Traditionally produced in the Portuguese district of Bragança, butelo de vinhais is a smoked sausage made with pork meat and pork loin from Bísaro pigs. The meat is seasoned and flavored with garlic, paprika, bay leaves, and salt, and it's also infused with regional red or white wine. Vinhais sausage has a pronounced smokey aroma and a well-rounded flavor.
