Langres AOP Germain 180g
Langres was declared CDO (Certified Designation of Origin) in 1991 then PDO (Protected Designation of Origin) in 2012.
Effectively, the AOP dictates that it can only be made in the Bassigny and Langres communes in Champagne-Ardennes. Moreover, the milk has to come from Montbéliarde, Simmental or Brune cows that are pasture fed for a minimum of 6 months a year.
