Complementarity of measurements of electric resistivity of soils and ΔC13 of must in studies and valorization of wine terroirs

Abstract

The correlations between vine water deficit cumulated over the ripening period of grapes, assessed by ΔC13 in must sugar, and the main analytic variables of grapes are significant. As a result ΔC13 is a useful tool in zoning homogeneous areas according to their technological qualities when harvesting. There is no significant correlation between ΔC13 in must sugar and soil electric resistivity in the same zone. Thus it is impossible to combine a few measurements of ΔC13 and a zoning of electric resistivity to distinguish areas of which the aptitudes are different. In the event of little water deficit (ΔC13<-25,5‰), a pedological study based on zoning by means of electric resistivity is a complementary tool of zoning according to water uptake conditions, since harvest quality varies a lot with the texture of the sub-soil and its geophysic behaviour.

Relations entre critères sensoriels et analytiques des vins et des vendanges de Cabernet franc issus de terroirs et de millésimes différents en Val de Loire. Essai de caractérisation de la typicité

En France, la notion de Terroir a largement contribué à la réputation de nombreux vignobles. Elle a permis aussi d’accentuer la sensibilité des consommateurs, à la notion d’origine d’un produit. L’avenir de nombreux vignobles français semble lié à la capacité à innover en produisant des vins de qualité possédant en plus une typicité, aspect sensoriel susceptible de s’affirmer comme un facteur de vente auprès des futurs clients éduqués sur le plan du goût.

Aspetti legislativi di settore: e politiche comunitarie

Sulla base del tema assegnatomi è stata forte la tentazione di addentrarmi nel labirinto della regolamentazione comunitaria. Per buona pace degli intervenuti ho ritenuto, pero, poco utile una elencazione di numeri e riferimenti normativi che saranno brevemente riassunti in una tabella (TAB 1),

Chemical and sensory evolution of total and partial dealcoholized wine in a can

In recent years, wine consumption has been evolving towards new trends. On the one hand, awareness of health and responsible consumption has been growing, and with it, the demand for wines with lower or without alcohol content [1].

La valorisation des Terroirs Viticoles par les Indications géographiques et les appellations d’origine

Le sujet proposé dans le thème “l’environnement juridique” est plus économique que juridique, et constitue une sorte de complément au sujet qui l’a précédé : analyse des marchés, stratégies commerciales et terroirs”.

Comparison of aroma-related compounds of carbonic maceration and traditional young red winemaking in case of Merlot by means of targeted metabolomic approach

Winemaking decisions and techniques are known to affect the final aromatic composition of red wines. Winemakers put a constant effort into the improved controlling of vinification procedures to achieve better quality. Anyway an increased customer’s demand for uniqueness is often forcing them to adjust and offer new and new interesting products. To support the producers, an improved knowledge on aromatic potential as affected by classical and alternative strategies is needed.
