Les sols du cru de Bonnezeaux, Thouarcé, Anjou, France

Abstract

Le cru de Bonnezeaux est une des appellations prestigieuses des vins liquoreux et moelleux des Coteaux du Layon et sa réputation est ancienne. L’INAO a effectué sa délimitation en 1953. Le vignoble est situé au nord de la ville de Thouarcé et au sud du village de Bonnezeaux, le long du versant rive droite du Layon, exposé au sud-ouest. La superficie du vignoble est de 156 ha. L’objectif de ce travail était d’une part de vérifier, sur un cru de grande typicité, les conditions géo-pédologiques, en particulier les différents types de sols, leur répartition spatiale et leur hétérogénéité, et d’autre part de comparer les sols du cru avec ceux de la zone adjacente. Une cartographie détaillée des sols a été effectuée. La superficie couverte par l’étude est de 380 ha.

Precision viticultural strategy for managing intra-vineyard variability in grape aroma using UAV-based vigour indices

In several cultivars, such as Gewürztraminer and Riesling, grape and wine aromas are determined by volatile terpenoids.

Grape ripening delaying with combined use of leaf removal and natural shading in Manto negro (Vitis vinifera L.) under deficit irrigation

The increasing frequency of heat waves during grape ripening presents challenges for the production of high-quality wine grapes. This underscores the significance of developing effective irrigation and canopy management techniques to optimize both yield and grape quality.
A field experiment was carried out during 2021 and 2022 using Manto negro wine grapes to study the effect of two irrigation strategies and different light exposure levels on grape quality. In a four-block experimental vineyard at Bodega Ribas in Mallorca, two irrigation treatments—moderate and severe deficit irrigation—were implemented. Within each irrigation plot, three light exposure treatments were randomly assigned, encompassing exposed clusters from pea size, non-exposed clusters, and shaded clusters after softening.
