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