7/08/05 Concord Berry Weight Update

Dr. Terry Bates

Fredonia Vineyard Laboratory

The 25 days after bloom fresh Concord berry weight curve shows that the vines are just slightly behind the 6 year berry weight average. If you are crop estimating today and are using the Crop Estimation Chart at:

I would predict that the berries are between 35-40% of the final weight. The following chart is based on vines that bloomed on 6/13. If your vineyard bloomed earlier or later than 6/13 then you should adjust your prediction accordingly.
