This Bulgarian cheese is made from local sheep's milk (Teteven breed). You can't buy it in supermarkets or specialized food stores – it's produced in very small quantities in a village called Cherni Vit, just like the name of this unique cheese.
From May to July, the animals are milked by hand, two or three times a day. After the milking, rennet is added to the milk, and the combination is left to curdle for 2 hours. The curd is later cut and placed in a wooden box that's lined with cloth.
A wooden lid is placed on the box, and two big stones are also added for extra pressure. Once the whey has been removed, the cheese is cut into pieces, salted, then layered in a lime tree wood barrel. These barrels are left in the mountains until October, when they are strored in cellars.
