La perception des terroirs du vignoble des Coteaux du Layon

Somló is Hungary’s smallest wine district, however one of the best producing white wines. The majority of vineyard areas are located on the slopes of Somló-hill, situated at the point where the Kisalföld meets Bakonyalja

Le terme ”Albariza” (du latin “albus“, blanc) déterminait à l’origine un type particulier du terrain calcaire, mais à présent il sert aussi à définir les sols et la bibliographie géologique actuelle le cite également pour de roches sédimentaires originaires du Neogene Betic.

Galicia is situated in the NW of the Iberian Peninsula, just north of Portugal and so sharing a mild, maritime climate, certain vine species and a number of long-standing viticultural traditions. In Galicia about 18,000 has are dedicated to wine growing, of which roughly half (46%) correspond to the 6 DOs in the area.

After bottling, the wine continues to evolve during storage. The choice of the stopper is an important factor in this evolution. In addition to the oxygen permeability of the closure, the migration of stopper compounds into the wine can also have an impact on the wine organoleptic properties. Many studies have shown that transfers of volatile compounds from the stoppers into the wine can happen depending on the type of closure used (1). Moreover, when cork-made stoppers are used, the migration of phenolic compounds from the stopper into the wine can also occur (2, 3).

Mousy off-flavor is one of the defects of microbial origin in wine. It is described as a particularly unpleasant defect reminiscent of rodent urine (a “dirty mouse cage”), and grilled foods such as popcorn, rice, crackers, and bread crust. Prior to the 2010s, mousiness was very uncommon but it has been becoming more frequent in recent years. It is often associated with an increase in pH as well as certain oenological practices, which tend to significantly decrease the use of sulfur dioxide.
