New laws introduced by the EU and Canada require mandatory labelling of allergens in wine. Casein and skim milk are used as fining agents in wine. Unless analysis of the wine following use of these fining agents can prove their absence, the presence of milk products must be indicated on the label.
We use an enzyme-linked immunosorbent assay (ELISA) to screen wine samples for the presence of casein as an indicator of the presence of milk or milk products. A negative result means you do not need to indicate the presence of milk products on the label.
50mL sample required.
