El Rapolao is the work of Raúl Pérez, one of Spain's most admired natural winemakers, whose La Vizcaína project is dedicated entirely to old-vine Mencía from the steep slate hillsides of Bierzo. The name 'Rapolao' is local dialect for rough, rocky terrain — an apt description of this single parcel at 700–800 metres altitude, its northeast-facing slate slopes home to organically farmed vines between 50 and 100 years old, trained in the traditional gobelet style.

In the cellar, Pérez works with characteristic restraint: whole-bunch or partial whole-bunch fermentation with indigenous yeasts, ageing in large old oak foudres, no fining, no filtration, and minimal sulphur. The result is a Mencía of exceptional purity and freshness — violet, wild cherry, graphite and crushed slate woven together with silky tannins and a mineral precision that speaks unmistakably of altitude and ancient rock. Awarded 95+ points internationally, El Rapolao stands among the finest expressions of what Bierzo's hillside Mencía can achieve.
