Just another bit of evidence that mfgr attenuation and alcohol tolerance
numbers for brewing yeast are pretty much guesses:
I have a high-gravity lager finishing up primary pitched with this
yeast. SG was 1.104, looks like the FG will be 1.015 or less, for an
apparent attenuation of around 86%, and an alcohol content of 12% or so.
The numbers given by White Labs are 80% and 10% respectively. My guess
is that the yeast could keep on going past 12%, but who knows?
No fruity or off flavors in the beer, so the yeast seems to have
performed quite well. I'm figuring on a year or so of aging.

Personally, I think they should stop printing attenuation numbers for the
strains and go with a "low, medium, high" type rating like they use for
the flocculation. The attenuation numbers don't really mean what most people
think they mean, and often cause a lot of confusion.
