Resumen
Stabilization of wine by refrigeration assures an increase in cleanliness and effective physicochemical stabilization. The objective of the present work was to study the changes in free amino acid concentrations in rosé and white wines stabilized by precipitation in the cold, filtered through non-sterilizing filters and aged for a year in bottle. The wines derived from musts clarified by static sedimentation were compared with control wines obtained from unclarified musts. The results show that the unclarified-must wines had a greater consumption of amino acids due, probably, to the greater microbial population. Copyright © 1996 Elsevier Science Ltd.
