The wine merchant Peter Joseph Valckenberg (1764-1837) bought the historic vineyards of the famous single vineyard Liebfrauenstift-Kirchenstück in Worms (Rheinhessen) during the Napoleonic secularisation in 1808. The "P.J. Valckenberg" winery developed from this. Today, the estate is still partly owned by his descendants and has since been renamed Liebfrauenstift. The Valckenberg company has the sole right to use the brand name "Madonna" for the wine Liebfrauenmilch. It is one of the most successful brand wines in the world. The company's wine trade division sells German wines from renowned wineries to 40 countries worldwide, the main market being Asia(China, Japan).
