I actually allow mine to stay in the fermentor for about 2 weeks before racking into my kettle.... It settles naturally that way. I have some sparkaloid from the owner of this forum but I haven't used it yet. It's supposed to floc everything down to the bottom to make the process faster but speed isn't my thing.

Never seemed to make a difference for me using turbos. Put it somewhere cold over night then siphon off everything but the cloudy crap at the bottom and run it.

Distilleries don't do a second fermentation stage at all. 3-5 days and into the still. It seems to be a highly debateable topic here IMO because a lot of guys on this board make beer and wine and simply apply the same methods. When i've tried waiting and clearing with sparkaloid and even a wine filter machine it made no difference in my end product so i gave it up.
