California-based Herzog Wine Cellars is a division of Royal Wine Corporation, a family-owned company and one of the largest producers of kosher wines in North America. Specializing in sustainable viniculture, Herzog offers more than 25 grape varieties in its award-winning wines, including brands like Baron Herzog and Jeunesse. The craftsmanship of Herzog wines is attributed to a 150-year legacy of wine making, passed down for nine generations from Czechoslovakia to the United States and now led by head winemaker Joe Hurliman.
