I'm cold crashing a True Blue Canadian Ale kit before bottling. I've stuck fermenters in the garage during the winter overnight and drop down to about 50F but haven't cold crashed in a fridge yet. I have a modified soda machine that my fermenter fits into. Whats a good cold crash temp and for how long? I keep this machine cold... just above freezing. I don't want to damage the yeasts left as I'm going to be bottle conditioning. I plan on Bottling on Sunday and I just put it in the machine Friday morning.
