A general phenological model for characterising grape vine flowering and véraison

Sustainable viticulture and winemaking continue to represent huge challenges, where a better knowledge about the functional role of biodiversity in the vineyard and wine ecosystems is required, as well as the varieties plasticity. Particular attention should be devoted to the spatial and temporal interactions between authorized or recommended varieties for a specific demarcated region and clime and vineyard conditions (such as soil type, orientation of the lines, age of the vine, density of planting, harvesting practices, among others).

The yeast Metschnikowia pulcherrima is a microorganism of great biotechnological interest, both for improving winemaking processes and for other applications outside the wine supply chain.

This report examines product quality assurance issues arising when technological aids and food additives are utilized in winemaking.

Pulsed electric fields (pef) technology holds significant promise for the agrifood industry, considering the capacity of inducing cell electroporation, due to the disruption of cellular membranes. Pef-induced permeabilization is dependent of the chosen treatment protocol (i.e. Pulse shape, electrical field strength, specific energy) and of the matrix’s characteristics (i.e. Cell radii and size, ph, electrical conductivity).

La région de production de la Gambellara et Recioto di Gambellara DOC (variété Garganega), tout en n’intéressant qu’une surface limitée, présente une certaine variabilité de milieu due à la morphologie du territoire (colline et plaine), à l’état actuel des sols et aux variations climatiques entre les différents sites.
