Wood
The use of wooden barrels is perfect for refining aging wines. In addition to the transfer of particular aromas, they guarantee a delicate oxidation, able to make the wine mature. In this way the different components merge and the wine will be more complex and harmonious. At the same time, through this controlled evolution, wine holds up better preservation and is more prone to aging and therefore more resistant to future oxidation. The contribution of oak tannins refines those already present in red wine by interacting with them, while it gives white wines a refined tannic aftertaste that they lacked. I always remember with admiration my university professor of oenological chemistry who repeated that the barriques are real reactors: the oxygen passes through the pores of the staves, in that area inside the barrel the tannins of the Oak are in contact with wine polyphenols and thus a reaction takes place, thanks also to the presence of acetaldehyde present in the wine, which allows them to merge to form complex compounds, those that we all want in a good red wine.
