Just tried out my new stir plate (great deal at Bell's by the way Bells Stir Starter) with some Wyeast German Ale. I was impressed by how much more yeast I got with a 1.5 L stir plate starter than I used to with my old "occasional shake" method doing 3L non-stir plate starters. I did the starter at room temp (75 F).
Anyway, the question: I noticed a very intense, wine-like, cidery smell coming from the starter when I turned off the stir plate at 18 hours. It was a very fresh yeast pack (Sept 11, 2013 date) from my LHBS that swelled right away when smacked. It didn't smell infected or cheesy, just really intense and winey. Never had this smell with my previous non-stir plate method starters. I am wondering if this is a typical by-product of continual oxygenation?
It currently chilling in the fridge, and I will definitely decant the wort prior to pitching.
