Title: WLP090 San Diego Super Yeast

new strain from white labs

That was in the White Labs newsletter at the NHC.  There it is called a California Ale Yeast on steroids.  "Strong fermenter that can be done in 3 days."

Might have to try it someday.

Saw this at NHC as well. Definitely going to have to try it out

The head brewer at my LBS is going to try something with this. I can't wait to see what he comes up with

What online brewing stores are selling this?  I would love to get this in South Korea!!!

What are the odds that this is a local propietary strain, i.e. Stone?

Stone is, or is very close to WLP007 (and certainly nowhere near WLP001, which this is supposed to be very close to). Some are saying it's Port, but I dunno if I buy that.

Doesn't Stone ferment their brews at 73f?

Wouldn't surprise me. Stone also has 360 bbl fermenters and can get away with things like that.

Fermentation temps are base on the size and shape of the fermermenter.  Commercial breweries can ferment warmer than homebrewers because of pressure on the yeast in the cone surpressing esters and fusels.  Not sure if it is Stone's yeast or not, just a theory.  I know White Labs propagates Stone's yeast.  Could be another local yeast, Port, Alesmith, etc. Ballast Point may be the logical option since that is how Chris White got started, now that I think about it.

I dunno, it seems to me that the characteristics of this yeast are closer to an English strain of yeast than Chico.  Especially with the flocculation being medium to high.  That is why I was thinking Stone because WLP007 is like WLP001 and WLP002 had a child on Ritalin.  It generally attenuates out to 80% in 3 days, ferments in the high 60's, and flocs out like a brick in the fermenter, which it sounds like WLP090 does as well.

Stone told me that they basically started off with WLP002 and to use that if I want to replicate their brews... I haven't used 007, so I can't say for sure... but they've been pretty good about giving up recipe info aside from AB...

Nope, it was actually my feeble attempt to bash Arrogant Bastard, which I think is absolutely vile and disgusting, and easily the worst beer they make.

I had AB at the brewery during NHC week and I was astonished to find out that I really liked it.  Prior to this, I had always hated it which makes me think that there packaging is wanting and causes lots of oxidation once it is shipped in the big bomber bottles.

AB is my all-time favorite beer and I look forward to having it fresh at the brewery next week.  Only had it in the bombers, can't wait to have it on draft!

As a native San Diegan, I've had it at the brewery several times, and while I'll admit that it's better, I still don't like it. Taste like they just steeped a bunch of C120 and boiled it with Chinook.  ::)

Ok, you're a wierdo.  ;D

While you're there, drink something good - like Ruination. Oh and stay away from Greg, he's the definition of Arrogant. :P

So what is so "super" about this yeast? Some sort of Piranha type yeast? :) Done in three days- that's most fermentations. Is it ready to drink in three days?

As far as AB goes I liked it at $3 a bottle. At $5 not so much. It changed after the hop-crisis in my opinion and isn't as good.

In total disclosure, it was the final beer of the tour and had already "sampled" several pints of their other offerings before I ordered the Bastard. ;D

Title: Re: WLP090 San Diego Super Yeast
Post by: gmwren on August 11, 2011, 12:46:12 PM
According to Dr. White, it is a variant of the California Ale Yeast strain they've been developing for 3-4 years. It is not from a commercial or local brewery and is named "San Diego" because it was introduced at the homebrewers conference there.  It is supposedly similar, but complimentary to the California strain. It is clean, neutral, ferments high gravities, and not overly estery.

That being said, has anyone used it? My concern is the narrow temp range as one could start it at 65F and a high gravity, rapid fermentation could easily boost the temperature well above 68F. Anyone push either end of this one yet?

WLP090
Optimal Fermentation Temperature: 65-68F
Attenuation: 76-83% +
Flocculation: Medium-High
Alcohol Tolerance: High

WLP001
Optimum Fermentation Temperature: 68-73°F
Attenuation: 73-80%
Flocculation: Medium
Alcohol Tolerance: High

thanks for the info gmwren.

I bought some last week and plan to use it in a Green Flash IPA clone.  I still plan to pitch at 60 and ferment at 62-64, for much of the reason you commented.  optimum usually means for yeast performance not for the best beer.

I'm most concerned about the high expected attenuation.  Looks to me like liquid US-05...

The description is right.  I brewed a standard malty amber and it is clean and well attenuated.  I say it is somewhere between 001 and 002.  It flocs really well and has cleared up nice and brilliant after only two weeks in the keg.  I fermented on the high side (~68F) and got a very clean beer.  I am currently fermenting an ordinary bitter with the second generation of the initial tube.  It smells good out of the airlock so far.

Glad to hear you're making that Green Flash IPA. Its such a good beer! I'll be trying this yeast on my next batch of GFWCIPA as well. Let us all know how it turns out.

I'd be happier with a WLP655 on steroids.....make my sour beers in half the time!

so far, its awesome!  dropped from 1.070 to 1.016 in <10 days and it might be done - can't tell if the backpressure in the airlock is just degassing or if there is still a little activity - will check again on sunday. 

the taste and aroma of the sample was divine - looking forward to this one.

update - got down to 14 at kegging, which is perfect for this recipe.

I love this yeast - I can easily see it replacing 001 in the future for me, though I need to try it out on a few other styles to be certain - just a great performer - flocs very well (only in the keg 6 days and is almost brilliant) and is clean/neutral in flavor.  hops really shine through.  could not be happier.
