Philipp Wittmann converted the 30-hectare Westhofen estate to biodynamic farming in 2004, joining respekt-BIODYN and La Renaissance des Appellations. EU-Bio since the late 1980s. The Morstein, Kirchspiel, Brunnenhaeuschen and Aulerde Riesling GG headline the range.
Tip: Book the respekt-BIODYN vineyard walk before tasting; Wittmann runs walks across the Morstein and Aulerde parcels and the farming is the point of the visit.
Address: Mainzer Strasse 19, 67593 Westhofen, Germany, Rheinhessen
H.O. Spanier and Carolin Spanier-Gillot work 50 hectares at Hohen-Suelzen under EU-Bio certification with uncertified biodynamic practice since 2005 (La Renaissance des Appellations member), across Frauenberg, Kirchenstueck and Am schwarzen Herrgott Riesling Grosse Lage parcels.
Tip: The Frauenberg CHF Riesling is the estate's biodynamic signature; the single-barrel bottling reads the Wonnegau limestone in extreme detail.
Carolin Spanier-Gillot works 25 hectares at Bodenheim under EU-Bio with uncertified biodynamic practice (La Renaissance des Appellations member), co-managed with Battenfeld-Spanier in Hohen-Suelzen. Pettenthal, Hipping and Oelberg Riesling on the Roter Hang anchor the range.
Tip: Combine a Kuehling-Gillot tasting with Battenfeld-Spanier on the same day; the two estates share co-management and the biodynamic Wonnegau-and-Roter-Hang arc reads side by side.
Erik and Carolin Riffel farm 12 hectares on the Binger Scharlachberg under EU-Bio and Ecovin (organic) certifications, with biodynamic practice but no biodynamic certifier. The quartzite-and-slate slope above the Rhine bend at Bingen carries Riesling, Spaetburgunder and Weissburgunder.
Tip: Walk the Scharlachberg slope with Erik or Carolin Riffel before tasting; the iron-rich quartzite gives a stony, smoky frame distinct from the limestone Wonnegau norm.
Johannes Hasselbach took the 23.2-hectare Gunderloch estate at Nackenheim to EU-Bio organic certification across the Rothenberg, Pettenthal and Hipping Roter Hang parcels. The Rothenberg Wurzelecht ungrafted-vines bottling carries the historical reference.
Tip: The Rothenberg Wurzelecht parcel is one of Rheinhessen's pre-phylloxera survivors; visit Gunderloch for a vineyard walk on the ungrafted vines above the Rhine.
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.
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.
