SOILS

In Marchigüe there are very poor and old volcanic soils. They were formed on site, without the influence of any rivers. In the native Mapuche language, "POLKURA" means yellow stone, making reference to the large amount of yellow granite spread at different depths, in the clay soils of the area. The decomposed granite, gives the wine minerality and elegance, while the clay provides body and structure.

1. This type of soil is present in two areas of the vineyard. It is a very poor soil with a high content of stones. It generates wines with a higher tannic content. Its red clays deliver body and texture to the wines.
2. Soils with higher clay content and therefore with more water retention. The wines produced in this sites, add fruitiness to the blend.
3. The "best" soils of the area to produce high quality wines. They are made of red clay, decomposed granite and organic matter. These soils are in very good balance.
4. The decomposed granite is in this case found combined with a higher content of sand and red clay is replaced with gray clay. Also here, very good quality and balanced wines can be produced.


EXPOSURE

While virtually all exposures exist in POLKURA, most of the blocks are facing south and west. The most interesting sites are those facing directly to the south, where the sun hits the vineyard in a completely oblique way. These areas receive fewer hours of sunlight and therefore reduced accumulation of temperature, resulting in much more elegant wines.

VARIETIES

Although POLKURA is a project based on Syrah, the vineyard has also other varieties planted, that work very well in the area. The reason, is adding more flavour to the blend and above all, increase the complexity of the wine.

Syrah (clones 174, 470, 300 and 100)
Malbec (mass selection)

Given the fact that there is no phylloxera in Chile, the vineyard was entirely planted ungrafted, which allows the vines to express more clearly their characteristics.
