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.

Application de l’Analyse du Cycle de Vie (ACV) à un domaine viticole

Since 1980, Château de l’Éclair has belonged to SICAREX Beaujolais and has been involved in experimentation for the Beaujolais vineyards. However, it is a commercial estate with profitability and quality constraints, which means that it has to meet the growing environmental expectations of consumers. Given the number of practices claimed to be environment-friendly, it is sometimes difficult to prioritize actions.

How much does the soil, climate and viticultural practices contribute to the variability of the terroir expression?

When considering the application of a systemic approach to assess the intrinsic complexity of agricultural production, the following question immediately arises

The evaluation of tannin activity in south african red wines

Astringency is an important red wine quality attribute, which can be measured both chemically and sensorially. The use of tannin activity shows potential as a valuable chemical measurement in understanding red wine mouthfeel properties such as astringency and bitterness, which is also affected by tannin structural factors, in addition to matrix effects. Tannin activity is defined as the enthalpy of interaction between tannins and a hydrophobic surface. Studies involving tannin activity have been performed since the early 2010’s, but chemosensory studies used to evaluate how structure-activity relationships change across multiple, consecutive vintages are limited. The aim of this study is to investigate how tannin activity may be linked to red wine mouthfeel, and how all these variables may change according to wine age.

Relationships between vine isohydricity and changes of fruit growth and metabolism during water deficit

The frequency of water deficits is increasing in many grape-growing regions due to climate change.

Influence of soil management and vine water regime on leaf gas exchange, berry composition and quality of Chasselas wines in Switzerland

A soil management and vine irrigation trial was carried out for 4 consecutive years from 2020 to 2023 at agroscope’s experimental vineyard in leytron (Valais, Switzerland) with the Chasselas grape variety (clone 14-33/4, grafted on 5bb). Two types of soil maintenance (bare soil with chemical weeding and sown grass) coupled with two water regimes (with and without drip irrigation from flowering to veraison) were compared in a randomized design with four replicates of 10 vines each.
