I thought it was a Vienna Lager but I found one source calling it a German Pils and another a Czech Pils. I'm not fluent in Spanish or else I'd go to the Cuauhtémoc Moctezuma Brewery website to find out. Either way, it's one of my favorite Mexican beers.
EDIT: Negra Modelo, my other favorite Mexican Beer is a Vienna Lager. Still not sure about Bohemia but I do like the fact I can detect a nice malt flavor in the beer.
