Krug was established in 1843 by Johann-Joseph Krug, a German immigrant from Mainz on the Rhine. In relative terms, this makes it a middle-aged to young house, compared to the old houses in Champagne, several of which have been going for more than ten generations. Johann learned his trade at Champagne Jacquesson for nine years before setting up Krug at Reims. His son, Paul continued the family business, who was succeeded by his son, Joseph Krug II in 1910. Joseph's nephew, Jean Seydoux, took the reins in 1924. Jean Sedoux, together with Paul Krug II are generally credited with creating the Krug style with the now defunct Private Cuvée. In 1962, Henri Krug took over the house, and he is still largely responsible for the winemaking decisions here, along with Eric Lebel.
The house owns 20 hectares of vines in Aÿ, Le Mesnil, and Trépail. They get the rest of their grapes from long-term contract growers. Unlike other négociants, Krug's growers consider themselves part of a long-standing prestigious group that openly reveal Krug as the destination of their grapes.
Aÿ supplies the Pinot Noir which goes into the non-vintage Rose, and Le Mesnil produces the Chardonnay which makes up the Clos du Mesnil Blanc de Blancs vintage. As far as prestige houses go, Krug owns a relatively small proportion of vineyard.
