WLP090 San Diego Super Yeast

[euge]

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.

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.

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.  :

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

LOL. Does it fight crime or just bad sugars gone awry?

So what’s the deal with this yeast?  Anyone used it yet?

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?

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…

Any updates?  I’m intrigued by this strain…

[passlaku]

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!

;D

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.
