The Dubuisson Brewery's main brew is Bush beer. The name is actually a translation from French to English, since the Dubuisson family wanted to complete with British beers that were becoming popular in Belgium during the last century.
Bush beer is potent, containing 12% alcohol, so don't think you can have a few (like you would a Budweiser or MGD) and still be able to walk a straight line.
There are a few different styles of the Bush beer and by far the best is the Bush Noel or "Christmas" beer.
They also brew another beer called Trolls.
