Abstract
Affected grape bunches contain both shrivelled and non-shrivelled berries. The juice harvest from the former is less than one-half that from the letter. The wine obtained from shrivelled grapes is low in alcohol and highly acid. The alcoholic fermentation occurs with difficulty and the malolactic fermentation does not occur naturally. The wine is unharmonious and unbalanced. In addition, it as a lesser amount of higher alcohols and of higher esters.
