Caractéristiques édaphiques et potentialités qualitatives des terroirs du vignoble languedocien

The genetic material preservation is a priority issue in winemaking research. The recovery of minority grape varieties can control the genetic erosion, contributing also to preserve wine typical characteristics. In D.O.Ca. Rioja (Spain) the number of grown white varieties has been very limited, representing Viura the 91% of the cultivated white grape area in 2005, while the others, Garnacha Blanca and Malvasía riojana, hardly were grown. For this reason, a recovery and characterization study of plant material was carried out in this region. In 2008, the results obtained allowed the authorization of three minority white varieties: Tempranillo Blanco, Maturana Blanca and Turruntés.

A good knowledge of the soil physicochemical properties, as well as its ability to retain and put the necessary water available to the plants, is essential when it comes at the design of an irrigation plan.

Nowadays biodiversity loss is considered as a prior environmental issue. Agricultural landscapes are particularly concerned, mainly through the specialization and intensification of farming activities which lead, at a larger scale, to landscape simplification. Landscape management would be a good means to halt biodiversity loss, but large-scale studies remain rare. The life+ project BioDiVine aims to understand biodiversity dynamics and promote sustainable conservation actions at this scale in viticulture.

Sensory analysis is an essential component of oenology, offering valuable insights into wine quality that influence decision-making in viticulture and winemaking.
