Rudolf May produces Silvaner from Franken, Germany's largest white wine region. The winery's portfolio centers on this regional signature grape, which thrives in the region's distinctive limestone and marl soils. Der Schäfer Silvaner Reserve, Der Schäfer Retzstadter Langenberg Silvaner, and Himmelspfad Silvaner GG represent the winery's core offerings. Silvaner from Franken typically expresses mineral precision and subtle fruit character, with the structure to age. These wines have been assessed by Wine Advocate, Falstaff, and Decanter.
