In Canada, however, there are two distillers who have found a way to overcome the problems of sticky rye mashes and gummed-up equipment. Hiram Walker distillery in Windsor, Ontario, has solved the problem by using malted rye. The perfect rye-converting enzymes, of course, are made by the rye grain itself as it starts to germinate. The other, Alberta Distillers, which uses 100% unmalted rye, has developed its own proprietary strain of Aspergillus fungus that specifically converts rye starches into sugars.
I'm not saying it's impossible that WhistlePig and Jefferson's come from different sources, but I think it's unlikely.
