The vineyards that produce the grapes for Alpha Malbec come from Apalta and Marchigüe estates in the Colchagua Valley. Both properties have soils of granitic origin with different degrees of decomposition and varying amounts of clay, depth, and organic matter. The Apalta estate is extremely diverse with zones that are highly influenced by the Tinguiririca River and others by mudslides and geological material that breaks off from the mountains above. The soils tend to be deep in the flat areas and shallower at the foot of the mountain and higher areas. The Malbec vineyards are located in zones with gentle slopes where the soils present a mixture of material from fluvial and alluvial origin, medium depths, and low moisture retention.
