Abstract
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.
