Pedological factor influence on the viticultural zoning of the Aljarafe Alto (Seville, Spain)

Abstract

Aljarafe Alto est une petite zone naturelle dans le département de Séville (Espagne), où le cépage autochtone cultivé est le Palomino Garrido Fino. Les auteurs étudient l’influence de 3 types de sols (sol Rouge fersialitique, sol brun calcaire et Rendsine blanche) sur 9 vignobles de la variété “Palomino Garrido Fino” du “Aljarafe Alto” (Seville).
Les résultats expérimentaux montrent des différences statistiquement significatives pour quelques caractéristiques du potentiel agronomique des sols et leurs conséquences sur le niveau de nutrition minérale des vignobles et sur la qualité des récoltes.
Le traitement statistique des paramètres oenologiques des microvinifications des moûts issus des vignobles étudiés montre le facteur pédologique comme le critère les plus relevant dans le zonage vitivinicole de la région Aljarafe Alto (Seville).

The Aljarafe Alto is a small natural area in the province of Seville (Spain), where the autochthonous vine is the cultivar Palomino Garrido Fino. The authors study the influence of 3 types of soils (Mediterranean red soil (calcic Rhodoxeralf); calcareous brown soil (calcixerolic Xerochrept); white Rendsina (calcicxerollic Xerorthent) in nine vineyard plots. The results reveal statistically significant differences in some characteristics of the agronomie fertility of the soils and, as a consequence, in the mineral nutrition stage of the plants and crop qualify.
Musts proceeding from the vineyard plots chosen for this study were fermented in laboratory. The results from statistical treatment of oenological parameters of these wine samples reveal the pedological factor to be the most relevant for the viticultural zoning of the Aljarafe Alto zone.

Volatile composition of base wines to obtain sparkling wines from seven autochthonous grape varieties from Castilla y León (Spain)

The aim of this work was to characterize the aromatic profile of white and rosé base wines for the elaboration of sparkling wines from seven autochthonous grape varieties of Castilla y León. The ‘Albarín’, ‘Godello’ and ‘Verdejo’ white grape cultivars contribute with more fruity notes than the ‘Viura’ and ‘Malvasía’ cultivars; and ‘Prieto picudo’ coloured grape cultivar has more fruity character than ‘Garnacha’.

Soil preparation practices to eliminate soil restrictions to grapevine root distribution for the establishment of sustainable vineyards

Grapevine yield and wine quality are dependent on good quality vegetative growth and root development. Soils that restrict proper grapevine root development, together with the high cost of establishing a new vineyard, require effective soil preparation to sustain productive vineyards for 25 years. This study reviews soil preparation research conducted over the past 50 years and identifies best practices to remove soil physical and chemical impediments to create optimum conditions for root growth.

Assessing the Effectiveness of Electrodialysis in Controlling Brettanomyces Growth in Wine

Brettanomyces yeast can negatively impact the quality and stability of wines, posing a significant challenge to winemakers. [1] This study aims to develop novel management practices to limit Brettanomyces impact on wines by evaluating the effectiveness of electrodialysis (ED) technology in removing magnesium (Mg2+) from wine to prevent the development of Brettanomyces yeast. The ED technique utilizes charged membranes to extract ions from the wine, and it is considered an alternative to cold stabilization that requires less energy. [2]

Geological, mineralogical and geochemical influences on the cultivation of vines

Aims: The aims of this study are to determine the influences of the local geology, mineralogy and geochemistry of surroundings, substrate and soil on the cultivation of vines, these as an additional factor of specificity and locality in the production of wine and definition of terroir, as well as for the discrimination of local variance of substrate and soil properties for the strategic management of cultivation plots and/or the evaluation of new cultivation regions, necessary within a scope of global climate change.
