Clarification

What it is: It consists in adding to the wine a fining agent that by means of electrostatic charge joins the particles in suspension with opposite charge, forming larger floccules that precipitate due to gravity.

What its purpose is: Its purpose is to eliminate sediments or particles in suspension. For example, egg white has an opposite charge to the tannins, therefore these two substances join and precipitate; it is added to red wines in order to eliminate the excess of tannins in suspension. Bentonites have an opposite charge to proteins and it is used mainly in whites and rosés to eliminate the excess of proteins.
