The geographical area mainly benefits from an oceanic climate. However, microclimatic nuances can be observed.

Indeed, a slope, a counter-slope, the effect of the woods or a windbreak, are all situations that sometimes abruptly change the general climate data.

Windbreak landscaping is the first tool used to raise the temperature of the environment and have an increase in maturity.


The sand is essential, quickly warming the vine stocks in the spring, covering multiple substrates that nuance the landscape and production.

The sandy surfaces favor aromatic intensity: on limestone, roundness; on flint and clay-siliceous soils, the wines have an expression of “smoked and minerality”.

Sauvignon blanc reaches its full expression through sand-rich sediments, sandy deposits.

The great permeability, the good soil drainage and stone content are other assets of the terroir of Touraine Oisly. They allow for a rapid warming in the spring, ensuring the maturity of Sauvignon blanc.


“The production area of Touraine Oisly belongs to the Sologne Viticole region, located on a vast plateau between the Loire and the Cher.”

Characterized mainly by sandy soils on clay from Sologne, this terroir is perfectly suited to the production of white wines from the Sauvignon grape variety. The Sauvignon grape has made this unique territory its kingdom.

Located at an average altitude of about 105m, its relief is not marked distinctively.

To the west: Thenay

Predominantly sandy-loam soils, it is similar in context to the Gâtine areas: the sedimentary basin of shell and sand offers an original touch.

 Oisly: the central part

The area is spread out largely around the cooperative winery: Choussy, Couddes, Contres, Sassay and St Romain sur Cher. So many bell towers dominate the undulating landscape, where the long sandy ridges are filled by the vineyards.

To the east: Chémery

The parcels are scattered in an increasingly wooded Sologne: throughout the towns of Chémery, Soings in Sologne, Méhers, the mounds are more often stony.
