Colchagua Valley

Colchagua sits between San Fernando in the north and Chimbarongo in the south. The climate is Mediterranean but, like the Maipo, has cool, mid range and high temperatures according to proximity to the Andes.

Soils are derived from conglomerates (rocks composed of smaller rock particles cemented together in a mass of hardened clay and sand), breccias (stone composed of fragments of the same rocks) and tufas. They are found as far south as Colchagua in Rapel and in the Maule. They are flat and slightly undulating. They may be shallow to deep, have clayish-loam texture with good drainage or, on the contrary, drainage may be impeded by the presence of volcanic tufas.
