The Old Bald Guy couldn't have said it better. Mexico. I've been to Mexico a few times, and have thoroughly enjoyed each and every minute there. First in Cozumel, we stayed at El Cozumeleno; then several years later, at the Riu Palace Las Americas in Cancun. Both were all-inclusive hotel resorts, so I'm thinking you're getting my drift. If not, I'll spell it out--all the beer and tequila you can drink (as well as food, if you are interested.)
So I am pretty sure, if I remember correctly, that El Cozumeleno served Dos Equis as its main tap beer, so I had A LOT. The Riu chain served Corona though, so I guess I'll get back to that.
Dos Equis is brewed in Monterrey, Mexico by Cerveceria Cuauhtemoc Moctezuma S.A. de C.V. If you had to equate this beer with one from the US, this is the Miller Light of Mexico. It's funny that Miller and Dos Equis aren't both owned yet by the same beer behemoth SABMiller.
Finally, the taste. Decent fare, pretty light lager, smooth, good taste. In my opinion, it's a notch above the mass produced beers of the US because of the flavor.
By the way, Dos Equis means Two X's, in case your Spandicapped. And that's your Spanish lesson for the day. I'm guessing that I'll have 8 or 10 more lessons today--goes with the territory for a guy from Pennsylvania who hasn't learned Spanish after being married to a Colombian woman for 12 years. Pray for me!
