Beurre d’Ardenne (pronounced as /fr/;) is a type of butter made in the Ardenne of Belgium from cow's milk.
As a traditional product of the area, it received Belgian appellation d'origine by royal decree in 1984,[1] and received European protected designation of origin status in 1996.[2]
The areas where it is produced are within Wallonia and include the provinces of Luxembourg, Namur and Liège.[3]
To qualify, production must take place entirely in those areas, from milking of the cows, through to churning and, final maturation of the butter,[4] and may be made by churning milk, cream or a mixture of both. The final product must be of at least 82% butterfat and butyric acid.
