Plot control via Satellite: precision in the vineyard and quality in wines

Cuatro Rayas Winery has launched a project in collaboration with ITACyL (Technologic and Agrarian Institute of Castile and Leon) to make a precise monitoring of particular plots of our winegrower members. All of them have a common denominator: the vigour of the vineyard. It is not always the same, that is why there are three differentiating levels: high, medium and low. This is a very precise project in determining this feature, as we have the advantage that the plots have been identified through satellite images. In this way, we can observe the evolution of the vineyard in detail, which is very important for any work done on site.

Once the plots are identified, the project envisages the establishment of two working groups to carry out their monitoring: on one side a group formed by the technical team of ITACyL and on the other hand, the technical and oenology teams of Cuatro Rayas Winery. Both groups of professionals perform the same tasks, in the vineyard and the laboratory. Including sample taking, grape harvesting and even the analysis of the material and the subsequent winemaking. That is to say, we address the process thoroughly, from the vine to the wine, but separately and taking into account the vigour of the plots. The only difference is that while the institute works with small amounts, the winery applies the same sampling criteria but on a larger scale.

What it is exciting about this job is the contrast of both working team results on the same sample. It is still early to reveal them, as the collaboration project consists of two years, but this detailed work intends to draw conclusions that will allow us to improve the future quality of the wines. Carrying out vertical sampling will show, in the future, results to be taken into account and they will have an impact even when organising the harvesting.
