The Dualex readings provided by Fruition Sciences provide another level of Nitrogen update and utilization within the grapevine. Previously we, as an industry, relied on yearly or bi-yearly petiole reading for Nitrogen levels in our vines. Weekly readings provide deeper insight into the nature of the vine, especially during key physiological stages like flowering and veraison. Correlating this with development of anthocyanin in the berries and with the extraction and stabilization of anthocyanin during fermentation will continue to inform decision making...and most importantly allow us to grow better grapes and make better wine.
