This lamb comes from the Bordaleira breed, which has been raised in the districts of Coimbra, Guarda, and Viseu for centuries because of the quality of the milk it produces. The most famous product made with Serra da Estrela milk is Serra da Estrela cheese.
During the summer, these sheep graze on the open meadows where they feed on wild grasses and herbs, while they are usually kept inside during the winter. The meat of the Serra da Estrela is particularly tender, succulent, and juicy, and has a delicate taste and complex aroma.
