The treasure of the vineyard zum Sternen lies in the soil and the local climate of the lower Aare valley. The soil of the Höll site is very young and is characterised by a loam cover as topsoil. In Sennhof, the vines grow on a shell limestone soil layer. One of the oldest soils in the Jura mountains is in Klingnau: the Kloster Sion site is blessed with heavy Opalinus clay and heavily weathered shell limestone sediment, which provides minerality in the wines.
The vineyard "zum Sternen" consists of two areas: The wine nursery with the young plants and the viticulture with the self-pressing. In this combination, the motto is: from the vine to the glass - the entire depth of production is covered.
