WLP090-San Diego Super Yeast Performance

Well I can say I just sampled my fully carbed autumn ale, and It is perfect....clean cans crisp letting the subtly of the spices be highlighted. I have quickly turned around and used this in a cream ale also. Strange that yours attenuated less, according to my notes the 001 I have used in this very recipe over the last few years has always attenuated less than this batch with 090 in it. I would tend to say, with a SG of 1.065, it is kind of luck of the draw to pitch straight from the vial and not have a stall somewhere. When you couple that with the aforementioned narrow temperature range, my guess is if you did it again but this time with a starter the results would be different. It is a super yeast in the areas of flocculation and attenuation, but resiliency.....perhaps not as much

So I've been reading a lot of negative comments on here about the yeast strain, but does anyone have something positive? Looking for some hope!

I made a 1.082 OG Stout the other day and pitched an English Ale yeast that has a max attenuation of 71%... did it for the flavor profile and it usually kicks out on day 3. 48hrs after fermentation started I pitched a 2ltr starter of WLP090 in hopes to achieve the 83%+ attenuation that's listed on White Labs website. Currently keeping the ferm temp at a steady 68F and the krausen is going strong!

Thoughts/Concerns/Comments?? Can anyone recommend something to help this finish out on a high note??

I think if you made a starter you'll be fine.

I have an update on the batch that I've posted about in this thread; post #32 and #40. The half that got 001 carbed up beautiful in 2.5 weeks. The batch that got 090 has only the tiniest of carbonation going on 7 week now. It's really pretty flat.

I'll have some time off next week and I had thought about opening each one and dropping in a few grains of us05 then recapping and give them a few more weeks. Or, since I just got some new kegs, I might just dump them all in a keg and force carbonate.

That wlp090. I'm. Not sure I'll be using it again any time soon.

I've used wlp090 twice and both times I finished at or below 1.010. There was minimal airlock activity as I started at 64-66* and it dropped to 62* (ambient temp)... I thought it was a very clean flavor and flocculates well. I will use it again, for sure.

I've used it twice. Imperial red ale both times.
First time: OG around 1.069, had massive blow off
Second: OG 1.078, no blowoff, but there was a very strong sulphur smell that had me very worried. Luckily it tasted great anyways.

It works fast and hard, don't have my notes in front of me, but it's a good yeast. I had no problem with bottles carbing up in a decent time.

Used this yeast for my IPA and pitched around 6 am yesterday. Came home to bubbles in the airlock 12 hours later! This is BY FAR the fastest and most active wlp090 has behaved for me (4-5 uses so far)! Maybe it's because my two step starter was the most successful I've made to date. Love it!

Just took a gravity reading and this yeast brought my IPA from 1.072 down to 1.008! That's 8.8% abv to you and me... This micro organism can leap fermenters in a single pitch!

I having nothing to add about the performance of this yeast. WLP090 fermented nicely while I didn't watch, measure or fret. However I thought the taste is very clean in AHS SuperCaliFugglisticESBAledocious.

Sampling my Green Warrior which used wlp090... I'm drunk off of two glasses! Very clean profile to let the hops and malt shine in a balanced IPA. I'm pretty pleased with my effort!
