The Pinot Gris is planted on the upper part of the Heimbourg vineyard in Turckheim. Facing west, on a steep slope, it enjoys a relatively cool climate being exposed to the valley winds. At the opposite of the Rotenberg vineyard located on the other side of the valley, the Heimbourg vineyard gets a few more hours of sunshine in the evening, which probably explains why the vineyard produces more aromatic style wines. The Oligocen limestone soil is here a complex combination of old Oolithic pebbles cemented in an aggressive calcareous limestone, rich in iron (red color). The influence on the wine is tremendous.
