Observation and modeling of climate at fine scales in wine-producing areas

Abstract

Global change in climate affect regional climates and hold implications for viticulture worldwide. Despite numerous studies on the impact of projected global warming on different regions, global atmospheric models are not adapted to local scales and impacts at fine scales are still approximate. Although real progress in downscaling, using meso-scale atmospheric models taking surface characteristics into account, was realized over the past years, no operative model is in use yet to simulate climate at local scales (hundreds of meters). The TERVICLIM and TERACLIM programs aim at observing climate at local scales in different wine producing regions worldwide; simulating both climate and climate change in order to produce a fine scale assessment of the climate change impacts, thereafter simulating scenario of adaptation for viticulture, providing guidance to decision-makers in the viticultural sector.

Les sols du cru de Bonnezeaux, Thouarcé, Anjou, France

Le cru de Bonnezeaux est une des appellations prestigieuses des vins liquoreux et moelleux des Coteaux du Layon et sa réputation est ancienne. L’INAO a effectué sa délimitation en 1953. Le vignoble est situé au nord de la ville de Thouarcé et au sud du village de Bonnezeaux, le long du versant rive droite du Layon, exposé au sud-ouest. La superficie du vignoble est de 156 ha.

Impact of chitosan treatment on the physico-chemical features of a sangiovese red wine

Chitosan is gaining interest in red winemaking thanks to its ability to inhibit the development of Brettanomyces spp. yeast, or other undesired wine microbial threats. However, little is known about potential side-effects of its addition on the physico-chemical parameters of red wines.

Polysaccharide families of lyophilized extracts obtained from unfermented varietal grape pomaces

The recovery of bioactive compounds from grape and wine by-products is currently an important objective for revaluation and sustainability. Grape pomace is one of the main by-products and is a rich source of some bioactive compounds. The aim of this study was to evaluate the polysaccharide (PS) composition of extracts obtained from pomaces of different white and red grape varieties of Castilla y León. Grape pomaces were obtained after the pressing in the winemaking process.
