WLP San Diego Super Yeast (user update)
« on: September 02, 2011, 08:07:33 PM »
The description of this yeast is right on.  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.  I am hoping to get about 5 generations out of this tube.  Next up is a hopBurst pale ale, with ~5 oz of hops.

Cool! I have this cooking in a hoppy american brown ale and it smells great!  I am only three days into it so i hope it drops as clear as you say.

All I can say is the San Diego Super Yeast (WLP090) is a machine. With a starter it took my Double American Red Ale from 1.092 down to 1.020 in 6 days.

I can say that after tasting the sample it was a really clean fermentation around 67-68 degrees (the wort).

I detected no off flavors and the hops were really present in this one

still a little cloudy but I can take care of that in secondary

Noticed that White Labs is going to make it a mainstay yeast.  They had discussed making it a limited run unless the response was really positive, looks like it has been popular so far.

Just used it in a Harvest IPA.  Fermenting like crazy with a 1.070 OG.  Haven't pulled a sample yet.

glad to hear its going to become a mainstay - it might become a mainstay with me then as well!

I pulled a sample of IPA last night and it tastes great so far - dropped 1.070 to 1.016 in <10 days (maybe sooner - this is my first sampling).

Just pulled a sample after 6 days of primary to see how fermentation is coming along.  I still have krausen and yeast is quite obviously in suspension, so this wasn't an "is it done yet?" sample, mostly just a progress check.

Gravity is still at 1.027 after an O.G. of 1.070.  Fermentation has been conducted at a steady 66F, although I brought it up to 68F after three days of fermentation (under the assumption that I was further along than I truly was).

Sample tastes great, but I'm surprised at how slowly it is fermenting, give the description offered by White Labs.

10/7/2011 Update: Took another gravity reading 11 days after pitching, and I'm still at 1.020 with continued visible signs of fermentation.  The sample tastes fine, but I'm surprised by how slowly fermentation is progressing.  I made a 1L starter and had pitched the starter at high krausen at ~16 hours.  Not sure what may have happened, but right now I don't see a compelling reason to use this yeast again.

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.

Well, it sounds like I need to try this stuff in one of my recipes now.  Thanks for all the great info, guys.

I am noting similar problems with WLP090 as well.  Made an AIPA, mashed at 150F, pH 5.3 (yes, I calibrated them before the brew).  5% of the grist was C-20L.  Made a 2L starter ahead of time, chilled, decanted and then added 1.5L of IPA wort to the flask.  Got the yeast active and then pitched at 64F, slowly ramping up to 68F.  After 1 week I check my gravity prior to dry hopping and the beer went from 1.068 to 1.030, grrrrrrr....I made up an oxygenated starter of WLP007 and got it down to 1.020 today after 2 weeks, even after warming it up to 72-74F.  Still not where I want it.

Similar problem with a Hawaiian porter I brewed on Saturday.  This is the 5th time I have brewed this recipe and the second time I have used WLP090 in as many weeks. Worked up the starter the same way as the IPA.  Mashed at 154F, pH 5.3.  8% of the grist C-60L.  Pitched at 64F, but ramped up the heat a little faster to 72F over 3+ days.  Checked my gravity this AM, once again 1.068 to 1.020.  Usually this recipe finishes out at 1.012-1.014.

Same yeast, 2 different beers.  Despite all of the rave reviews of this yeast, it seems to be a little finicky to me.  I get consistent, reproducable results with WLP001, WLP007.  After 2 bad experiences with WLP090, I see no reason to use this yeast again.  Going to try to unstick my ferments with WLP099.  Wish me luck...

Chris White mentioned using it in an Alt competition or event; I am wondering about a Kolsch?  I like WLP 029, but if 090 can handle a cool fermentation and can drop clear quicker, then hey, I am all for giving it a go.  What do you guys think?

I can see it working well in an alt, but not a kolsch - I think it would be too clean for kolsch - none of the winey/fruity yeast aromatics would be there I would think.

Ester profile is too fuity for a kolsh. (not that it is very fruity, but kolsh needs to be very clean)  I have used in an Americn Brown and Robust Porter  with great results.   

In using for succesive generations, be sure to get enough O2 to the yeast.  I found by generation 3, the quick fermentation characteristics began to lag in the testing i dd when just shaking the carboy.  With an aeration stone and air pump, 2 15 mnute shots (one before pitching, then one 4 hours after pitching) kept the quick fermentation times.

Well I guess we have a difference of opinion here.... ;D

guess its up to interpretation:

Quote
6C. Kölsch

Aroma: Very low to no Pils malt aroma. A pleasant, subtle fruit aroma from fermentation (apple, cherry or pear) is acceptable, but not always present. A low noble hop aroma is optional but not out of place (it is present only in a small minority of authentic versions). Some yeasts may give a slight winy or sulfury character (this characteristic is also optional, but not a fault).

i don't get fruity at all from the 090 but then again, I've used it in IPA which is hard to discern.

Indeed we do!  In the competitions I have entered, the clean Kolsh get the higher ranking.  In fact, I have entered award winning  Kolsh in Lager categories and gotten high 30's consistently....just to give you an idea of how clean I am thinking!!  I would also think of the quality of esters 090 will give you.  Kolsh yeast at a higher temps expresses esters, but they are different than what you get from 090.  (that is not necessarily a bad thing...just different)


One of the things i did a couple years ago was get 4 1gallon glass jugs so I could compare yeasts side by side.  I would suggest you save some apple juice jugs or get some from your homebrew shop and try pithcing the yeasts side by side and possibly at a few different temps and see what difference it makes.

Have fun!
