We are 100 % estate winegrowers who exclusively harvest and transform our own production. We do not buy any grapes nor juice or wine (Alsatians winegrowers represents only 22% of the regional production).
Situated on the dizzy heights of the hills of Guebwiller, in the south of Alsace, with slopes of 50° and at an altitude going from 250 to 390 metres, our vineyard is certainly one of the most breathtaking in Alsace.
Its excellent southwest, south, south east exposure gets a great deal of sunshine.
Guebwiller is the only spot in Alsace producing 4 Grands Crus. Half of our vineyard, i.e. 70 hectares, are composed of these unique “terroirs”.
The wines of our Grands Crus portray, from year to year, the ancient memory of the stones of the land.
Vosges sandstone gives subtle nuances : sometimes wine can be lightly different just for a few meters difference.
The designation “ALSACE GRAND CRU” gathers the 51 best Alsatian “terroirs”.
This classification appeared in 1983 by the “Institut National des Appellations d’Origine” (INAO) and is based on the same qualitative criteria as used in Burgundy : geology, exposure and microclimate.
In 1983, only 25 Grands Crus existed including the 4 of Guebwiller (25 other Grands Crus were classified in 1992).
The Domaine Schlumberger with 50% of the area planted with Grands Crus is very proud of our exceptional natural heritage of taste and flavour.
THE GRAND CRU KITTERLE
It is a 26 hectare area, of which 20 hectares are owned by the Domaine Schlumberger. Its height goes from 270 to 360 metres. The Kitterlé yields about 25 hectolitres per hectare.
The winegrowers who worked in this plot where steep slopes can reach 50 ° gave it the local nickname of «the calf-breaker».
This “terroir”, whose soil is volcano-sandstone, was first mentioned in 1699 and is marketed under this brand since 1830.
It is a unique site on the edge of the mountain. A rocky outcrop offering three different expositions: (southwest, south, south-east) all perched on very steep slopes of up to 50°.
Because of the soil composition, the yield cannot be important but it favours concentration of riches aromas as well as a good ageing ability.

THE GRAND CRU KESSLER
Its height goes from 300 to 390 metres.
The Kessler yields about 35 hectolitres per hectare.
Kessler is a sandstone soil, it was mentioned for the first time in 1394 and is marketed as such since 1830.
In its centre, the hill forms a small valley (Kessler) which shelters it from the cold drafts of the Northern winds.
It is an excellent spot for and and it produces sweet, charming wines.
THE GRAND CRU SAERING
This 27 hectare area, of which 20 hectares are owned by the Domaine Schlumberger.
Varies in height from 260 to 300 metres.
The Saering yields about 40 hectolitres per hectare.
This “terroir” slips down the mountain side and extends like a peninsula over the plain, forming the shape of a ring. These plains were covered by great oceans over one thousand million years ago. And so the Searing earned it’s nickname “the sea ring”.
“Ring” was also employed to talk about a Roman Camp “Seh” comes from “sehen” (meaning “to see” in German); and it is now proved that an observation camp was indeed erected there.
The stony and rather heavy soils of this Grand Cru are perfect for growing. Saering was first mentioned in 1250 and marketing began under this name in 1830.
THE GRAND CRU SPIEGEL
Its height goes from 260 to 315 metres.
The Spiegel yields about 40 hectolitres per hectare.
Spiegel (meaning “mirror” in German) was named because of the mirroring reflection of the sunrays on the clusters of grapes.
This vineyard, already mentioned in the XV Century, lies between Guebwiller and the village of Bergholtz.
Spiegel is situated eastwards; its sandy soils cover a marly-sandstone base.
Although is its speciality, it is also the special area where we pick the grapes we will use for our Late Harvest or for our “ ”.
