Bjoern and Tobias Knewitz took the 25-hectare Appenheim estate into EU-Bio organic conversion across the calcareous Kalkmergel Hundertgulden and Gewuerzgaertchen parcels. VDP member since 2021.
Tip: The Hundertgulden Riesling GG is the estate's headline organic site; pair it with the Steinacker Chardonnay to read the Bingen-Bereich Kalkmergel terroir.
Address: Rheinblick 13, 55437 Appenheim, Germany, Rheinhessen
Christian and Matthias Runkel farm 23.5 hectares at Appenheim under EU-Bio certification across the calcareous Kalkmergel Hundertgulden, Gewuerzgaertchen and Steinacker parcels. VDP member since 2019.
Tip: The Steinacker Spaetburgunder GG is the estate's most under-the-radar organic bottling; pair it with the Hundertgulden Riesling for the Appenheim Bingen-Bereich house style.
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.
Christian and Matthias Runkel farm 23.5 hectares at Appenheim under EU-Bio certification across the calcareous Kalkmergel Hundertgulden, Gewuerzgaertchen and Steinacker parcels. VDP member since 2019.
Tip: The Steinacker Spaetburgunder GG is the estate's most under-the-radar organic bottling; pair it with the Hundertgulden Riesling for the Appenheim Bingen-Bereich house style.
Jochen Dreissigacker farms approximately 30 hectares at Bechtheim under EU-Bio certification, with Riesling and Silvaner from the Wonnegau Geyersberg and Morstein slopes and a small Burgunder programme. Independent of VDP.
Tip: The Morstein Riesling is the estate's most accessible Wonnegau organic bottling; pair it with the Geyersberg Riesling to read the Bechtheim-Westhofen calcareous arc.
Volker Raumland farms 11.7 hectares at Floersheim-Dalsheim under EU-Bio certification, producing traditional-method German Sekt from Pinot Noir, Chardonnay, Riesling, Weissburgunder and Pinot Meunier on long lees-ageing.
Tip: The Triumvirat Brut Nature is the estate's signature; the EU-Bio Pinot-and-Chardonnay base reads in the long-lees-aged dry sparkling style.
Kai Schaetzel works the 14.1-hectare Nierstein estate under Demeter certification with extended skin-contact and spontaneous-fermentation techniques on the Reverse Riesling and the Roter Hang cuvee. The low-intervention frame is the modern Roter Hang signature.
Tip: The Reverse Riesling is the estate's natural-wine signature; the extended skin-contact reading of the Roter Hang style sits a long way from the dry GG mainstream.
Philipp Wittmann's respekt-BIODYN cellar in Westhofen uses no animal-derived fining agents on the dry Riesling range, working spontaneous fermentations and unfined-or-bentonite-only clarification across the Wonnegau Grosse Lage Riesling bottlings.
Tip: Ask the cellar team whether a specific cuvee was bentonite-fined or unfined; Wittmann does not pursue formal vegan certification but the entire dry Riesling range is animal-product-free in practice.
