Which DOC is recognized for producing wines that include both red and white varieties?

Dao DOC is recognized for its production of both red and white varieties, making it a region that showcases the diversity of Portuguese wine. The Dao region is situated in central Portugal and is known for its distinct climate and terroir, which allows for a variety of grape types to flourish. This includes the production of notable red wines primarily from the Touriga Nacional and Tinta Roriz grapes, as well as high-quality whites made from varieties such as Encruzado and Bical.

The other regions mentioned, while also significant in their wine production, tend to have a more defined focus. The Douro DOC is renowned primarily for its fortified wines, especially Port, although table wines are produced. Bairrada DOC is famous for its red wines made from the Baga grape, with white wine production being less emphasized. Vinho Verde DOC primarily focuses on producing light, fresh white wines, although it does have some red and rosé wines; however, its reputation is predominantly built around white varietals. Thus, Dao DOC stands out for its balanced emphasis on both red and white wine production.
