Vegetarian (renouncement of meat and fish) vegan (complete rejection of all animal products; in extreme cases even honey) means the renouncement of additives or products of animal origin in the winemaking process. Affected by this is the fining and stabilizing with protein-containing means like albumin, egg white or casein (vegan) or by means of gelatine and house blister (vegetarian). Although these substances are only used for treatment, residues in the wine cannot be excluded. Individual producers are responding to these consumer needs, which have become increasingly important in recent years, by including appropriate information on the supplementary label. It is not unusual for organic wines to meet the criteria for such wines.
