The fining process is a crucial stage in the production of all wine types. In winemaking, fining agents are used for a variety of different purposes including clarification, filterability improvement, haze prevention, sediment formation, organoleptic profile improvement, colour adjustment and removal of undesirable elements or flavors. Fining involves two very important reactions: flocculation and sedimentation. Flocculation involves the molecular interactions based on charge, chemical bonds and absorption. Sedimentation involves the flocculates which are not soluble and heavier than wine.
