Clos Rougeard has become famous as a cult producer because of the high quality and extremely limited release of its wines – around 2500 cases annually. All of its wine is sold by allocation only, mostly to restaurants, and very little outside of France. Clos Rougeard produces only four wines: a single white wine from 100-percent Chenin Blanc called Saumur Blanc Breze, and three 100-percent Cabernet Franc reds – Saumur Champigny Le Clos, Les Poyeux, and Le Bourg. Terroir and history are especially important to Clos Rougeard. Les Poyeux comes from a parcel of land that was first cultivated in 1664. The Foucault brothers' approach to their wine is fundamentally one of minimum intervention, extremely low yields, no chemicals or pesticides, hand-harvested fruit, natural yeasts, no filtering, no fining, and gravity bottling after up to 24 months in oak.
