Thanks for the tip about Argentina. On my way down south, I met other travelers raving about Argentina's beer. Unfortunately, I only made it as far as Colombia and then came back. Argentina will be next on the list though.
Anyways, in addition to the brewpub in Honduras, I also found one in Panama City (Istmo Brew Pub) and a brewpub chain in Bogota, Colombia, (Bogota Beer Company) both of which made tasty beer.
Also available in Colombia and Venezuela is Malta or Maltin, a soft drink manufactured by the national beer breweries, which is essentially unfermented beer. Very good, easily better than most other soft drinks.
