Zonificación climática de las D.O. Rueda y Toro y vinos de la tierra de medina del campo

Abstract

La producción vitícola es el resultado de una serie de factores influyentes (variedad, patron) dentro de un medio ecológico­-climatico-edafico, en el que se interactua por medio de técnicas de cultivo adecuadas.
En la caracterización climática del viñedo estan presentes tanto los elementos tradicionales (temperatura, precipitación, insolación, etc.) así como los factores geográficos (latitud y longitud, altitud, orientación, exposición, proximidad a masas de agua, etc).
Para ver la influencia sobre el vinedo, en las distintas fases de su ciclo vegetativo, se cuantifican y se analizan los parametros mas relevantes en las D.O. Rueda y Toro, Tierra de Vinos.
Las caracteristicas climáticas más destacables de la región pueden ser resumidas (Garcia Femandez, 1986) como sigue:
– clima continental determinado por los efectos de encajamiento y aislamiento definidos por las cadenas montañosas que la rodean.
– rigurosos ( crudos) y largos inviemos: bajas temperaturas medias y generalización de los val ores negativos de las temperaturas medias de las minimas del mes de enero, minimas absolutas acusadamente bajas y largo periodo invernal.
– veranos cortos, relativamente suaves y con fuertes oscilaciones térmicas, con periodos estivales fríos y otros de calor riguroso.
– contrastes acusados en la cuantía y bajos indices de precipitaciones.
– aridez estival sensible y contrastada: acusada aridez estival, complejidad de la precipitación estival, duración de la aridez estival.
– régimen de precipitaciones con contrastes y matices con predominio de la de invierno y primavera.

FUNCTIONALIZED MESOPOROUS SILICA IS A VIABLE ALTERNATIVE TO BENTONITE FOR WINE PROTEIN STABILIZATION

The presence of grape-derived heat unstable proteins can lead to haze formation in white wines [1], an instability prevented by removing these proteins by adding bentonite, a hydrated aluminum silicate that interacts electrostatically with wine proteins leading to their flocculation. Despite effective, using bentonite has several drawbacks as the costs associated with its use, the potential negative effects on wine quality, and its environmental impact, so that alternative solutions are needed.

Enological and nutraceutical potential of some grape varieties tolerant to downy mildew and powdery mildew

AIM: Since 2012 the Veneto Region regulation (north-east Italy) allowed wine production using 20 hybrid grapevine varieties selected for their high tolerance to downy mildew and powdery mildew. Characterized by vigour, high grape productivity and low pesticide use, these varieties are suitable to develop sustainable viticulture in mountain areas located at medium altitudes.

Genotype-environment interaction of three cultivars of vitis vinifera L. cultivated in two different environments of the Ischia island: effect on production and quality; aspects of the quality of the obtained wines

Pendant une période de trois années le comportement productif et qualitatif de trois cépages tous indigènes de la région de Campania (Italie méridionale) dans deux terroirs de l’île d’Ischia a été étudié; ceci pour obtenir quelques indications préliminaires sur le comportement productif et qualitatif des cépages et sur la qualité des vins.

From plant water status to wine flavonoid composition: a precision viticulture approach in a Sonoma county vineyard

Plant water status of grapevine plays a critical role in affecting berry and final wine chemical composition. The environmental variabilities existing in vineyard system have significant impacts on plant water status, but it is challenging to individualize environmental factors from the temporal and spatial variabilities in vineyard. Therefore, there is need to monitor the ecophysical variation through utilizing precision viticulture tools in order to minimize the separation in berry composition. This study aims at delineating vineyard into different management zones based on plant water status explained by soil texture, and utilize differential harvest to equilibrate the final berry and wine composition.

Study of fungal and bacterial laccases for the reduction of ochratoxin A content in model wine

Ochratoxin A (OTA) is a mycotoxin produced by several filamentous fungi infecting grape bunches (Penicillium and Aspergillus spp.), this toxin pass to must when grapes are crushed and later it is found in wine. Following the evaluations of the toxicity of OTA, European Commission Regulations have been promulgated introducing upper limits for OTA concentrations in various commodities (cereals, cereal products, dried vine fruit, coffee, wine, grape juice, baby foods and dietary foods for special medical purposes).
