Commercial Source: Source: Speculation is Red Tail, Mendocino Brewing. George Fix mentions that this is a strain of Canadian origin, and is also used for Anchor Liberty Ale. Note: previous speculation was that this was the Rogue PacMan yeast, but Rogue has said it is not, although 1) Wyeast does have a culture of the PacMan yeast and 2) the porter and stout do contain the fermentation strain.
