Study of the Wine Clarification Process with Bentonite

The fermentation of Isabella and Pocklington grape varieties was carried out to obtain dry wine materials. The process of treating wine materials with conventional bentonite and modified bentonite at the clarification stage was studied. It was found that the acidity of the wine materials systematically decreases by the end of the treatment when using modified bentonite. It is proposed to use modified bentonite samples in winemaking technology, as they not only contribute to clarification but also reduce the acidity of the wine.
