Vieux-Boulogne

Vieux-Boulogne (also known as Sablé du Boulonnais) is an unpasteurized, unpressed cow's-milk cheese made in the département around the town of  in France.

This artisanal cheese is square in shape, at around 11 centimetres across and 4 centimetres high, and weighs up to 500g. It has a soft, elastic central pâte, surrounded by a moist, red-orange washed rind that is washed in during production. The cheese is pre-salé (pre-salted).

Vieux-Boulogne is famed for its strong smell, and in November 2004 was found by researchers at to be the "smelliest" of 15 French and British cheeses that they tested. A followup test done by the same institution using "electronic nose" sensors in March 2007 reaffirmed Vieux-Boulogne's status as the world's "smelliest" cheese.
