Soil management is not just a matter of order, of having a beautiful landscape to admire. It has important repercussions on the general ecosystem of the vineyard and its natural resources, as well as on the balance of the vines themselves, and therefore on the grapes we are going to harvest.Naturally it does not act alone on production: it must be integrated with all the other choices and processes of the year.
The choice of processing technique should essentially depend on the climatic and environmental conditions in which the vineyard is located, on the varieties and rootstocks used, as well as on what type of wine is produced. Viticulture is something that must always be tailor-made, there are no best choices that are the same for everyone, even though there are basic guidelines consolidated by studies and experience.
Grassing involves less expansion of the vine, fewer shoots, a smaller and less dense canopy, and lower production yields. It has also been seen that there are musts with on average higher sugar contents and with an increase in polyphenols and anthocyanins (in black grapes). However, there is a lower presence of nitrogen in the must available for the yeasts. These consequences are not so negative for a production focused more on quality than quantity.
