For a long time, the general principle was that everything that was not expressly permitted was prohibited. Today, the most important information about a wine is regulated in EU regulations with mandatory and optional information and is listed under label. In addition, there is additional information, which serves to provide a more detailed description and thus additional information beyond the basic knowledge to be conveyed on the main label and is intended to meet the consumer's desire for greater differentiation and knowledge transfer. They do not belong to the standard information required under wine law, such as bottler, producer, origin, vintage, quality group and grape variety, but supplement it and make it more comprehensible. The overriding principle is that, according to the "misleading prohibition", such information must be "true" and "not misleading".
