La perception des terroirs du vignoble des Coteaux du Layon

Abstract

On peut être surpris de l’existence d’un vignoble de vins liquoreux, le vignoble des Coteaux du Layon, dans une zone septentrionale à la limite Nord de la culture de qualité de la vigne et ce d’autant plus que le cépage de ce vignoble, le Chenin ou Pineau de la Loire, est un cépage semi tardif.

La première explication est à rechercher au niveau des facteurs naturels (données climatiques et géopédologiques) permettant la réalisation de ce type de produit. Il est nécessaire de souligner ici l’importance de chaque paramètre du terroir pris dans im sens large (géopédologique et climatique) et que toute variation de l’un d’entre eux, même non perceptible en première analyse à l’homme, peut avoir des incidences déterminantes sur la qualité des vins.

La deuxième explication est dans les techniques culturales mises en place par l’homme qui, dans des conditions climatiques à priori peu favorables, doivent être conçues pour favoriser d’une manière optimum la maturité des vendanges. L’auteur s’attachera à montrer l’incidence du choix de ces techniques culturales sur la connaissance ou non des terroirs de ce vignoble.

Physical-chemical and sensory characterization of wine made with the cultivar syrah produced in a double pruning system

In recent years, the consumption of fine wines in Brazil has increased significantly, a phenomenon that is also reflected in the expansion of production to new regions. In the brazilian southeast for example, the so-called “winter wines” are being produced, through management in two cycles, one of formation and one of production, with two prunings and one harvest per year, a technique known as double pruning, with vineyards established at altitudes close to or above 1,000 m above sea level.

Do wine sulphites affect gut microbiota? An in vitro study of their digestion in the gastrointestinal tract

“Sulphites” and mainly sulphur dioxide (SO2) is by far the most widely used additive (E-220/INS 220) in winemaking and likely the most difficult to replace. The well-known antioxidant, antioxidasic and antimicrobial properties of SO2 make this molecule a practically essential tool, not only in winemaking, but also in the production of other food products. The current trend in winemaking is the reduction of this unfriendly additive due to its negative effects on health and environmental. In particular, it could cause headaches and intolerance/allergic reactions in sensitive individuals. Wine is considered one of the major contributors of exposure of SO2 in the adult population, when this beverage is included in the diet.

Drip irrigation and precision cooling reduce impact of extreme heat events during berry ripening

Context and purpose of the study. Heatwaves have become more frequent and intense in several winegrowing regions.

New training methods to manage climatic and ecological transitions in perennial fruit crops

Context and purpose. Climate change and the demand for reducing inputs, including chemical compounds, present significant challenges for perennial fruit crops like grapes and apples.
