Discriminant value of soil properties for terroir zoning

Abstract

Environmental analysis (climate, vegetation, geomorfoloy-lanscape, lithology and soil) and its integration in a quality index taking the Appellation of Origin as the sole universe are used as general methodology for terroir zoning in Spain (Sotés and Gómez-Miguel, 1986-2005). This methodology is also applied to specific aspects of different Spanish Appellations of Origin (size, distribution and landscape peculiarities and vine occupation index). In this work, the whole set of results of all Appellations of Origin is taken as the universe (2.323.094 ha of surface and 144.248 ha of vineyard) and the two higher taxonomic units (soil series), where more than 75 % of the vineyard is located, are taken as comparative elements. Unit characterization is made with ninety soil variables and a multicriterion method, which explains behavior differences in these variables and in the vineyard quality index, is used for comparison. This analysis shows how every compared unit has a more similar behaviour to different units of the same Appellation than to other units with the same soil taxonomy but from different Appellations, except for more closed Appellations with similar environmental characteristics. The value of soil variables as discriminant elements for terroir classification in zoning studies can, then, be known. In the studied cases of this work, the overall statistic behavior of the variables set is related to the wine production specific characteristics of every Appellation.

Island and coastal vineyards in the context of climate change

Aim: The notion of “terroir” enables the attribution of distinctive characteristics to wines from the same region. Climate change raises issues about viticulture, especially the growth of the vines and even more importantly the economic situation of actual wine-growing regions (Schultz and Jones 2010; Quénol 2014). Several studies have addressed the impacts of climate change on viticulture in

Impact of climate on berry weight dynamics of a wide range of Vitis vinifera cultivars 

In order to study the impact of climate change on Bordeaux grape varieties and to assess the behavior of candidate grape varieties potentially better adapted to the new climatic conditions, an experimental vineyard composed of 52 grape varieties was planted in 2009 at the INRAE Bordeaux Aquitaine center[1]. Among the many parameters studied since 2012, berry weight for each variety was measured weekly from mid-veraison to maturity, with four independent replicates. The kinetics obtained allowed to study berry growth, a key parameter in grape composition and yield.

Protein stabilization of white wines by stabilizing filtration: pilot studies

Protein stabilization is an important part of the winemaking process of white wines, and in this work we present the results of protein stabilization of different monovarietal wines (Xarel.lo, Chardonnay, and Muscat) by a continuous stabilizing filtration process using a column packed with zirconium oxide operating in a continuous regime in a closed loop at pilot scale.

Towards multi-purpose valorisation of polyphenols from grape pomace: Pressurized liquid extraction coupled to purification by membrane processes

Grape by-products (including skins, seeds, stems and vine shoots) are rich in health promoting polyphenols. Their extraction from winery waste and their following purification are of special interest to produce extracts with high added value compounds. Meanwhile, the growing concern over environmental problems associated with economic constraints, require the development of environmentally sustainable extraction technologies. The extraction using semi-continuous subcritical water, as a natural solvent at high temperature and high pressure a technology is promising “green” technology that is environmentally friendly, energy efficient and improve the extraction process in plant tissues.
