A term commonly used in Austria for a wine immediately after fermentation, when clarification has not yet been completed. The name is derived from the fact that the wine is still cloudy ("dusty"). Since 2018 this has been a wine type defined by wine law. Such a wine may only be marketed as a varietal wine without any indication of a closer origin than Austria (i.e. not as a country wine or quality wine).
It must not be confused with the only partially fermented storm. The term dusty, on the other hand, refers to an extremely dry development (meaning "so dry that it dusts"). See also under vinification.
