Last week I decided to brew a German Pils using WLP830, just as a cold snap hit our area. Everythign went well with my brew, except that my fermenter is in the garage and it's so cold my fridge can't keep the wort above 50. Right now it's at 48 degrees inside my fridge. The yeast is going, although the lag time was a little long. I'm not sure if I need to do anything to raise the temperature a little. Is 48 degrees too cold to make good beer? I thiink White Labs says the minimum temp for that yeast is 50.
