The Saumagen is the estate’s crown jewel: four hectares planted on a hill of limestone, chalk and marl.
The "R" designation refers to both the rare and reserve qualities of the bottling. The wines are made in exceedingly small quantity, and they are held back for 4 years in bottle before release. The qualitative equivalent of a GG for the estate.

Two passes in the vineyard are dedicated to collecting berries of particular phenolic character: tiny, perfect, golden berries are selected for a Spätlese "R" barrel. If these barrels don’t live up to expectations, they are blended down into the lower cuvées.
