The BEST Canadian pilsner in fact the BEST Canadian beer. Originating from Toronto, brewed to the highest of german standards. Crisp and clean in taste with a grassy aftertaste. First founded under the name of Three Fired Guys which if you look at a bottle you can still find TFG. The crowning glory of this brew is that it is made with all natural ingredients ( only four in fact) and does not use high gravity brewing techniques that are the standard for most larger breweries, this means hangovers do not occur after drinking large quantities. The Brewery itself is located in an old train turn station which is quite fitting because of the name yet this is not the inspiration for the name. steamwhistle.com The Good Beer Folks!
