Applications pratiques du zonage vitivinicole

In this work we try to know the influence of two irrigation systems (Drip and Micro – jet ) with the same levels of water applied in an experimental vineyard in the region of Felgueiras.

Today, there is need to design, produce and label terroir wines, with unique organoleptic properties and more “attractive to consumers”. For this purpose, two Saccharomyces cerevisiae yeast strains (Sa and Sb) isolated during spontaneous fermentations were used for white wine production from the Assyrtiko grape of Santorini. A third commercial strain was used as control.

This study used climatic and topographic data to characterize the sub-appellations that have been recently delineated in the Niagara Peninsula viticulture area in order to assess their potential for ripening early to late season Vitis vinifera varieties. No major differences were found in the ripening-period mean temperatures, but major differences in the diurnal temperature ranges were observed.

At least since de XIXth century, wine writers oppose quite often the wines from Gevrey-Chambertin to the wines from Chambolle-Musigny claiming that the former are more “masculine” (full-bodied, powerful tannins, leathery, rustic…) and the later more “feminine” (delicate, elegant, silky, flowery…).

In this video recording of the IVES science meeting 2023, Sara Bernardo (CITAB, University of Trás-os-Montes and Alto Douro, Vila Real, Portugal) speaks about understanding vine response to Mediterranean summer stress for the development of adaptation strategies – in the kaolin case.
