Red wines made from Castelao, a traditional grape primarily found in Portugal, exhibit vibrant acidity, moderate tannins, and flavors of red fruits, earth, and herbal notes. Often medium-bodied, these wines can be crafted in both fresh and fruity styles or aged in oak for added complexity. Regions like Setúbal and Alentejo are experimenting with Castelao, highlighting its versatility. This grape stands out due to its resilience and potential for producing food-friendly wines that reflect local terroir.
