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.
Address: Bahnhofstrasse 33, 67591 Hohen-Suelzen, Germany, Rheinhessen
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 The Rothenberg Wurzelecht ungrafted-vines bottling carries the historical reference.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.
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.
