Off topic back at ya - Agree that fish you catch is better but frozen is almost always better than "fresh never frozen" fish that has travelled for days. I think that is what Denny is talking about. If I'm at the beach I better not be eating frozen fish!

Exactly. Plus commercial fish is generally flash-frozen, which generally bypasses the problems of ice crystals tearing cell membranes that happens during a slower freeze.

So, are we in agreement for the average brewer that fresh yeast is probably better than frozen yeast?

I think that liquid yeast which has never been frozen is likely to be as good, or better, than the same yeast that has been frozen (partially or completely).

I made a starter with the previous frozen yeast. No activity. It's toast. Thanks for the replies!

Any cells that didn't survive the freezing would, upon thawing, spill their guts into the wort because their membranes were longer intact. This is called lysis, which you might recognize because it is part of the word autolysis. It might not be enough to worry about given that it's from a single White Labs tube. Did you happen to taste the starter, even though it was a dud?
