating the worm” after a shot. Let’s get one thing straight right away: the worm is not a gimmick. It’s actually a tradition, and it’s way more interesting than you’d guess.

The truth: only one type of tequila has the worm

Here’s the first surprise: real tequila never has a worm. That’s right. If you’re sipping a bottle labeled “100% Blue Weber Agave Tequila,” you’ll never see a worm inside. The worm lives only in mezcal, tequila’s smoky, rustic cousin. And even then, it’s not in just any mezcal—it’s specifically in a style called “mezcal con gusano.” So why do we call it a “tequila worm”? Blame marketing. In the 1950s, a clever brand dropped a caterpillar into their mezcal bottles to stand out. It worked. Everyone started calling it the “tequila worm” and the myth stuck.

But… what kind of worm is it, really?

It’s not a worm at all—it’s a caterpillar. Specifically, the Hipopta agavis moth larva, which lives inside the agave plant. Think of it as the plant’s secret resident, munching on the same agave that gets turned into booze. That’s pretty wild, right? The same plant feeds the spirit and the creature swimming inside it. It’s like a little agave-based ecosystem in a bottle.

Some bottles even contain a salt-coated caterpillar on the rim, instead of floating in the liquid. But the classic version? You get a worm at the bottom, staring back at you like a tiny, boozy time capsule. It’s weird, sure, but also kind of cool—like finding a fossil in your drink.

Why would someone put a caterpillar in alcohol?

That’s the million-peso question. First, it’s a tradition. Indigenous people in Oaxaca, Mexico, have used the agave worm in rituals and as a source of protein for centuries. Adding it to mezcal was a way to honor that history. Second, the worm is said to change the flavor. As it sits in the bottle, it releases oils and amino acids that can soften the smoky bite and add a subtle, earthy richness. It’s like aging whiskey in a barrel, but with a caterpillar acting as the barrel.

Mezcal Worm in a Bottle Yields Surprising DNA Results

And let’s be honest—it’s a party trick. You buy a bottle with a worm, you’re supposed to notice it. It’s the booze equivalent of a loud Hawaiian shirt. But here’s the fun part: in Mexico, eating the worm is actually seen as a rite of passage. Some say it gives you courage, others say it enhances the buzz. Scientifically? It’s just a crunchy, salty snack. But hey, if it makes you feel like a legend for a minute, why not?

Is it safe to eat?

Totally. As long as you’re not allergic to insects (and most people aren’t), go for it. The worm is preserved in alcohol, which kills any bacteria. It’s also packed with protein—about 40% by weight. Think of it as a weird, mezcal-infused protein shot. Just don’t expect it to taste like a gourmet meal. It’s mostly a texture thing: chewy, salty, and a little bitter. Some people love it. Others spit it out. There’s no wrong answer.

What is a Tequila Worm? Should you eat it? And why is it there

Which brands actually have the worm?

You can’t just grab any mezcal. Look for these classics: Monte Alban and Bruxo are the big names. They’re affordable, widely available, and proudly display a fat worm in every bottle. There’s also Xicaru, which adds a smoky, earthy kick. If you see one of these on the shelf, you’ve found the real deal. Avoid cheaper knock-offs labeled “tequila worm” that are just normal tequila with a plastic worm—those are just gimmicks. Stick with 100% agave mezcal con gusano.

Final question: should you try it?

Why not? It’s a conversation starter. You’ll never forget the night you ate a worm from a bottle of booze. Plus, it’s a small way to connect with a centuries-old Mexican tradition. Just remember: real tequila doesn’t have the worm, but real mezcal might. So next time someone hands you a shot with a caterpillar, don’t freak out—sip, crunch, and smile. You’re now part of a very strange, very delicious club.
