Located on the northern outskirts of the town of Andlau, the Kastelberg extends over a small hillock, its steep slopes exposed to the south, at an altitude ranging from 240 to 300 metres. The Kastelberg is one of the rare vineyard areas established on soils of the Vosges basement. It lies on the Steige schist of the Silurian age, unique in Alsace, which has been metamorphosed by Andlau granite, outcropping on the upper part of the site, into very hard, dark-coloured hornfels, made up of quartz, mica and chlorite. The soil is hence very stony and well-drained, mixed with granitic sand at the summit of the hill.
