DO Valdeorras ★ 4.5
Valdeorras sits directly west of the Bierzo across the provincial line into Ourense, on the same Sil valley and much of the same slate. It is the Galician denomination that did most to rescue Godello from near-disappearance in the 1970s, and tasting its whites against Bierzo Godello is the clearest way to hear what the two sides of the border do differently with one grape. The drive follows the Sil the whole way.
Pours: Godello from slate soils at O Barco and A Rúa, Mencía from the Sil valley
Tip: Do Valdeorras and Las Médulas on the same day: the mine sits between Ponferrada and the provincial boundary, so it is barely a detour.
