When should I add bentonite to my wine?

After fermentation is complete, bentonite can be used to stabilize a wine by aiding in protein, phenolic and yeast sediment suppression. To use bentonite, begin by stirring a 25-50g powdered bentonite slurry into a few liters of room temperature water. Allow the slurry to stand for at least an hour before adding the slurry to your wine.
