I was planning to cold crash for a few days to help clarify my raspberry pale ale that I forgot to add whirlfloc and then dumped in 3 pounds of berry puree in after fermentation completed. At the moment it is a raspberry-opaque-ale.
My impression is that it only takes about 48 hours in the fridge to get good results, but we shall see.
I don't do secondary fermentation in a seperate vessel, since I find the beer is actually much better if it sits on the yeast cake for about 2-3 weeks. Is it best to wait that amount of time and then stick it in the fridge, or do so as soon as the fermentation is complete?
