Effect of Bentonite Additions during and after Fermentation on Wine Composition and Sensory Quality JF American Journal of Enology and Viticulture JO Am J Enol Vitic.

Amerine YR 1969 UL http://www.ajevonline.org/content/20/2/101.abstract AB Added bentonite caused few significant changes in wine composition. Total nitrogen content was usually reduced about 10% by adding 500 mg/l of bentonite, Adding bentonite before fermentation was less effective in protein-stabilizing a wine than adding if after. Wine quality was generally improved slightly, though usually not significant by bentonite addition.
