It is the downstream extension of the Grand Cru Hatschbourg. It consists of heterogeneous loess deposits (aeolian and limestone silts). The Kastelweg has predominantly clayey structures, with loess rich in limestone on the surface. Its southern exposure, in hillsides, favors progressive and regular maturities (north latitude) and early at the end of fruiting cycles, which is an asset in cold years. The style of our Kastelweg wines? Powerful (aroma of opulent fruits), fatty (clays), and long in the mouth when yields are controlled (60hl / ha), thanks to a mineral structure. It is a terroir that produces wines for ageing.
