Gloeckelberg.

The Grand Cru Gloeckelberg, mainly located in Rodern with a small part in Saint-Hippolyte, has sloping hillsides facing south and south-east, creating a funnel effect for air circulation. Shaped by tectonic stresses to the west of the Vosges fault, this terroir has marked relief and fault rejections.

The soil of Gloeckelberg is mainly composed of granite. At the top, schistose and sandstone debris mingle with granite, resulting in a low useful water reserve, while at the bottom of the slopes, the accumulation of colluvium favours a better water supply.

The microclimate of central Alsace, sheltered by the Vosges mountains, means that the region receives less rainfall. With rainfall of between 600 and 700 mm per year, the Gloeckelberg enjoys ideal exposure, steep slopes, no obstacles to the east and moderate altitude, creating excellent thermal conditions for the early ripening of the Grand Cru grapes.
