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.

Just weird first experience with this strain. Thought I'd share for anyone else not familiar with "jumping" yeast.
