Langres is a soft cheese made exclusively from cow's milk on the Langres plateau and the Bassigny pastures in the Champagne-Ardenne region. It has a long maturation period of at least 21 days, during which the cheeses are often rubbed with brine.
On the exterior it has a white, moldy, wrinkled rind, while on the inside it is slightly soft and crumbly. The aroma of Langres is intense, the flavor is salty, and the cheese melts in the mouth when consumed. What's so special about Langres is its concave top (fontaine in French) which was originally designed to hold a small bit of sparkling wine.
