Federspiel is a designation of ripeness for dry wines, a term used exclusively by members of the Vinea Wachau. Federspiel wines must be unchaptalized and fall between 11.5 and 12.5% ABV. The grapes are hand-harvested, typically in October, and are sent directly to press where they spontaneously ferment in stainless-steel tanks.

Steinriegl is planted to Riesling and is Prager’s only vineyard west of Weißenkirchen. The exceptionally steep, southwest-facing site has a cool mesoclimate due to its proximity to the forest, and its soil is a unique “kalksilikatmarmor,” a limestone silicate marble rarely found elsewhere in the Wachau. Bodenstein produces both an earlier-picked Federspiel and a later-picked Smaragd.
