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.

Influence of harvest time and withering length combination on reinforced Nebbiolo wines: phenolic composition, colour traits, and sensory profile

Sforzato di Valtellina DOCG is a reinforced dry red wine produced in the mountain area of Valtellina alpine valley (North Italy), using ‘Nebbiolo’ grapes that undergo a withering process. This process impacts on the grape composition due to a sugar concentration and changes in secondary metabolism influencing volatile organic compounds (VOCs) and polyphenols.

Phenotypical impact of a floral somatic mutation in the cultivar Listán Prieto

The accession Criolla Chica Nº2 (CCN2) is catalogued as a floral mutation of cultivar Criolla Chica (synonym for cv. Listán Prieto). Contrary to what is observed in hermaphrodite-cultivated varieties like Criolla Chica, CCN2 exhibits a prevalence of masculinized flowers. Aiming to study the incidence and phenotypical implications of this mutation, CCN2 plants were deeply studied using Criolla Chica ‘Ballista’ (CCBA) as control plants. For each CCN2 plant, two inflorescences per shoot were sampled and segmented into proximal, mid and distal positions, relative to the pedicel. Flowers were observed through magnifying lens and classified according to OIV151 descriptor.

New varieties descendant from Monastrell with lower sugar and high phenolic content adapted to warm climates

Given that climate change is a continuous process, it is necessary to constantly search for new strategies that help the viticulturist sector to mitigate its consequences. All adaptation strategies will have a greater or lesser effect that in turn will be marked by the times of action. As a long-term action, a genetic breeding program to obtain new varieties descendant from Monastrell has been developed in the Region of Murcia (more specifically, in the IMIDA Research Center) since 1997. In this program, new red varieties have been developed through directed crosses of the Monastrell variety with other varieties such as Cabernet Sauvignon, Tempranillo and Syrah.
