I brewed 2 beers recently with this yeast. The first was a Session American IPA and the second was an imperial stout at 1.097 using the yeast cake from the previous. For the IPA at 65F, It finished in 3 days and cleared up in 7 and was ready to keg. Dry hops went in for the final 4. It made a very clear beer and didn't contribute anything flavor wise, although the hop aroma may have been muted in comparison with IPAs I've brewed with US05. For the stout at 65F, It fermented aggressively for the first 2 days, blowing off almost a quart of yeast and wort until it reached 1.035. Then I had to raise the temp to 68 and shake it up for it to finish at 1.025. Too much other stuff going on in the stout to really tell what it contributed.
My thoughts: A clean fast fermenting yeast that clears nicely. Didn't perform as well as I expected at high gravity. I probably won't use it again because S04 has performed similarly for me and I prefer dry yeast.
