Influence of edapho-climatic factors on grape quality in Conca de Barberà vineyards (Catalonia, Spain)

Abstract

Soil and climate of 3 vineyards have been characterised in order to determine their influence on grape quality. These vineyards are located in Conca de Barberà (Catalonia, NE Spain) and belong to Cabernet sauvignon and Grenache noir cultivars. All 3 plots are very close, so only interannual climatic data of the nearest meteorological station have been considered. Different climatic indexes have been calculated from climatic data. The studied vineyard soils present very different textural classes and rock fragment contents, causing very distinct soil water regimes. Besides determining chemical and physical properties of soils, the soil water availability has been characterised using capacitance sensors at different depths for the period from 2003 to 2005. Data of quality of grapes were available. Statistical techniques, concretely Principal Component Analysis and Multiple Regression Analysis, have been used to relate edapho-climatic factors to grape quality. The results show that edapho-climatic data have a high power of estimation on grape quality (generally, R2 higher than 0.75). Climate appeared to be the most influencing factor, followed by water availability. Soil had also influence on grape yield and some must data.

Novel insights into Passito wines aroma typicality. Rationalizing the markers of varietal and geographical origin of Amarone DOCG

Valpolicella is a famous Italian wine-producing region (Paronetto & Dellaglio, 2011), whose main characteristic is the extensive use of the post-harvest withering technique, which takes place in naturally ventilated rooms called ‘fruttai’ (Bellincontro et al., 2016).

The role of molecular ecophysiology in terroir expression

Terroir is a complex concept which associates soil, climate, grape variety and cultural practices that include the training system and oenological techniques. It is a type of social construction with man at its centre. The typicality of a wine is also a social construction which is the result of an agreement among specialists vis à vis a given quality of the wine whose references are the wine’s origins (e.g. terroir) and taste.

Preliminary studies on polyphenol assessment by Fourier transform-near infrared spectroscopy (FT-NIR) in grape berries

NIR spectroscopy has widely been tested in viticulture as powerful alternative to traditional analytical methods in the field of quality evaluation. NIR instruments have been used for assessing must and wine quality features in several works, but little information regarding their application on whole berries for polyphenol determination is available.

Potentiel des sols viticoles et qualité des vins

La qualité des vins dépend de différents facteurs et procédés, notamment de la nature des terrains viticoles. Dans ce travail, nous avons cherché à établir les liens entre descripteurs pédologiques des parcelles et descripteurs sensoriels des vins. Sur la base de Classifications Ascendantes Hiérarchiques (CAH) et d’Analyses en Composante Principale (ACP), il a été possible d’établir des liens entre la nature des parcelles (sableuse, argileuse, sablo-graveuleuse) et certains descripteurs sensoriels des vins (chaleur, astringence, fruit noir) et plus globalement avec le type de vins élaborés.

Viti-Tunnel, an automatically removable protection against diseases, frost and hail, a way to drastically reduce the use of pesticides

Viti-tunnel®, une innovation imaginée pour répondre à deux des objectifs majeurs des viticulteurs : 1.la sécurisation de la vendange : viti-tunnel® permet de protéger les vignobles des pertes de récolte dues aux maladies, au gel et à la grêle. 2.la réduction des pesticides : viti-tunnel® permet de réduire de plus de 90 %, le recours aux produits phytosanitaires et aux passages de pulvérisateurs, et ce, en toute sécurité pour la vendange. Un dispositif automatisé pour protéger les vignes viti-tunnel® est un dispositif de mise à l’abri automatique des rangs de vigne pendant les pluies et les évènements climatiques extrêmes.
