Groelsch is a fantastic Dutch beer. But if you like the whites, blondes, and wheat beers, there is (as I mentioned) Blanche de Chambly from Quebec...Its beautiful. I drink it with a lemon on occasion. There is also the Belgian: Chimay White which is not as smooth but still worthy of a try. Another, more mainstream brewery in Canada recently put out Rickards White (in addition to Rickards Red, Honey Brown, Pale, etc. ) and served it with an orange slice. Not bad.
Petrus Blonde is another Belgian and may be particularly hard to find, its a golden Blonde but so smooth and full flavored.
FINALLY....
Though unless you live near it or vacation there, my favorite smalltown brewery is Muskoka Brewery in Bracebridge Ontario...
