Ooo Oo That Smell

Pungent smell from Willy the Common's Primary. Unsure of its origins nor its composition. Could be nothing but could be something.

Using this yeast to pitch another batch this weekend is on advisory. Will inspect the beer closer during transfer from Primary to Secondary. That will be Friday or Saturday.

Update - the smell is attributed to the yeast. Prior to this I had limited experience with lager yeast which tends to produce sulfur. Ale yeast does not produce nearly as much sulfur but instead smells fruity. This beer turns out pretty good.
