In economics, the perception of wine quality is not limited to sensorial characteristics: an indication of the region of production significantly affects the perception of quality and consumers’ WTP ([1]; [2]). However, [3] or more recently [4] show that even if a wine has an organic label, the taste of wine remains the predominant criterion in consumer preferences. The contribution of our experiment is to evaluate the impact of responsible attributes (organic label, Non Added Sulfites, HVE certification) on the appreciation of several red wines on the market. More than 280 consumers participated to the present study and they perform 25 tastings divided into 5 different sessions. 20 different red wines from Bordeaux Area are tasted.

Wooden barrels have been the preferred method for oak maturation for wines, but the use of alternative oak products, such as staves and oak chips have increased in South Africa due to lower production costs. This study investigated the effect of different oak products used during fermentation and ageing on the sensory profile, degree of liking and perceived quality of a South African Chenin blanc wine. The different wine treatments included an unoaked tank control wine, wines matured in 5th fill barrels, wines matured in new barrels from three different cooperages, and wines matured in 5th fill barrels with stave inserts from two different cooperages.

Wine quality traits are usually given by parameters such as aroma profile, total acidity, alcohol content, colour and phenolic content, among others

The jurist feels like an intruder when talking about terroirs. He looks at the press and tries to understand. We can read there about the cooking festival of May 30, 1996 which “..highlights products whose quality depends on a region”, that Camembert du pays d’Auge is the only one to be protected, I was thinking of camembert from Normandy, that 80% of Greek feta is made in the Netherlands, I thought it was in Denmark, and that the European Community protects geographical indications of IGP origin, probably a new category replacing the indications protected areas (1). I also learned that distributors are asking for more local products because “they come to confuse the cards in the part engaged with the big brands”. Carrefour has its “Terroirs and drawers”, Prisunic its “Vent d’Ouest”, Intermarché “Les bouquets du terroir”, Monoprix “Les terroirs de France” (2), Promodés and its brand “Reflets de France” for the “Continent” hypermarkets (3). At the same time it is asserted that “The term is a mere common noun. Unprotectable and therefore unprotected” (4).

Climate changes have important consequences in viticulture, heat waves accompanied by periods of drought are encountered more and more frequently. This study aims to evaluate the single and combined effect of water deficit and high temperatures on the thiol precursors biosynthesis in Sauvignon blanc grapes. For this purpose, a protocol has been developed for the cultivation of berries on a solid substrate. The berries, collected at three different times starting from veraison and grown in vitro, were subjected to 4 different treatments: control (C), water stress (WS), heat stress (HS), combined water and heat stress (WSHS). Water stress was simulated by adding abscisic acid to the culture medium, while different temperatures, respectively 25°C and 35°C, were managed with two illuminated climatic chambers.
