As the son Alexander and the daughter Carolin enterd into the family company did they also intensify the business development and marketing. A total of 14 hectares of vineyards are cultivated. The first-class wines are produced according to the highest quality standards and the latest production technology. Since 2014, at the southern entrance of Diedesfeld in the midst of the vineyards with a magnificent view, a modern vinotheque is run, which is very popular with wine lovers from near and far.
