I use one of those Aerating spinner things with my drill to aerate.
I was wondering if it's possible to aerate too much?
Wyeast has a good video here on the subject:
Primary: Cession Ale (4% pale ale with Citra and Cascade)(1/31/15)
Secondary: Grandma's Liquid Apple Pie (1/17/15)
Bottle Aging: Ice Cider with store bought frozen concentrate (9/15/14)
Drinking: Left Hand Milk Stout Clone (11/21/14), and Beer Made The Right Way
But yes you can over aerate, if using pure oxygen
Here's another vid on yeastiness (plus she's pretty cute)
