I picked up a couple vials of this and used it for 3 brews:Extra Pale Ale - a hopped-up session beerAmerican Pale Ale - very hopped up and dry-hopped versionOatmeal Stout - a somewhat high-gravity but lighter color (for a Stout) versionHere are the Stats on this yeast from White Labs:Attenuation 71-76%Flocculation: Medium to HighFermentation Temp: 66-70 (ideal range)Alcohol Tolerance: MediumMy Stats with this yeast:Attenuation 70% (EPA, pitched one vial/5 gallons wort), 72% (APA, pitched slurry) and 76% (Stout, pitched slurry)Flocculation: Observed very high flocculation upon completion of fermentationAlcohol Tolerance: Got high attenuation according to White Labs published range with the Stout which was 7.0% ABVFermentation temp: All 3 fermented around 67-68 FObservations: Lag times were about 12 hours for each brew. Fermentation was steady for 5 to 7 days with airlock activity continuing up until day 10 for all 3 brews. I did not use foam control or blow-off tubes and had no problems. There is a visible top-cropping fermentation action with this yeast. Flocculation is fairly complete upon attenuation. Bottle conditioning took one week for all 3 brews. Tasting: All three brews had a base of Marris Otter Pale malt and different combinations of American hops. There is a nice but not overpowering fruity profile with aromas of stone fruit like peach. The warm-bread malt flavors/aromas of the MO malt came through very nicely. In the oatmeal stout there were a lot of coffee/esspresso notes from the Roasted Barley and Black Patent malts. The APA had a wonderful balance of crystal malt sweetness and bright smooth hop bitterness and aroma. In general, this yeast seems to develop well-rounded flavors without leaning too much towards either the malt or the hops. The one thing I don't notice is a lot of dry-hop aroma in the APA so I will just go with late/whirlpool hop additions in the future.Summary: I highly recommend this strain. Very easy to brew with. Only downside is it's currently a Platinum Strain so only available in January and February.
