[S. cerevisiae]

Are you sure the UFO strain is the same as their core beers? Their core beers taste like London Ale to me, but I've always suspected that the UFO line was a different strain.

Harpoon uses the same strain for all of their beers.  It's a powdery strain.  My bet is that it is a one of the common English strains that mutated over time.

With that said, the mystery U.C. Davis strain that I pitched three weeks ago appears to have it all, good flavor, good attenuation, and high flocculation.   However, a sample size of one does not tell us much.

Yeah, harpoon does use the same strain for ales, lagers and wheats. They just handle the strain differently. Which may be why all their beers taste the same. Not to mention boring.
