That's what my own research seemed to indicate.. I'm kinda surprised I found as much as I did. I discovered Todos Santos brewing in an English language newspaper (The Gringo Gazette). Ironically when we were in Todos Santos a couple days earlier, we were a block away but just missed it.
The Cereza Fuana seemed a little more adventurous, they had a Belgian Blonde, a coffee porter, a 9% imperial stout, etc.. more like American craft. Mexicali is right on the border so they probably have a lot of American customers, and may even distribute slightly into SoCal.
They also still have pretty much a monopoly when it comes to macro beer. Grupo Modelo and Cerveceria Cuauhtémoc Moctezuma are the two games in town for lagers. Modelo does most of the ones we see in the US, Modelo, Negra, Corona etc. Cuauhtémoc Moctezuma does Dos Equis, Tecate and then some smaller brands that don't make it north, at least not to Oregon, maybe California and Arizona. Similar to the US, but the laws are stricter. I think it's a lot harder for smaller guys to get off the ground.
I think it's growing though, so it will be interesting to see how it changes. Certainly planning another trip to Baja California, that's for sure!
