Heroic Viticulture
Grape production in the Ribeira Sacra is known as Heroic Viticulture because the steep slopes where the vineyards are planted make the work extremely challenging, and there is little possibility of mechanization.
The influence of the Sil and Miño rivers creates an ideal microclimate for grape production. Winter and spring rains ensure there is enough water for the plants to grow harmoniously and sufficiently. The production is naturally balanced and typically low.
The stone-based soils give the land a composition completely different from other wine-producing regions. Unlike other areas where soils are formed by erosion, here they are formed by the degradation of slate. The soil pH is acidic, not alkaline as in most regions around the world. There is little clay, and the soil is primarily the result of rock degradation, transforming into granite and sand.
These wines are also influenced by the Cantabrian Sea and the Atlantic Ocean: the climate's behavior is unique due to the strong maritime influence. This allows us to refer to the wines produced as Cool Wines or wines from cool climates. This influence adds an uncommon element, as the nights are cool and the days warm, but not as hot as in more continental areas. Naturally, the grapes exhibit high natural acidity and low pH levels.
