Designation French for "small banner") for an official closing sign in the form of a seal or a seal. The bottles of alcoholic beverages are also provided with a banderole. They are used in the form of a paper strip attached to the bottleneck and passed over the closure. In Austria, they were made in 1985 as a result of the wine scandal (Adulteration with diethylene glycol) introduced.
The paper strip was destroyed when a bottle was opened to prevent abuse such as refilling with a lesser wine. They served the quantity control, since they were with the nominal volume, the operating number of the bottler and a consecutive number and were for quality wines and Prädikatsweine compulsory.
