The vintage
In Argentina harvesting the grapes is usually carried out between the months of February and March. Nevertheless, when the grape is picked it has to show a suitable state of maturation in order to extract the highest quality from it.
Destemming
This process consists in separating the grapes from the rest of the cluster, this is known as stalk. The objective of separating the grapes from the branches and leavesavoiding bitterness to the broth during maceration.
Squeezed
After the cluster is shelled, the grapes are passed through a treadmill to break the skin of the grape. This is how the juice is extracted to facilitate the next step, but it should not be squeezed too much to avoid breaking the seeds of the grapes, which would add bitterness to the broth.
Maceration and fermentation
The extracted juice will be kept at a controlled temperature for a few days, allowing fermentation and color. In these tanks and through its own yeasts, the alcoholic fermentation process begins since the sugar from the grapes transforms into ethyl alcohol. This process duration depends on the type of wine and must take place at temperatures not exceeding 29ºC.
