The grape variety originates from Germany. It is a white wine variety, which is why the name is misleading. The multi-layered berry colour ranges from 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 submitted a clone to the Federal Office of Plant Varieties for registration testing. The variety Blauer Silvaner ST25 was entered in the list of varieties as a yielding variety in 1984. This special clone is the property of vine nursery Steinmann (conservation breeder).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
