Al.... I notice you're in MN... watch your ferment temps. I've found that my SP likes it better the warmer it gets. I've heard a from a few sources that wine yeast prefer hot temperatures for fermentation. >75*F is where Montrachet (which I use) LOVES to be. I was trying to brew this over the winter and had issues with the batches until I figured this out. I'm on vacation till after Christmas so I may whip up a batch myself and throw it in the fermentation chamber on some heat.
Women are like yeast... You gotta keep them at the right temperature if you want to get anything out of them!
