Naturland-certified organic estate in Escherndorf, farming the Lump and neighbouring Muschelkalk slopes with Silvaner past 60 percent of plantings.

Tip: The Escherndorfer Lump Silvaner trocken is the estate's clearest expression of the Naturland conversion.

Weingut Zehnthof Luckert ★ 4.3

Sulzfeld am Main · Kettengasse 3, 97320 Sulzfeld am Main, Germany

Naturland-certified estate in Sulzfeld am Main farming more than 60 percent Silvaner across all four styles the grape allows, from dry Gutswein to Grosses Gewaechs.

Weingut Rudolf May ★ 4.4

Retzstadt · Im Eberstal 1, 97282 Retzstadt, Germany

Naturland-certified Retzstadt estate farming the Homburger Kallmuth, running from an EUR 10.50 entry Silvaner up through Erste Lage and Grosses Gewaechs bottlings.

Weingut Roth ★ 4.1

Wiesenbronn · Buettnergasse 11, 97355 Wiesenbronn, Germany

Naturland-certified Steigerwald estate in Wiesenbronn, working the gypsum keuper slopes below Schwanberg.

Weingut Baeuerlein ★ 3.9

Nordheim am Main · Langgasse 15, 97334 Nordheim, Germany

Nineteenth-century Nordheim family estate that converted to Bioland certification in 2020, a small, mostly word-of-mouth cellar door.
