The importance of racking for the success of the wines of Fattoria Selvapiana
When we talk about winemaking we have to think of a series of phases that must be carried out methodically but at the same time are never the same, in fact many factors change with each harvest and must be taken into consideration. And this is even more true if wines are produced respecting the territory and seasonality.
The racking is one of those phases whose importance is often underestimated, but it has a very specific meaning and is anything but improvised. Specifically, racking allows the elimination of sediments from the liquid obtained from fermentation, that is residues of skins, grape seeds, but also yeast and more.
These substances have different specific weights and the lighter ones continue to remain, slowly depositing on the bottom with the passing of the months, and this is why at the Fattoria di Selvapiana we carry out up to three, to obtain a limpid, clear and stable wine. We use the Air Transfer technique, which consists of pouring the wine into an open container placed lower down, an action that promotes the oxygenation of the wine, protects from any reduction problems and eliminates unpleasant odors caused by fermentation.
About a month after the end of the vinification, after the pressing phase, we proceed with the racking in order to clean the wine from the lees over time. This first racking of the wine has the purpose of eliminating the lees that have gone to deposit on the bottom of the container.
In Selvapiana, after the two fermentations, we have the tradition of carrying out two more rackings in order to be able to refine the wines as clean as possible.
It is important to carry out this step with extreme care and attention to avoid alterations in the wine. This phase is very delicate and requires a lot of time and attention to be carried out in the correct time and manner.
At the end of winter or early spring the wine must be racked again. It is important that this racking is done before the hot season arrives, a period in which it is always inadvisable to make the wine undergo “displacements” that could alter its chemical state. Also in this case our experience and technical knowledge allow us to avoid the use of adjuvant or stabilizing substances.
Generally in white and young wines the process ends here and bottling is carried out, while in the red and white ones destined for aging, further annual rackings are carried out in the spring, again to preserve color and properties.
