Morbier is an uncooked, pressed cow's milk cheese made in the Franche-Comté region of eastern France, and named after the town of Morbier in the Jura.
It's not a blue (blue-veined) cheese as you might think, as the recognizable thin black line down the middle of the cheese is actually a very thin layer of wood ash.
This line, so characteristic of Morbier, is there to perpetuate the appearance of the old cheese, which was originally made in 2 batches, each separated by this layer of ash.
If you intend to buy: Morbier has been protected by a PDO (Protected Designation of Origin) since 2002, so you can be sure of buying a quality product. Its best consumption period is from January to March.
