A highly terroir-driven white from the Douro, sourced from very old vineyards planted at 650–700 metres on poor micaceous schist soils. Led by Rabigato, with Códega, Gouveio and Viosinho Dozelino Branco, it combines citrus, sour peach, white flowers and fresh fennel with a distinctly stony, saline character. The altitude and extreme day-night temperature variation bring remarkable freshness and precision to the wine.
Spontaneous fermentation with indigenous yeasts and a long élevage in used 228-litre French oak barrels, on the full lees without bâtonnage, give the wine considerable texture and depth while keeping the oak integrated. More intense and structured than Xisto Ilimitado, it is a serious, complex white with firm acidity, velvety texture and a long mineral finish — a striking expression of old-vine Douro terroir.
