PVGIS: a free online solar photovoltaic calculator tool to optimise light harvesting in viticulture

R. Zorer et al.; Fondazione Edmund Mach (FEM), Italy; Dept. of Viticulture, ARC Infruitec-Nietvoorbij, Stellenbosch, South Africa

The Photovoltaic Geographical Information System (PVGIS ©European Communities, 2001–2017) had been developed from solar radiation data estimated from satellite using the Satellite Application Facility on Climate Monitoring (CM SAF) models and representing the period 1996-2011.

The article shows examples of estimations for two locations, i.e. San Michele all'Adige, North Italy, and Stellenbosch, South Africa.

Article based on the poster presented at the at the 10th edition of Enoforum (May 16th-18th, 2017, Vicenza, Italy)

A new device for stabilisation of white wines throughout a continous flow system

Parpinello, G.P., Ricci, A., Serantoni, M., Balducci, A., Ragni, L., Versari, A.; University of Bologna, Italy

Proteins occurring in wine originate from several sources during the winemaking process. Protein content in wines ranges from traces up to hundreds of mg/L, and may cause physical instability in wh...

An electrochemical method for real time measurement of polyphenols during winemaking

By Christine Pascal, Nelly Champeau, Jean Baptiste Diéval, Stéphane Vidal; Vinventions, Enology team, France

Polyphenols are known to play a major role in must oxidation as well as in wine aging and oxidation. However, they are difficult to measure in the cellar due to lack of adequate technology. Therefo...
