A. Guitart et al., Effect of different clarification treatments on the amino acid content of Chardonnay musts and wines, AM J ENOL V, 49(4), 1998, pp. 389-396
This paper deals with the effect of five different clarification treatments
applied to must (centrifugation, cold, enzymes, bentonite, and silica gel)
on the amino acid content of macerated and non-macerated musts of the Char
donnay variety and the wines obtained from them. In general, treatment with
silica gel removed the largest number of amino acids from the must, althou
gh this effect was more noticeable in the case of macerated musts. On the o
ther hand, wines obtained from musts clarified with enzymes had the highest
concentrations in most of the amino acids studied, independently of whethe
r the musts were macerated or not.
