The estate describes its approach as making authentic wines without makeup. Winemaking relies on indigenous yeasts, low sulfite additions, and minimal intervention throughout. This philosophy extends from the vineyard to the cellar, with the goal of expressing the character of Bairrada's indigenous varieties and historic soils without masking them through heavy-handed techniques.
- Indigenous yeast fermentations only
- Low sulfite additions across the range
- Minimal intervention from vineyard to cellar
- Annual production of approximately 120,000 bottles
Baga-based reds from this estate show the variety's characteristic firm tannins and high acidity, shaped by Atlantic influences and limestone-clay soils. Whites from Bical, Arinto, Cercial, and Maria Gomes tend toward freshness and citrus-driven character with mineral definition.
