Field Study

Vitazyme on Grapes – 2007, San Miguel, California

This was the fourth year that Vitazyme was applied to the same grape plants in this vineyard near San Miguel, California. The Cabernet Sauvignon grapes responded very well to the product, increasing in yield by 27%, the vines also significantly increasing in length and girth. They also

had more photosynthesizing leaves after harvest, until the first frost in December. The yield increase was due to larger grapes in the treated area, and possibly more bunches, but the bunch numbers were not counted. In spite of the higher yield, the juice brix and quality were equivalent for the two wine batches. These two lots of wine from the Vitazyme and control treatments will be evaluated periodically throughout the coming year for quality and taste differences.
The yields for the three 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.
