Field Study

Vitazyme on Grapes – 2008, San Miguel, California

The fifth year of this California wine grape study was very unlike the pre- vious four years, in which the yield increase averaged 29% per year. In 2008 the highly unfavorable weath- er conditions at blossom time resulted in a poor berry set, especially with the Vitazyme treatment, that gave yields for both treatments about 50% lower than the previous year. Thus, the yield data for 2008 is not rel- evant to true treatment effects. Juice quality, however, was superior for the Vitazyme treatment in 2008, with a brix level 0.7 percentage point higher for the Vitazyme treatment. A view of the vineyard during the entire year showed superior vine and leaf growth for Vitazyme compared to the control.
The yields for the first four years of the study are as follows:
The first four years of this Cabernet Sauvignon vineyard study produced an average of 29% more grapes with Vitazyme applied four times during the growing season. With the wine from these two treatments being equivalent each year — by some opinions even favoring Vitazyme — there is every reason for the grape grower to utilize Vitazyme in his production system to greatly increase yield without decreasing wine quality.
