Ribeira Sacra provided wine to the most discerning palates of Rome. The Roman Empire soon discovered that the steep slopes of the Sil river produced special and unique grapes which produced excellent wines.
The so-called heroic viticulture, with vineyards placed in impossible hillsides, where peasants had to go down to harvest and then they had to shoulder charge the baskets up the hill.
This has changed little in the way but much in the background. Prestigious winemakers have put wine of the Ribeira in the place of prestige it deserves in the world.
