La Tour-de-Peilz - Blonay - St-Légier - Vevey
A large part of the wine-growing areas in these communes is situated on what is called "calcareous clay". These soils are characterised by their red or wine colour. The rock is around 25 million years old. Soft and close to the surface of the soil, it is fissured and colonised by the roots very deep down. During the summer period, when the water supply dries up, the vines find in this rock the water necessary for the grapes to ripen perfectly. This type of soil, which contains limestone throughout its depth, also has a high clay content.
Its texture is said to be "heavy". Half the vineyards of the Vevey-Montreux appellation grow on this type of soil, unique in the vineyards of Vaud. The wines that result from it are complex, full-bodied, beautifully rich and only express their full potential after being bottled for several months.
