Landscapes of Vines and Wines Patrimony – Stakes – Valorisation

Abstract

The interaction between wine and landscapes is of an unsuspected richness. On the one side, the vineyards form part of the landscapes which they model. On the other side, the wines are related in their perception to the image of a region, a landscape and are at the origin of a cultural richness. The first International Conference on « Landscapes of Vines and Wines », that was organised from 2 to 4 July 2003 in Fontevraud (Loire Valley, France), was based on the resolutions enounced during the 4th International Terroir Symposium of Avignon (June 2003) and is integrated within the framework of the activities of the experts group « Viticultural Zoning » of the O.I.V. The goal was to optimise wine production and landscape quality not only from a technical and scientific point of view, but also from a tourist and cultural one. It was especially based on the fact that the Loire Valley is registered on the list of the World Inheritance of Humanity by UNESCO. The Fontevraud Chart, published at the Symposium, poses the principles of the environmental quality and the cultural, tourist and economic valorisation of viticultural landscapes within the framework of an international network of perennial and durable excellence. This chart, animated jointly by « InterLoire » and « Mission Val de Loire » is supported by the European Union and federates seven sites listed as World Inheritance of Humanity by UNESCO.

Reduced bunch compactness in a clone of Tempranillo associates with a complex reciprocal translocation detected by long-read sequencing genomics

Grapevine cultivars are vegetatively propagated to maintain their varietal attributes. However, spontaneous somatic variation emerges during prolonged periods of vegetative growth, providing an opportunity for the natural improvement of traditional grapevine cultivars. Notably, reduction in bunch compactness is a favorable trait in viticulture, offering advantages such as decreased susceptibility to bunch fungal diseases, and a more uniform ripening of berries. To unravel the genetic and developmental mechanisms behind bunch compactness variation, we examined a somatic variant of Tempranillo Tinto cultivar with loose bunches. We found that the mutant clone exhibits a ~50% reduction in pollen viability compared to typical Tempranillo clones.

The wine: a never-ending source of H2S and methanethiol

Volatile sulfur compounds (VSCs), mainly hydrogen sulfide and methanethiol (H2S and MeSH), are the responsible for reductive off-odor in wine.

Grapevine genotypes differ in xylem vessel occlusion after winter pruning 

Grapevines are continually wounded throughout their cultivation especially during winter pruning. Grapevines respond to wounding by occluding xylem vessels with gels or tyloses to limit pathogen attack and dehydration of the tissues. Although the production of xylem vessel occlusions has been studied in grapevine, to date we have no knowledge of whether different genotypes respond differently. The objective of this study was to characterize the genetic variation in xylem vessel occulsions in five different scion genotypes pruned at different dates.

Study of the vine performance and the wine composition of Tannat on the terroir of Colonia del Sacramento – Uruguay

Grape-growing terroirs were defined according to the method proposed by Falcetti and Asselin (1996) near of Colonia de Sacramento, a city of Uruguay situated on the left of the “Rio de la Plata”.

New markers for monitoring “fresh mushroom aroma” in wine: A dual approach using microbiological and chemical tools from the vineyard to winery–A synthesis of recent research advances

The ‘fresh mushroom off-flavour’ has been recognized by the wine industry as an emerging defect since the 2000s. For many years, this off-flavour was not specifically characterized and rather grouped under ‘earthy’ and ‘musty’ taints. However, it has become increasingly problematic due to its rising prevalence. In some vineyards, incidents of this off-flavour now occur as frequently as once every five years. This trend may be associated with climatic changes affecting regions that are more prone to warm and wet seasons.
