There really does only seem to be one beer of Belize, at least only one beer that gets any recognition.
The small but hard hiting Belikin – The Beer of Belize

The Belizeans are very proud of their Belikin, only served in small bottles, i was told this is because it could never get cold.
Brewed in a classic European lager style it uses Canadian Pilsner malt in combination with a blend of German hops to create the perfect malt hop balance. This was clearly evident whilst tasting progressed at 4.8%.
A crisp taste it went down well and there was always another one on the way. I always wondered why it was served with a serviette wrapped around the top and it was only going to be a matter of time before i found out wasn’t it ?
The Belikin gets delivered by boat to the islands off Belize and due to the salt water they can leave a small amount of rust around the top of the bottle where the metal cap is. The bottle is served with a serviette ready for you to wipe around the top before drinking, how considerate.
Other beers of Belize ? No idea……
A quick search on Google images for Belikin beer found this young chap probably enjoying his first Belikin beer –
