Bentonites, interaction with wine proteins and fermentation aromas

The results of the first year experimentation showed that the “wine matrix” affects the effectiveness and the affinity of bentonite. For instance: in case of a product rich in macromolecules deriving from the yeasts, the deproteinising effect of the clays is less important, probably because the colloidal system reduces their effectiveness and because part of the macromolecules can have the same charge of the adjuvant.
