I used it several times for my IPA and always finishes clean and allows the hops and malt flavors to come through cleanly. Last weekend i brewed a higher-gravity dIPA and was pleased to see fermentation begin within 10 hours (no starter) and at a fairly low temperature (my basement is about 65 degrees this time of year). Vigorously fermenting despite the temperature. I really like this yeast.

Have used this strain for many batches of beer. Always a solid performer.



By: Mike from UK | Date: Dec., 22nd 2015 | Beer(s) Brewed: Hop-burst IPA


I'd avoided this strain for too long having had a couple of bad experiences with its dried equivalent, but this made a superb clean IPA with the hop flavours really firing. Didn't over-attenuate either, went from 1056 to 1013 (mashed at 68C/154F)

Don't worry about the flocculation if you can cool. I cooled to 10C / 50F after 10 days in primary and it dropped like a brick. Also settled well in Bottle conditioning (with help from a bit of gelatin)

Looking forward to using this on more beers.



By: Shayne | Date: Oct., 21st 2015 | Beer(s) Brewed: APA/IPA


I've used this yeast strain many times with excellent results. This is the perfect strain for APA/IPA where hops and malt profile flavor accentuation is a must. The strain completes a majority of activity within the first 5 days, and leaves an extremely clean flavor with excellent flocculation (clear final product without fining agents.) This strain is superior to any other that I've used for west coast style pale or IPA. It does have a fairly high attenuation, frequently leaving a 1.008 FG in the 152-153 mash temp range for a modest APA with an OG of 1.050-1.060.
