"A big taste from a tiny place" is Creemore Springs creed. This Ontario-based brewery focuses on producing German-style beers. Here is a recipe for their Premium Lager, made using a North American lager yeast.
This is a beer formulated with some information I received about how Schlitz was brewed in 1975. I simplified this formulation by using flaked maize and specifiying that the beer be fermented at working strength, rather than using high gravity brewing.
