FIGHTING CLIMATE CHANGE WITH APPASSIMENTO ON THE VINE?10/04/2017
“We have to begin work today if we are to be ready for future necessities arising from climate change.” This is the summary from the Co-ordinator of the Masi Technical Group, Raffaele Boscaini, when talking about the ground breaking research presented today, Monday 10th April, at Vinitaly during the XXIX Masi Technical Seminar entitled: “Masi Expertise AppaXXImento: drying loft or vineyard”.
Conducted in collaboration with Milan University, the Masi Technical Group’s (#GruppoTecnicoMasi) latest project examines an innovative approach to Appassimento carried out on the vine by crushing the stalks connecting bunches of grapes to the vine, with a view to using this technique as a possible answer to climate change. The aim was to analyse the process and compare the results to traditional appassimento carried out by laying grape bunches out to dry on bamboo racks in drying lofts.
Not yet used in Valpolicella, this technique involves starting the appassimento process by crushing the stalk that attaches grape bunches to the vine and leaving the grapes on the vine during the ripening process. “Temperature increases – explains Lucio Brancadoro, a researcher in the Agrarian Faculty of Milan University – mean ever more frequent delays in the phenolic maturation of grapes, which can, however, be readily achieved if the grapes are left on the vine. Crushing the bunch stalks at harvest time interrupts the connection between the grapes and the vine, but allows the chemical and enzyme reactions to continue. This solution could prove to be particularly interesting for the production of wines like Valpolicella, whose typical softness is achieved through full phenolic maturation.”
