The Maipo Valley has a Mediterranean climate, with very little rain (mainly in winter) and hot summers making it perfect weather for the proper ripening of the grapes.
The temperature varies according to the location; for example, the upper Maipo areas are hotter and winds coming from the Andes Mountains play a role in the slow ripening of the grapes, so wines normally develop more structure, concentration and firmer tannins. In the lower Maipo areas, the temperature is mild, so in the case of red wines, they are more fruity and smooth with softer tannins. The soils are usually of alluvial origin, and have good porosity and drainage.

The Mediterranean climate offers more humid and windy conditions. The plantations are mostly between 600 and 1000 meters above river banks. Diverse micro-climates allow for the cultivation of different varietals. The Rapel Valley is first and foremost a red wine region.
