Technological variability of wines produced with white and red fruited hybrids cultivated in the Dolomites (Italy)

Abstract

In recent years, consumers shifted their interest towards products coming from a viticulture less dependent on chemical inputs also focusing on hybrid varieties. Although information is available in the literature about the attitude of hybrid cultivars in terms of resistance and grape composition, wines made from those varieties are not often been extensively characterized. In relation to the recent entry of several hybrids in the Italian Catalogue of Wine Grapes, we investigated the variability of the chemical composition of wine due to winemaking options. In particular, focus was on a dozen of white- and red-fruited hybrids (Solaris, Helios, Muscaris, Souvignier gris, Bronner, Aromera, Cabernet Cantor, Cabernet Carbon, Cabernet Cortis, Monarch, Prior…) mainly selected in Freiburg (Germany) and cultivated at the foot of the Dolomites, in Trentino (Italy). Wine polyphenol composition was measured, in particular focusing on the tannin fractions, anthocyanins mono and diglucoside and, for the first time, shikimic acid in comparison with vinifera grapes and wines. The extraction curves and the effects of different skin-contact options during fermentation have been investigated.

Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec

Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.

Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)

Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.

Phenological behavior and evolution of maturation of grapes of juice preparation

The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.
