The Beerita is basically a Modelo Tall Boy with tequila added, plus salt and lime around the rim of the can. And all that can really be said about this drink is you're either ready for the Beerita, or you aren't.
1 Modelo Tall Boy
1 oz. (30ml) Tequila
1. Lime the rim of can and dip into salt.
2. Open can and take a sip before squeezing lime juice and tequila inside.
