" ... there were distinct differences"
By: Rick Kocher
Date: Aug. 26, 2011
Beer brewed: Smoked Cherry Porter
Comments: I made this smoked cherry porter and I used this in one 5 gallon carboy and the WLP013 London ale in the other carboy. They both turned out great, but there were distinct differences. The 002 left a fruiter, more cherry tasting porter. I put a 3lb can of cherry puree in each carboy. However, the 013 left almost no cherry flavors, but the smokey flavors in the 013 were very evident. There was very little if any smoke character in the 002. Very interesting experiment. (Note: This review also appears under WLP002).

Will try in an ESB or Old Ale

Cascadian Dark Ale
Used this yeast on a CDA. Unfortunately for the style, in my hands it seems to have a muted hop aroma. It has a moderate (more than subtle, IMO) oaky and maybe even smoky character that would be very interesting in another style but not quite what I was aiming for in this beer. I'm looking forward to trying it again with an ESB or Old Ale.

"People absolutely loved my stout ... "

Beer Brewed:
Stout, IPA
I used this yeast to do a stout and IPA. I washed and reused the same yeast for both beers, both were a 1.062 beers. The yeast was 2 months old and I made a liter of starter for the first generation. This yeast has no real fruity ester at all. It's pretty clean. The ester that comes through is somewhat oaky and REALLY went well on the stout. People absolutely loved my stout and it was consumed very quickly. I also did an IPA with this yeast. I am incredibly pleased. No fruity esters to get in the way of the hops. This is a really clean yeast that lends itself to stouts and IPAs. It did come across somewhat dry/malty in flavor, but the perception of the maltiness is more somehow than a California ale yeast. No fusel alcohols at all and minimal diacetyl. Fermented at 65-67 degrees. I mashed at 152 and got a 78% attenuation on my IPA. I mashed at 154 to 155 on my stout and got 70% attenuation. People called my stout a dry stout. This is a great general purpose yeast. It will give you a relatively clean beer with mild oaky esters.

" ... excellent general purpose British yeast"
: Dave Brown-Smith

Beer Brewed:
Blonde Ale, London Ale, Pale Ale
Has proven excellent general purpose British yeast for pale and light flavoured British ales. Worked fantastic on Pilsner malt and Saaz blonde ale. The malt flavour from my decotion mash was nice, whilst keeping the beer light, refreshing and enjoyable. Worked great in strong (1.070 OG) London Ale and similarly styled English Pale Ale (1.045 OG). Fast fermentation (18-22c) using refrigerated WLP013 yeast slurry from previous batch.

FAQ for this yeast

I have a 1.037 English ale in secondary which was fermented with WLP013 (@ 20C). It's still astonishingly hazy with yeast after nearly 3 weeks (2 weeks secondary @ ~10-13C ambient). Is this normally a slow flocculator?

For the WLP013 fermentation, it is not usually slow, but not much will flocculate out until it is near 4C. So you can hold it at 10 longer or drop the temperature. It is also possible that it is not a yeast haze, but a permanent protein haze. It is very hard to tell the difference, the only way to know for sure is to look under the microscope.
