Pérez-Alvarez, Rosario Salinas, Ana Gonzalo-Diago, Amaya Zalacain, Teresa Garde-Cerdan. “Effect of vine-shoot and oak extract foliar grapevine applications on oenological parameters, phenolic acids and glutathione content of white musts and wines,” Oeno One (2020). I stumbled across a fascinating paper in Oeno One from a research group in Spain. In this research, grapevine shoots were sprayed with vine-shoot and oak-wood extracts. The foliar sprays had the result of reducing the final Brix/Baumé of the grapes at harvest. The authors also noted a general increase in the wine color quality for the treated vines. I think I would like to see the results from more trials, in more, different vineyards. However, this paper does seem to indicate that there is another way to dispose of vineyard canes after pruning than burning or chipping and composing them. I’ll post the abstract here with a link to the original paper. I intend to follow procedure wit...
