The white grape variety (also Alzey S. 3983) is a new breed of Muller-Thurgau x Silvaner. The crossing was made â€‹â€‹by Georg Georg Scheu in 1927 at the Vine Breeding Institute Alzey in Rhineland-Palatinate. It was released in 1967 for cultivation in four German wine-growing areas. The name should indicate the particular qualities and is derived from the two German chancellors Konrad Adenauer (1876-1967) as for "maturity" and Ludwig Erhard (1897-1977) for "wealth". The wine is similar to the Muller-Thurgau. In 2009 the vine in Germany 33 hectares of vineyards, the trend is slightly decreasing.
