It's good that they are finding a big market in the US. Stella Artois, Franboise Lambic, Moinette, Duval are some of the Belgian beers I like and available in the US. I can get Stella in a 12 pack at a store in town.
A lot of good Belgian beer have a high alcohol content of around 7%~9% which makes it understandable why people are starting to drink less of it.
