The Portuguese region of Beira Baixa produces some of the country's best known traditional cheeses. The region has a long history of agriculture, and its granitic soils and healthy pastures make it the perfect place to create rich, tasty cheese. Beira Baixa cheese is a semi-hard cheese made from sheep’s milk, and it comes in three cheese types: Castelo Branco cheese, Beira Baixa spicy cheese, and Beira Baixa yellow cheese.
Two methods are used to produce this cheese – ovelheira, using vegetable rennet (Castelo Branco cheese), and cabreira, using animal rennet (Beira Baixa cheeses). The Castelo Branco variety is semi-hard and yellowish with an accentuated, slightly spicy flavor.
