Located on the dizzying slopes of Guebwiller, in the south of Alsace, with slopes at 50° and an altitude ranging from 250 to 390 meters, the vineyard on the mountainside is without a doubt one of the most striking in Alsace. It has the great privilege of benefiting from a triple exposure to the sun: south-west, south, south-east.
The wines from their Grand Crus (the Kitterlé, the Kessler, the Saering and the Spiegel) deliver year after year the millennial memory of the stones. The Vosges sandstone on the edge of the mountain offers subtle nuances, sometimes within a few meters. Guebwiller is the only commune in Alsace to boast 4 Grands Crus and half of the vineyard, which is 70 hectares, is made up of these unique terroirs.
Winegrowers 100% harvest, they exclusively vinify their own harvest. The seven main grape varieties are as follows: Sylvaner, Pinot Blanc, Riesling, Muscat, Pinot Gris, Gewurztraminer and Pinot Noir.
It is now the sixth and seventh generation who are at the head of the estates. The Schlumberger family originates from Swabia, a region in southern Germany, now part of Baden-Württemberg. Claus Schlumberger was the first of the family to settle in Guebwiller in the 16th century, at the time of the Abbots of Murbach.
Since 2003, the vineyard has been managed according to the principles of sustainable viticulture and in 2006, 30 hectares were converted to biodynamic viticulture. One of the central concerns of the Schlumberger family is the preservation of their fabulous heritage so that each generation can produce the quality wines that have made the international reputation of the estate.
