Determination of aromatic characteristics from Syrah and Tempranillo tropical wines elaborated in Northeast Brazil

Abstract

[English version below]

Dans la region Nord-Est du Brésil, située à la Vallée du São Francisco, localiséee entre les paralleles 8-9º HS, la production de vins tropicaux a commencé il y a une vigntaine d’années. Dans cette région, il est possible d’avoir au minimum deux récoltes par an, car la moyenne de température est de 26 ºC, avec une pluviosité moyenne de 550 mm entre les mois de janvier-avril. Comme la pluviosité n’est pas constante, l’irrigation est donc necéssaire pour la production de raisins de table et de cuve. La recherche scientifique a commencé il y a seulement sept ans, avec des travaux ménés sur les études d’amélioration de la qualité des vins a partir d’introduction de cépages récemment implantés dans ces conditions. Les principaux cépages sont, pour les vins rouges, la Syrah, le Cabernet Sauvignon et le Tempranillo, tandis que pour les blancs, le Chenin blanc, le Moscato Cannelli et le Viognier. Le but de ce travail a été déterminer les composés aromatiques des vins Syrah et Tempranillo, afin de caractériser et d’expliquer la typicité des vins tropicaux de la Vallée du fleuve São Francisco. Les vignobles évalués ont été installés en espalier, les vignes gréfées sur le porte-greffe IAC-766 (106-8 x Vitis caribeae), avec l’irrigation par goutte à goutte. Les vins ont été élaborés en juillet 2008, par la méthode traditionnelle, en cuve en acier de 200 L, la fermentation alcoholique à été réalisée à 25 ºC et la malolactique à 18 ºC. Après la stabilisation des vins au froid, les vins ont été embouteillées et analysés 6 mois après, en utilisant la cromatographie en phase gazeuse. Comme résultats, ont été trouvés des différences intéressantes entre les compositions aromatiques des vins rouges tropicaux Syrah et Tempranillo, ce qui peut expliquer les spécificités de l’expression génétiques de chaque cépage dans ces conditions chaudes du Nord-Est du Brésil, avec des différentes typicités des vins analysés.

In Northeast of Brazil, in the Lower-Middle region of São Francisco Valley, located between parallels 8-9º of the South Hemisphere, tropical wine production has started twenty years ago. In this region it’s possible to have two or three harvests per year, because of annual average air temperature is 26 ºC and normal rainfall of 550 mm, mostly rainfall between November and April. As rainfall distribution is erratic, irrigation practice is required throughout the year to produce winegrapes. The scientific research started only seven years ago and and one of the ongoing research focus is on enhance wine quality according to the use of cultivars introduced in this region. The main cultivars cropped used are Syrah, Cabernet Sauvignon and Tempranillo for red wines, and Chenin blanc, Moscato Canelli and Viognier for white wines. The objective of this work was to determine aromatic compounds of Syrah and Tempranillo red wines to characterize and to explain the typicity of the red wines from these two cultivars in the São Francisco Valley. The vineyards evaluated were arranged on spalier, with vines grafted on IAC-766 (106-8 x Vitis caribeae) and irrigated by drip. Wines were elaborated in July 2008, by using traditional method in 200 L inox tanks , with alcoholic (25 ºC) and malolactic (18 ºC) fermentations. After cold stabilization, wines were bottled and analyzed 6 months later by using gas chromatography. As results, it was found interesting differences on aromatic composition of the Syrah and Tempranillo red wines, which allows to explain about specific genetic expression of each cultivar in the warm conditions of Northeast Brazil, with different wine typicities.

Terroir effects on wine aromatic metabolomics in the eastern foot of Helan Mountain, Ningxia, China

Aim: The eastern foot of Helan Mountain, Ningxia, China is one of the most important wine production regions in China and grape cultivation has spread in several sub-regions with different soils and cultivars. Large diversity in wine aromas have been observed at Ningxia region but which terroir factors drive those diversity in aromas remain to uncover. This study aims to investigate the impacts of grape varieties and soil chemical properties on wine aromas at Ningxia, in order to characterize the aromatic typicality of Ningxia wines and provide foundation for developing a ‘Protected Designation of Origin’ system. 

Interpreting wine aroma: from aroma volatiles to the aromatic perception

Wine contains so many odorants that all its olfaction-related perceptions are, inevitably, the result of the interaction between many odorants.

Measurement of grape vine growth for model evaluation

Within a research project for simulating the nitrogen turnover in vineyard soils and the nitrogen uptake by the grape vine, a previously developed plant growth model (Nendel and Kersebaum 2004) had to be evaluated. A dataset was obtained from a monitoring experiment at three vineyard sites with different soil types, conducted in the years 2003 and 2004.

La place du terroir dans le processus de patrimonialisation : l’exemple des paysages culturels viticoles du patrimoine mondial de l’Unesco

Eleven wine-growing sites are now on the UNESCO World Heritage List as Cultural Landscapes. If the viticultural character of these sites constitutes the main argument for the demonstration of their heritage value, the terroir and its biophysical and environmental characteristics tend however to appear in a minor mode compared to the aesthetic and cultural dimensions. In other words, the “specific characteristics of the soil, topography, climate, landscape and biodiversity” (OIV definition) are most often used as descriptive elements in the presentation of the sites, but it is more the aesthetic, historical,
