Ripening of Vitis vinifera grapes varieties in São Joaquim, a new wine growing region, Southern Brazil

Abstract

This report has investigated the ripening characteristics of Vitis vinifera grapes Cabernet Franc, Merlot, Sangiovese and Syrah in two consecutive vintages (2006 and 2007), in order to evaluate the adaptation from these recently varieties planted in São Joaquim town, Santa Catarina State, Brazil. The berries had been collected at 10-day intervals from véraison to harvest and in have been analyzed at levels of pH, total acidity (TA), total soluble solids (TSS), maturation index (TSS/TA), total monomeric anthocyanins (TMA) (malvidin-3-glucoside, mg/100g skin), total polyphenols index (TPI), and Color Intensity (CI). At maturity, values of pH, TA and TSS ranged from 3.3 to 3.5; from 0.60 to 0.80 (mg of tartaric acid/100 mL) and from 19 to 23.5 ºBrix, respectively. Maturation index ranged from 29 to 40, and significant differences (p< 0.05) have been observed among different grapes varieties, but not between vintages. The values of TMA, TPI and CI ranged from 864.6 to 352.1; from 126.1 to 45.5 and from 20.66, respectively, and significant differences have been verified among varieties and also vintages (p< 0.05).

A climatic characterisation of the sub-Appellations in the Niagara Peninsula wine region

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.

WHITE WINES OXIDATIVE STABILITY: A 2-VINTAGE STUDY OF CHARDONNAY CHAMPAGNE BASE WINES AGED ON LEES IN BARRELS

Ultra-premium champagne wines are characterized by a long stay on laths. The goal of the winemaker is to use all possible oenological techniques to keep the aromatic freshness of the future products. To that purpose, some champagne base wines can be aged on lees in oak barrels. However, if it is now acknowledged that such ageing practices contribute to the oxidative stability of dry white wines, no study has been done on Chardonnay champagne base wines designed for a long ageing on laths [1].
