My impressions with this yeast ... Has spicy, earthy esters, especially in the aroma. Pretty clean ester flavor, slightly more esters than WLP001. Mutes the hop flavor slightly, but leaves a crisper, lingering hop bitterness on the back end. Definitely more flocculant than WLP001 -- when I use Cali ale I usually end up filtering, definitely not necessary with this yeast. When the beer is young, it will have an oniony flavor (seems to be the esters), but that seems to age out quickly. Accentuates the "cat piss" flavor and aroma of some American "C" hops.

Overall, it is most similar to Wyeast 1272. I still prefer Wyeast 1272, American Ale II, over this yeast for the beers I have sampled made with it (APA, Lake Walk), but I think it would be an excellent choice for a hoppy American IPA. I will give it another shot next time I brew up one of my IPAs.

In addition to American IPA, I think the ester profile and attenuation of this yeast would be ideally suited to an American Stout or Robust Porter style beer. The alcohol tolerance is listed at 10%, pretty low, so I would avoid using it on any of the imperials. In practice the alcohol tolerance of WLP001 is much greater at about 16%.

Not having much luck with this yeast. Made a nice big starter(750ml) as per usual, used yeast nutrient in the boil.

Over 24 hours to get going, which is slow by my standards. Last 3 batches on my new setup all were ripping after 12, and completely done within 4 days. On day 5, it's still at .024, crap. Krausen is almost dropped, but still a thick skin on top. I don't get it.

That's what I was expecting, I swear it left a heap of yeast in my starter, more than i've ever seen. Very disappointing thus far.

I have two IPAs entered into a state BCJP comp this weekend - 10 gallon batch, split into two fermenters: one with greenbelt, one with WLP001.

I'll post the judges tasting notes...

Well, I know what I'm brewing next- an IPA using Greenbelt. My father-in-law's lived in Austin for going on 45-50 years now, he's a huge IPA fan, and their house is like a quarter-mile from the Barton Skyway greenbelt entrance.
