In general, the various places and microclimates that Chile offers for growing grapes, are more diverse and small than those we commonly mentioned. For example, to talk about the Cauquenes area (in Maule Valley) is very general, as this terroir has very specific soils and climates depending on the sector of Cauquenes we’re talking about.
Because of its size and rich diversity, it is difficult to relate this valley to a certain type of climate and soil. However, there are characteristics that are common, such as important amounts of clay and granite in its soils, especially towards the coast, and a Coastal Range rather low, which allows fresh ocean breezes to come into the valley. That is, in Maule not only Andean winds are present, but also the freshness of the coast as a key element in its vineyards.
Cabernet Sauvignon grows well in the areas of Maipo Alto, Marchigüe and Cauquenes, acquiring specific characteristics in each of these origins. The soils ideal for growing Cabernet range from those with clays (Marchigüe and Cauquenes), to those lighter ones (Maipo).
In the case of Sauvignon Blanc, the coastal area of the Sixth Region, as well as the foothills areas are appropriate for its development. And for Chardonnay, coastal areas are also recommended, but with a little more moderation in their temperatures.
