The grape variety originates from Germany. It is a white wine variety, so the name is misleading. The multi-layered berry colour plays between grey, pink, red to violet, but the depth of colour is not sufficient for pressing a red wine. It is probably a colour mutation of the Silvaner variety (Grüner Silvaner and Roter Silvaner). The Franconian winegrower Johann Kaspar Steinmann (Schloss Sommerhausen winery) discovered a vine of Blauer Silvaner in a vineyard in 1964. After many selections, 12 years later he provided a clone to the Bundessortenamt for register testing. This examination was completed in 1984 and the variety Blauer Silvaner ST25 was entered in the variety list as a yielding variety. This particular clone is the property of the Steinmann Vine Nursery, which is also registered as a conservation breeder. The medium to late ripening vine yields fruity white wines with herbal aromas. In Germany, it is cultivated by the vineyards Kloster Pforta (Saale-Unstrut), H. Deppisch and Schloss Sommerhausen (Franconia), among others. In 2018, 29 hectares of vineyards were designated in Germany (D-STATIS).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
