What minimum percentage of the blend must the Glera grape constitute for a wine to legally be named Prosecco?

Answer

85%

The identity of Prosecco is legally tied to the Glera grape variety. For any wine to legitimately bear the name Prosecco, the Glera grape must constitute a minimum of 85% of the total blend used in its production. This high requirement ensures that the resulting wine carries the characteristic flavor profile associated with this specific grape. If the percentage of Glera falls below this threshold, the wine must be classified under a different designation, even if it originated from the designated Prosecco growing zones.
