I bought a pack Wy2042 Danish lager yeast, put it in the fridge and forgot
about it.
Six months later, I found it, half frozen.
Nevertheless, I thought I'd have a go and see if it was still viable. I
smacked the pack but didn't get any swelling after a couple of days. I made
a starter and pitched it. Fermenation took off very slowly and I left the
starter going for a couple of weeks. Worried that it might be infected, I
followed Wyeast's instructions on yeast washing using phosphoric acid and
got a new 4 Litre starter going, which took off like a rocket. I got a good
lot of sludge and used it in a pilsner style of beer.
Now, some 8 weeks later, I am trying this beer and it is somewhat under
attenuated, quite sweet. I balanced it by adding some hop extract and it is
really good beer, although it does have a strange (but not unpleasant)
smell.
Now here's the question. Is WY2042 a known under attenuator OR, when I went
through starter/washing procedure, manage to isolate and grow a wild yeast
organism instead.
I should have measured the FG before posting this, I'll do it this evening
and see what it is. BTW, the recipe was pretty basic, Pils malt, a little
crystal and about 15%vienna.

I've used 2042 quite a bit and not had any problem with
underattenuation.
