Sorry, forgot to include the temps...i crash in my keg fridge, which is set to 36F. Usually crystal clear after a day...but if was a big hop load, I let it go two. That's with the standard (for me) US-05. Flocks out really well. I imagine some of the English strains might take a little longer. But even when I do a Wit, using WLP-400, I usually only go two days tops...it's gonna be cloudy anyway after all...
I guess if I was to do a "competition" brew, I might let it go a little longer, but I'm brewing for me and my friends and family....
