The Herzog family first operated a winery in Czechoslovakia. The winery was the exclusive wine supplier to Emperor Franz Joseph I of Austria, who granted Philip Herzog (1843-1918) the title of baron. Though the wines for the emperor were not necessarily kosher wines, all of the other wines were produced under the full scrutiny of kosher law.

During World War II, the Herzog winery was seized by the Nazis. The Herzogs, who stayed in hiding, immigrated to the United States after the 1948 Czechoslovak coup d'état. Living in New York City, Eugene Herzog—Philip's grandson—began working for the Royal Wine Corporation and part of his salary was paid in company shares. By 1958, he was a majority stockholder and purchased the company and started doing business under the name Kedem. The current CEO of Royal Wine Corporation is Mordechai Herzog.^[4]

Kedem wines are part of the Royal Wine Corporation, the largest importer of Israeli wines and spirits in the US.,^[5] which is in turn owned by KayCo, the largest Kosher food distributor.
