When your wine is thru fermenting, rack, add 1/4 teaspoon of pot. meta (5 gallons) and add your fining agent. Allow a few weeks for the sediment to drop. It will continue to drop even though it may look clear. 4 weeks is suggested. I allow 6 prob. the maximum.
Then rack off of the sediment.
You may wish to add pot. sorb ate at the 1st racking since you'll prob. want to advance the timeline on a skeeter pee as opposed to a wine.
