Geological characterization of plot belonging to the left bank terraces terroir of the Gaillac vineyard (Tarn, Midi-Pyrénées). Consequences on determination of choice of vegetative material

Abstract

Detailed geological analyses of a plot belonging to the « AOC Gaillac » area have been carried out. This plot belongs to the left bank terraces of the Tarn River which coinciding with one of the three main terroirs of the AOC area. It is localised on the rissian-aged (≈ 200 000 yrs B.P.) terrace composed of alluvial shelves crosscut by small valleys where the Oligocene (ca. 28 My) marly molassic basement outcrops. It spatially coincides with the terrace slope on which typical luvisols have developed composed by an eluvial silty-sandy horizon (up to 60 cm) overlying an illuvial pebble-sand level (up to 3 m) where clays and ferrous oxides are moderately accumulated. The slope terrace appears to be a unit with great potential for production of high quality wine because of its high topographic gradient combined with the thick permeable pebble-sand sequence, both triggering a high drainage coefficient. Further, combination of physical and chemical results – acidic pH and very low CEC – permits to select Gravesac rootstock adapted to well-drained acidic soils and Syrah/Fer Servadou climatic-adapted grapevine varieties as the most suitable vegetative material.

A pragmatic modeling approach to assessing vine water status

Climate change scenarios suggest an increase in temperatures and an intensification of summer drought. Measuring seasonal plant water status is an essential step in choosing appropriate adaptations to ensure yields and quality of agricultural produce. The water status of grapevines is known to be a key factor for yield, maturity of grapes and wine quality. Several techniques exist to measure the water status of soil and plants, but stem water potential proved to be a simple and precise tool for different plant species.

Terroir in Tasting: A sensory approach for marketing fine Australian wines of provenance as memorable experiences

Aims: Establishing an image of fine wine through the Geographical Indication (GI) system is of interest to the Australian wine sector. Beyond provenance, the sensory experience of fine wine is often linked to consumption with appropriate foods. For this purpose, studies were undertaken to understand consumer perceptions of what

The development of a simple electrochemical method based on molecularly imprinted polymers for the selective determination of caffeic acid in wine

Caffeic acid (CA) is an antioxidant of great importance in the food sector, such as wine, where it acts as a marker of wine ageing, as well as in the health sector due to its antioxidant properties and beneficial effects including the prevention of inflammation, cancer, neurodegenerative diseases, and diabetes.

Comportement hydrique des sols viticoles et leur influence sur le terroir

L’étude des relations Terroir – Vigne – Raisin est complexe. La recherche et le développement des facteurs qualitatifs qui influencent le caractère des vins sont multiples. Divers travaux mettent en évidence la relation entre l’alimentation en eau de la plante, son développement végétatif et les caractéristiques de ses raisins.

Alcohol preference and health behaviors in patients with cardiometabolic diseases: insights from the multi-center iact cross-sectional study

Recognizing the influence of alcohol preference on health behaviors is essential for developing tailored interventions that effectively promote healthier lifestyles and optimize disease management strategies in the vulnerable population of patients with cardiometabolic diseases (CMD). The present study aims to provide valuable insights into how alcohol preference relates to dietary habits and medication adherence among patients with CMD diseases.
