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.

Bioprotection of grape must by Metschnikowia sp.: genericity and mechanism

The market trend heads to food products with less chemical inputs, including in oenology. During the winemaking process, sulfites are commonly use to avoid microbiological contamination and stabilization of the wine thanks to its antimicrobial and antioxidant activities. Nevertheless, this use is not without consequences on human health and environment, leading for example to allergic reaction and pollution. A biological alternative to these sulfites has emerges: the bioprotection.

Revisiting the effect of subsurface irrigation and partial rootzone drying on canopy size and yield of Cabernet Sauvignon using remote sensing techniques

Irrigation is an essential tool for grape production, especially where rainfall does not meet the optimal water requirements needed to achieve yield and quality targets. Increased evaporative demand of grapevines due to changing climate conditions, and a growing awareness for sustainable farming, require the improvement of irrigation techniques to maximize water use efficiency, i.e. using less water to achieve the same yields or the same water but larger yields. In this study, the performance of Cabernet Sauvignon vines was compared under three irrigation techniques: conventional aboveground drip irrigation, subsurface irrigation installed directly under the vine row, and partial rootzone drying in which two subsurface lines were buried in the middle of the two interrow spacings on each side of the vine row with irrigation alternated between the two lines based on soil moisture content.

Characterization of commercial enological tannins and its effect on human saliva diffusion

Commercial oenological tannins (TECs) are widely used in the wine industry. TECs are rich in condensed tannins, hydrolyzable tannins or a mixture of both. Wine grapes are a important source of proanthocyanidins or condensed tannins while oak wood possess a high concentration of hydrolyzable tannins (Obreque-Slier et al., 2009). TECs contribute with the antioxidant capacity of wine, catalyze oxide-reduction reactions and participate in the removal of sulfur compounds and metals.

Within-vineyard spatial variation impacts methoxypyrazine accumulation in the rachis of Cabernet-Sauvignon

To investigate the impact of spatial variation in vine vigour on the accumulation of methoxypyrazines in the rachis of Cabernet-Sauvignon. Cabernet-Sauvignon rachis has been shown to contain significantly higher concentrations

Influence of coinoculation of L. plantarum and O. oeni on the color and composition of Tempranillo wines

AIM: The aim of this research was to determine the influence of performing malolactic fermentation (MLF) of Tempranillo wines by coinoculation with Lactobacillus plantarum or Oenococcus oeni and Saccharomycescerevisiae on the composition and color of the final wines in comparison with sequential inoculation with Oenococcus oeni and spontaneous MLF. METHODS: Around 1500 Kg of Tempranillo grapes from Pagos de Anguix winery (Anguix, AOC Ribera de Duero, Spain) were harvested at the optimal maturity
