The production of cheese in the Valdeón valley dates back to pre-Roman times, being made at that time with goat's milk as raw material. During the 19th century, cheese production was one of the main occupations in the area, since the production of milk from the cattle that grazed on the high-altitude sheepfolds during the summer was transformed into cheese in the cabins at the top or was transported to the villages of the valley. Due to the important natural barriers that delimit the valley, it has a microclimate that favors the development of the microbial flora that characterizes these cheeses.[4]
