The association "Pro Riesling e. V." for the promotion of the culture of Riesling in Germany was founded in 1985 and is based in Trier in the German Moselle wine region. The special features of German Riesling wines and sparkling wines are highlighted through various measures such as an annual Riesling symposium, Riesling tastings, a series of publications and various documentations. Every two years a Riesling promotional prize is awarded to wine retailers, gastronomy, sommeliers and journalists. Together with the magazine Vinum, the Riesling Producer Prize is also awarded. Several hundred German wineries from all wine growing regions participate in this competition, whose wines are blindly tasted by various juries.
