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.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
