Tinta Barroca is a red wine grape variety grown mainly in the Douro Valley of Portugal. It is mostly used to make Port, as it has naturally high sugar levels and is well suited for fortified wine production. It is the third most widely planted variety in the Douro and is often used as a blending component, but it is not known for producing varietal wines of distinction. However Tinta Barroca is also grown in South Africa, where it has evolved into a trademark style for some vineyards of the Western Cape. It is also used to make Port-style fortified wines.
