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.

EFFECT OF WHOLE BUNCH VINIFICATION ON THE ABUNDANCE OF A SWEETENING COMPOUND

In classic red wine-making process, grapes are usually destemmed between harvest and the filling of the vat. However, some winemakers choose to let all or a part of the stems in contact with the juice during vatting, this is called whole bunch vinification. For instance, this practice is traditionally used in some French wine regions, notably in Burgundy, Beaujolais and the Rhone Valley. The choice to keep this part of the grape is likely to affect the sensory properties of wine, as its gustatory perception1,2.

Talking about terroir

When talking about terroir, scientists and lay wine tasters, very much including wine journalists and wine growers, too often talk past one another.

A new path for sustainable development. First results in a Venetian “bio-métaéthique company“ (Italy)

This paper will show the results of changes in income in a Veneto winery located in the municipality of Motta di Livenza (Treviso) in the North East of Italy, determined by the application of the “Holistic Universal Sustainability Charter” Metaethic 4.1CC “or” Sustainability Charter BIO-MétaÉthique 4.1CC “of GiESCO (Carbonneau, Cargnello, 2017).

Under-vine cover crops: impact on weed development, yield and grape composition

This study aims to evaluate the interest of using an under-vine cover crop as a sustainable management tool replacing herbicides or tillage to control weeds, evaluating its effects on yield and berry parameters in a semi-arid climate. 
The performance of Trifolium fragiferum as an under-vine cover crop was evaluated in 2018 and 2019 in a Merlot vineyard in

Development of bioprospecting tools for oenological applications

Wine is the result of a complex biochemical process. From a microbiological point of view, the grape berry is characterised by a heterogeneous microbiota composed of different microorganisms (yeasts, bacteria and filamentous fungi) which will play a predominant role in the quality of the final product. At this level, yeasts play a predominant role in the chemistry of wine, as they
