Abstract
The amino acid compositions of musts from grapes cropped at several different levels were determined. The proteins of the grapes from each treatment were isolated by Sephadex gel column. The protein complex was further separated by electrofocusing equipment into seven or eight fractions. The percentage of each fraction was determined for each treatment. The percentage of the first two fractions varied slightly with crop load. Amino acid composition varied between the fractions but not between crop levels.
