Field Study

Vitazyme on Grapes – 2009, San Miguel, California

The sixth year of this California wine grape study, using the same treated rows as in previous years, revealed a recovery of the plants to some degree after severe frost damage in 2008. This year the Vitazyme treatment produced 11% more yield than the untreated control, compared to the 29% average increase for the first four years of the study. Even with an 11% yield increase, the results of this program are highly profitable, especially considering that the wine preoduced with Vitazyme treated grapes has been shown to be equivalent, if not superior to, wine produced from untreated grapes alongside. Of special note is a higher alcohol content of the Vitazyme treated wine, by 0.9 percentage point; both wine lots for 2009 are very similar.
