Casa da Passarella is a winery based in the Dão region of Portugal. The producer focuses on still white wines, working with the indigenous grape varieties characteristic of this central Portuguese wine region.

The Dão region is known for its continental climate and granite-based soils, which produce wines with good acidity and mineral character. White wines from Dão traditionally emphasize freshness and structure rather than richness. Encruzado, the primary white variety of the region, is prized for its ability to develop complexity while maintaining crisp acidity and herbal, mineral notes.

Casa da Passarella's current offering includes a white wine made from Encruzado, representing the traditional white wine style of the Dão appellation.
