LHBS didn't have the yeast I wanted but did have WLP002.
This is fine because I was making a porter/stout. Read the description and thought it would compliment fine. No problems.
BTW - man liquid yeasts are expensive.
Made my starter. No issues. Next day its floc'd out ... but I notice the yeast cake "jumping" or "bubbling". Weird. Cold-crashed the starter and the bubbling went away.
Brewed and pitched my yeast. Fermented great. But then the "jumping" or "bubbling" continued in primary for 3 weeks. Thought I was infected. I was freaked out. This was an expensive brew.
Turns out this is normal for certain yeasts.http://www.homebrewtalk.com/f163/wyeast-1968-jumping-globs-yeast-468093/
The sample I took tasted delicious. And it fermented perfectly to anticipated FG. So. Didn't think I would use this yeast again... but I might. The beer tastes great after all.
Just weird first experience with this strain. Thought I'd share for anyone else not familiar with "jumping" yeast.
