I was really looking forward to using this yeast and the first beer I brewed (a pale Kellerbier) was excellent. But the Festbier I brewed with repitched yeast has a weird not quite sulphury but I don't know how to describe it flavor. I brewed it in August and it has been lagering away in my beer fridge ever since then. The off flavor has lessened but is still there.
I did a group buy of 4 or 5 packs for my homebrew club as several of us wanted to try this yeast, especially after hearing Randy Mosher talk about it and because Schilling uses it for their Landbiers. But my friend (who is a big Schilling fanboy) also had the same flavor with the Vienna lager he brewed. So I've kinda given up on using it.
I did have good luck recently with the Bootleg Beta release of their
Franconian Keller Lager yeast. I brewed a Schwarzbier that is still tasting great. Next up is an amber Kellerbier. That will be the real test.
