Abstract
Thinning to one and two flower clusters per fruitful shoot significantly increased total soluble solids and total phenols but had no effect on titratable acidity of de Chaunac grapes in two vineyards differing widely in vine vigor and soil type. Treatment with 50 ppm gibberellic acid 10 days after bloom did not affect juice quality at either location. Grapes from the high vigor, heavy soil site were particularly high in titratable acidity, and potassium content was higher in berries from thinned vines in the same vineyard. An early assessment of wine quality showed the one-cluster treatment to be superior.
