CND is owned by Miller Brewing Co., which in turn is owned by a South African company I believe. Brahma is made by Ambev (the largest brewery holder in the world). They recently purchased Anheuser-Busch, so I wonder if they'll try to take yet another stab at introducing Budweiser into The DR. Last time didn't go so well...
Presidente is king in The DR. Nobody knows the market like they do...they've been challenged left and right over the years and always come out on top. I thought Ambev with their deep pockets would be the ones that would give them a run for their money, but alas after a few years Brahma is relegated to a cheapo second rate beer (in the eyes of Dominicans) that people only buy because of highly discounted prices (i.e. 3 for 100 pesos).
I was wishing they succeeded and continued to introduce many different beers (the more the merrier). For instance I liked Quilmes, but you can't find it anymore. Was hoping I could find Stella-Artois anywhere, but again you can't find it in the local colmado. Presidente just has a hold on the Dominican Psyche that's extremely hard to break.
The one thing that IS changing is that more and more people are drinking wine, vodka, mixed drinks, etc...it used to be it was just beer, rum and if you could afford it some kind of Whisky.
