The vineyards that give rise to our Montes Alpha M are located in the Colchagua Valley, at our Finca de Apalta estate. The soils are of granitic origin and vary in clay content, depth, organic matter, and in particular, the quantity of rocks and stones found in them, which range from fluvial to glacial in origin, highlighting the great diversity of soils. Some areas also show the influence of the nearby Tinguiririca River, while higher up, material from the long-term erosion of the valley’s mountainside is evident. The soils are deep in the flatter areas and thinner at the foot of the mountains, where the Cabernet Sauvignon is planted on 30º slopes. The vines are trained in a simple double Guyot system and planted at a density of 5,555 vines/hectares (2,250 per acre), giving yields of approximately 3.5–4.0 tons/hectare (1.4–1.6 ton/acre). This produces wines with characteristic concentration, good structure, outstanding colour, and excellent ageing potential.
