Ostatu is located in an 18th-century structure in the foothills of the Sierra de Cantabria range which was a former country inn (or hostel, offering hospitality; the origins of the name Ostatu) which travelers would stop for nourishment & rest on their way across the mountainous Basque Country. 85% Viura / 15% Malvasia, Ostatu Blanco is an incredible value & introduction to their range of wines. The secret lies in the high-altitude, bush-trained vineyards of indigenous viura & malvasía grapes coming from the villages of Samaniego, Laguardia, and Leza in Rioja Alavesa at an altitude of 580m.
