1) Cuervo Gold is not a premium tequila.
2) Tequila is not meant to be taken as a shot every time you drink it.
3) Your buddies from San Diego State who “totally drank the worm from the bottle of tequila,” are lying to you.
Let’s take that last part first. It is a fairly common misconception that one can find a worm in a bottle of tequila but I’m afraid unless it crawled in after you opened the bottle it’s not likely to happen. What you’re probably drinking is mescal, another type of Mexican liquor that like tequila is made from the agave plant. As mescal is bottled a cured worm, usually the larva of an agave snout weevil or the caterpillar of a certain type of moth that is found near agave plants, is added for flavor and aesthetic. For tequila it’s actually illegal to add a worm.
