In 1998, Gerard Perse, who already owned Chateau Monbousquet purchased Chateau Pavie. The 42 hectare St. Emilion vineyard of Chateau Pavie is truly three unique and different terroirs. Each also has its own microclimates. There exists serious layers of limestone, deep clay deposits of clay and at the lower portion of the vineyards, you find sand, clay and gravel. The terroir of Pavie does not promote early-ripening. In fact, Chateau Pavie is often one of the last St. Emilion estates to finish harvesting.
