Fining
German: Schönen (Klären) Also known as: Klärung, Schönung
Treatment with additives that bind haze and unwanted substances and let them settle, so the drink becomes clear.
In fining, agents such as bentonite, gelatine, silica sol or activated carbon are added to the drink; they bind haze particles, tannins or pigments and sink to the bottom with them. The drink is then racked or filtered.
This improves clarity, stability and taste, for example when protein haze is to be prevented. Some fining agents derive from animal products, which is why vegan drinks rely on alternatives. As residues should not remain in the final product, dosage is important. Rules apply to permitted agents and to allergen labelling.
