Single-layer designation occurring several times in Germany. The Celtic term Lay (Ley) means "rock" or "slate rock" and refers to the rocky subsoil. So, strictly speaking, Schieferlay is a pleonasm (like "white mould").
The vineyards are mainly oriented towards the east, in smaller side valleys towards the south to southwest. The steep vineyards cover 21 hectares on mainly greywacke soils interspersed with sloping loam. The majority of the grapes grown here are Pinot Noir, Blauer Portugieser, Domina, Frühburgunder, Regent, Grauburgunder (Pinot Gris), Kerner, Müller-Thurgau and Riesling. The Bertram Julia, Deutzerhof, Kreuzberg, Riske Erwin and Riske Reinhold wineries, for example, have shares in the site.
