our Terroirs 

The vines intended for the Trois Chateaux line are located around the village of Husseren les Châteaux at an altitude of 400 meters. It is made up of different terroirs predominantly of clay-limestone and sandstone. These fresh and late ripening terroirs give the wines a lively, mineral expression, characterized by a good acidity. The ages of the vines are between 25 and 75 years.
The soils intended for the MosaïK line are generally bordering the Grands Crus, exposed east/south-east, they are rich in loess and have very fine yellow silts, sand and limestone, which is porous and permeable, with a good capacity of water retention.
The Grands Crus represent 30% of the grapes vinified by Kuentz-Bas.

Grand Cru Pfersigberg

The hills of this vineyard are exposed east/south, nestled behind the alsatian mountains, benefiting from maximal sun exposure. The Pfersigberg is composed of marl-limestone soil, with various white/yellowish pebbles of the jurassic era and hard muschelkalk. 

Fossils can easily be found in the soil, and in between can sometimes be found, layers of sandstone (yellow sandstone of Rouffach).

Rich in limestone, easy to assimilate by the plants, the clay helps to fix micronutrient fertilizers. This forces the roots to dive deeper into the soil in order to find the nutrients they need.

The water retention is average, which makes the grapes reach maturity early.

This terroir produces wines of great finesse, that are powerful, well structured, fat, spicy and has a fantastic ageing potential !


Grand Cru Eichberg

Located south/south-east, at 340 meters in altitude, the Eichberg is naturally protected from rain by the Vosges mountains, and benefits as a result from a dry and hot microclimate.

The clay-limestone based soil is composed of limestone conglomerates and marl-oligocene with boulders remaining from the tertiary age, which can be found among the sandstone pebbles, sometimes resulting in a more siliceous (quartz) soil, quartzite pebbles, white coated marl or sandy clay.

The soil is characterized by good water retention. It is airy and rich in minerals. It produces powerful wines, with excellent aromatic complexity, that are full-bodied and balanced by a refreshing acidity.

Grand Cru Geisberg

The soil of choice for the Riesling, the Geisberg is located in Ribeauvillé. With its 8.53 ha, this is one of the smallest Grands Crus in Alsace but one of the grandest by its terroir !

A soil made of limestone and sandstone marl, rich in mass of fallen rocks and dolomites fragments. Vertiginous slopes allows us to cultivate a great Riesling, complex and powerful, with a remarkable delicacy.


Grand Cru Kirchberg of Ribeauvillé

The Grand Cru Kirchberg de Ribeauvillé benefits from a South-South-West exposure which, associated with a very marked slope, provides excellent sunshine at the time of maturation. Composed of compact marl and limestone, the soil is very stony.

This terroir gives wines of great precision, the limestone brings a great tension while the rigorous climate and the marl give it a beautiful density and a remarkable balance.
