Étude intégrée et allégée des terroirs viticoles en Anjou: caractérisation et zonage de l’unité terroir de base, en relation avec une enquête parcellaire

Abstract

The terroir concept is presented as the basis of the A.O.C system, in the french vineyards. The “Anjou terroirs” programme aims at bringing the necessary scientific basisfor a rational and reasoned exploitation of the terroir. lt must lead to finalizing a lighter, more relevant integrated method of characterisation wich could be generally applied. The “Basic Terroir Unit “concept, elaborated earlier, is now more precise,from the standpoint of soil characterisation, because of the current study. This allowed to initiate the Rock, Alteration, Alterite ground model wich is currently being tested. A viticultural survey based on parcels, has been carried out among vine-growers, in order to study the possibilities of lightening the terroir characterisation method. lt includes for example, questions concerning empirical knowledge of the soil, the climate of the parcel, vine budbreak precocity, water supply and vigour potential of vine, as well as question on overmaturing aptitude of the parcel. These variable are influenced by the natural factors of the “terroir” and they can be logically explained. The main results of the study are presented and discussed in this paper.

The interaction between wine polyphenolic classes and poly-L-proline is impacted by oxygen

Oxygen plays a key role in the evolution of wine chemistry, within the non-volatile matrix. Polyphenol composition and structure, as well as the process of tannin polymerisation are directly impacted by oxidation, and this can occur during both fermentation and ageing.

Determination of selected phenolics, carotenoids and norisoprenoids in Riesling grapes after treatment against sunburn damage

Riesling represents the most widely cultivated grape variety in Germany and is therefore of particular economic interest. During recent years an increase in the petrol-note as well as in undesirable bitter and adstringent notes has been reported. These changes are most likely linked to increasing temperature and sunlight exposure of grapes due to climate changes.
The “petrol note” is caused by the formation of the C13-norisoprenoid 1,1,6-trimethyl-1,2-dihydronaphthalin (TDN), which originates from acid-labile precursors formed by the carotenoid degradation in the grape.

Influence of edapho-climatic factors on grape quality in Conca de Barberà vineyards (Catalonia, Spain)

Soil and climate of 3 vineyards have been characterised in order to determine their influence on grape quality. These vineyards are located in Conca de Barberà (Catalonia, NE Spain) and belong to Cabernet sauvignon and Grenache noir cultivars. All 3 plots are very close, so only interannual climatic data of the nearest meteorological station have been considered.
