Cartography of « Terroir Units » is a Tool to Improve the Ré Island Vineyard Management (France)

Abstract

A study of « terroirs » was achieved from 2003 to 2005 in the whole vineyard of the Ré island (17, France). Over more than 1,990 ha, a cartography at the 1/10.000 scale, including characterization of climatic, pedological, geological and hydrogeological components of « Basic Terroir Units » (B.T.U.) was made. Also, a survey among wine growers was conducted. All data were treated together in a G.I.S. connected to a data base. 22 kinds of map were built (B.T.U. and components, soil water reserve, vine functioning potentials, varieties, rootstocks, viticultural practices and soil management). In a first part of this paper, results concerning climate, soil characteristics, soil water reserve, potentials for an early growth cycle, growth and yield, and also vine behaviour are presented for the main groups of « terroirs ». Other results show the effect of the water table depth on berry composition of several grape varieties. In a second part, examples are given of using advice maps (grape varieties, rootstocks, soil management) to improve the management of the Ré island vineyard, and to assist the vine growers to best adapt their practices to each « terroirs » group. Finally, an example of management of the « terroir-related » grape origin according to types of wine that are elaborated by the cooperative winery of the Ré island, is shown.

The impact of vine nitrogen status on aroma potential expression in Vitis vinifera L. cv. Sauvignon blanc

In interaction with climate and genetic or human factors, the soil is a major component of the viticulture terroir. The mineral composition of the soil influences vine performance and wine sensory attributes. Among the elements that vines take from the soil, nitrogen is the one that has the strongest impact on vine physiology, vigor and grape composition. In addition to its major effect on primary metabolites in berries, nitrogen plays also a decisive role in the secondary metabolism, especially in the production of key compounds for berries quality, like volatile thiols, methoxypyrazines and glutathione (GSH).

Georgian vitis germplasm: conservation, research and usage

Grapevine Vitis vinifera L. is a leader perennial crops for the Republic of Georgia, the South Caucasus. This is a region where the first wine making practice was initiated 8.000 years ago (McGovern et al. 2017) and a spot of grape domestication. The country of Georgia holds 525 local and more than 60 breeding varieties – they are preserved in 9 field collections inside the country.The list of recommended wine cultivars contains 34 names, including 27 old autochthonous varieties and covering 94% of the country’s vineyards.

HEAT BERRY : Sensitivity of berries ripening to higher temperature and impact on phenolic compounds in wine

The grapevine is an important economical crop that is very sensitive to climate changes and microclimate. The observations made during the last decades at a vineyard scale all concur to show the impact of climate change on vine physiology, resulting in accelerated phenology and earlier harvest (Jones and Davis 2000). It is well-known that berry content is affected by the ambient temperature. While the first experiences were primarily conducted on the impact of temperature on anthocyanin accumulation in the grape, few studies have focused on others component of phenolic metabolism, such as tannins.
