Baiona borders on O Rosal, a sub-area which, along with O Salnés, O Condado, Ribeira do Ulla and Soutomaior make up the Appellation d'Origine Rías Baixas. Each year those wines stand out among the best white wines in Spain. Made from a basic grape called "albariña", their most remarkable features are sugar content and acidity. Other grapes used in the wine are "torrontés", "loureira", "treixadura", "espadeiro", "sousón" and "caíño".
Vine growers have recently incorporated high technology in the production process though growing, vintage and harvest techniques remain in the traditional way. Wine quality has profited from this combination.
Once made, wines go through different tests and are sensory assessed by a tasting committee. The committee decides whether the wine deserves the "Rías Baixas" label or not. "Rías Baixas" is a Galician Appellation d'Origine currently exported and promoted abroad -mainly in Germany the States and Japan.
The remaining marc is used for making exquisite typical eau-de-vie called "aguardiente", which means "burning water". The liquor is burnt with some other ingredients inside an earthenware casserole to make a kind of potion -formerly thought to be magic- called "Queimada" (burnt), the grand finale for a special dinner.
