These are the vines of the Sumoll variety that have been selected for regrafting next spring. Right now, they are in a hydration process so that they can then be placed in a cold room at about 5ºC so that they can be stored with faculties until they are regrafted.
The process of grafting varieties is to change one grape variety for another. The advantage of this technique is that we change the grape variety but keep the original roots of the vines. Therefore, we have a new variety in an already consolidated and fruitful plantation.
In our case, this is a 17-year-old plot that will be regrafted with Sumoll, a black and very Mediterranean variety, until recently forgotten, and which can also give a lot of rusticity and interesting nuances to our wines. It is characterized by a bright color and aromas of undergrowth, vegetables (fennel, thyme, carob, etc.) and minerality.
The prepiment is very easy to prepare. The shoots of the variety to be grafted are selected and can be planted between January and February, preventing the sap from already running internally. They must then be kept until around May, when the technique is carried out by specialized personnel.
On the other hand, the strains need to be hydrated. Once this procedure has been carried out, they are placed in bags in order to keep the humidity to the maximum and they are insulated in a cold room at a temperature of 5 ° C and a high humidity of more than 80%. At this time, they must also be protected from light.
The next step will be next May and consists of regrafting.
