Weingut Wagner-Stempel ★ 4.5
Daniel Wagner farms 25.30 hectares at Siefersheim under EU-Bio certification on porphyry-and-slate Heerkretz and Hoellberg Grosse Lage parcels at the western Rheinhessen-Nahe boundary. VDP member since 2004.
Tip: The Heerkretz Riesling GG is the estate's organic signature; the porphyry slope reads sharper and stonier than the Wonnegau limestone a 30-minute drive east.
