STURM is the name in Austria for the still fermenting, slightly sweet to austere tasting must on the way to becoming wine; the term in Germany is federweisser.
When the wine has not yet become wine but has moved beyond being must and sturm, it is called STAUBIGER. The designation has to do with its appearance because at this stage it is still unfiltered. It is the traditional accompaniment to goose on St. Martin's Day.
On that same day, November 11, the new wine of the current vintage (in this case 2020) is dubbed HEURIGER (this year's wine), a title it is allowed to bear for exactly one year. Incidentally, when toasting in Austria with heuriger wine, you say "Prost!" (Cheers!), whereas with sturm and staubiger , the correct term is "Mahlzeit!" (Enjoy your meal!).
