Berry Shrivel
Berry Shrivel is a cluster disorder that appears just before harvest. Berries on affected clusters are flabby, the juice is watery and sour with no apparent sugar, and there is often an off-flavor.
To learn more about Berry Shrivel, see the September 2004 issue of Vineyard Views posted on this site (use the NEWSLETTERS button to the left).
