Common name in Austria for two typical institutions in connection with wine. The first is the young wine of the current (this year) vintage. On Martini, the feast and name day of St. Martin, 11 November, the wine is baptised and thus becomes a Heuriger. The Heuriger up to then becomes the "old one". Until this day, according to the old custom, one may not under any circumstances use the toast "Prost" when drinking the wine. Within the European Union, the name "Heuriger" is exclusively reserved for Austria and is regulated by wine law. Country wines and quality wines may be called Heuriger if they are made from grapes harvested exclusively in Austria. They may be sold to resellers by 31 December of the year following the harvest at the latest and to consumers by 31 March of the following year. The vintage year must be indicated on the label.
