One of the first wineries to plant Scheurebe commercially and make high-quality wine from the grape was Weingut Annaberg in the Pfalz. With their successful plantings and vines, they popularized Scheurebe in the 1940s and 50s. Many of today's major plantings around Germany were originally taking from Annaberg cuttings. Today, Annaberg is a much different winery than it was in the middle of the 20th Century; the building has been turned into a hotel, and they are known for a high-quality restaurant on the premises. They still make some wines, but are no longer known for Scheurebe.
If you follow auctions closely, sometimes you can find an old bottle of Annaberg Scheurebe Trockenbeerenauslese floating around from the 1950s.
