Climate variability and its effects in the Penedès vineyard region (NE Spain)

Abstract

This study present a detailed analysis of the rainfall and temperature changes in the Penedès region in the period 1995/ 96 – 2008/09, in comparison with the trends observed during the last 50 years, and its implications on phenology and yield. Temperature increases are higher than in previous time periods, which together with the irregular rainfall distribution throughout the year give rise to significant water deficits for vine development. Water deficits are being exacerbated during the last years by the increase of temperatures which imply an increase of evapotranspiration. The dates at which each phenological stage starts and the length of the different phenological stages are affected by temperature (accumulated degree-days and daily air temperature difference), precipitation and water accumulated into the soil. Winegrape yield was also influenced by soil water availability.

INFLUENCE OF THE NITROGEN / LIPIDS RATIO OF MUSTS ON THE REVELATION OF AROMATIC COMPOUNDS IN SAUVIGNON BLANC WINE

Production of volatile compounds by yeast is known to be modulated by must nitrogen. Nevertheless, various parameter of must quality have an impact on yeast fermentation. In this study we propose to evaluate the impact of nitrogen / lipids balance on a Sauvignon Blanc grape juice (Val de Loire).
Must was prepared from the same grapes at pilot scale. Three modalities were carried out: direct pressing, direct pressing with a pre-fermentation cold stabulation and pellicular maceration before pressing.
