«Observatoire Mourvèdre»: (2) climatic mapping for successful plantation of Cv. Mourvèdre


A statistical model of sugar potential for Mourvèdre grapevine cultivar has been obtained using a group of 32 plots all around de south-east french mediterranean area. It is aimed to better understand the relations between viticultural practices and quality. The model shows strong influence of the temperature components on maturity. That is why a mapping valorization has been worked on at the local scale of a small viticultural region (2000 ha) and for the year 2005. The interpolation of temperature data was possible thanks to the MITEF method, which is acurate at a resolution of 50m. Rebuilding phenological stages has been done with a model using temperature summing adapted to Mourvèdre cv.. With moderate level of yield and canopy, the sugar potential for 2005 ranged from 11 to 14 %vol. depending on the location. With a maturity level of 12% vol. given as a minimal, it is thus possible to determine favourable and less favourable areas for the variety. Finally, turning up or down the level of yield or canopy gives us simulations of the impact of the grower practices on maturity potential, leading to an extent or a reduction of the possible planting area.

Impact of soil-applied and foliar-applied nitrogen on grape and wine composition

Foliar application of urea may be an efficient way to alter grape and wine composition without increasing vine vigor. However, we know little about the impact of this practice on phenolic compounds and yeast assimilable nitrogen (YAN). Adequate YAN is required for an efficient and complete fermentation, while phenolics are particularly important for the sensory profile of red wines. The goal of this study is to test the impact of foliar urea application at veraison, compared to the traditional soil-applied nitrogen fertilization early in the season, on Syrah berry and wine composition in field conditions.

The wine: a never-ending source of H2S and methanethiol

Volatile sulfur compounds (VSCs), mainly hydrogen sulfide and methanethiol (H2S and MeSH), are the responsible for reductive off-odor in wine.

Shoot positioning: effect on physiological, vegetative and reproductive parameters

[English version below]

On a étudié durant deux saisons de croissance (2002/2003 et 2003/2004) l’effet de l’orientation vertical des rameaux sur les paramètres physiologiques, végétatifs et reproductifs dans la région de Stellenbosch dans un vignoble du cépage Merlot sur 99 R conduite à espalier et taillé a cordon coursonné. Les vignes étaient espacées 2.7 x 1.5 m. L’irrigation a été appliquée quand la baie avait la dimension d’un pois et a la véraison.

Evaluation of Furmint clones in the Tokaj Wine Region

The ’Furmint’ is the most important grape variety in the Tokaj Wine Region, constituting around 65% of its vineyard area. Before the phylloxera disease many types were grown, but as selection started in the 20th century, its diversity dramatically narrowed. As a result, the cultivation of Furmint was based mainly on two heavy-cropping clones, T.85 and T.92 at the end of the ’80s. Aims of present clone research take into account that after solely quantity as target, quality emerged in the 1990’s and most recently, typicity appeared as more private estates began their own selection program.

Geostatistical analysis of the vineyards in the canton of Geneva in relation to soil and climate

Soil and climate maps at the 1:10000 scales exist for more than 12’000 ha of Swiss vineyards. The use of these maps as consulting tools for growers remains difficult due to the complexity
