As far as I know there have only 3 brewing licenses issued in the whole country... The cervezeria nacional (pilsen, imperial, bavaria, rock ice, etc), K&S (closed their restaurant and now sell a couple of their beers through places like ToT), and some places near Limon that isn't even operating right now.
Sucks for people like me who like ales, they don't even get imported. My favorite beer available here is the only ale that does make it, Red Seal Ale from california, which is like 1600 colones at Auto Mercado.
