Vegan and Vegetarian Wines
Whether a wine is vegan or vegetarian is partly down to the actual process of making the wine, or ‘fining’.
Fining is when an insoluble substance is added to the wine to clarify or stabilise it. These substances or agents are used to remove things like proteins, yeasts and bitter molecules. They bind themselves to the impurities, which in turn allows them to be removed from the wine. Some of the most commonly used fining agents are those below, which are derived from animals or fish:
- Gelatine – an animal derived agent
- Isinglass – a fish derived agent made from fish swim bladders
- Egg Albumin – an agent derived from egg whites
- Casein – an agent derived from cow’s milk
