Which specific Italian regions must true Prosecco exclusively originate from?

Answer

Veneto and Friuli Venezia Giulia

True Prosecco production is strictly anchored to a specific geography, meaning the grapes must exclusively hail from select provinces located within the northeastern Italian regions of Veneto and Friuli Venezia Giulia. This adherence to geography is a fundamental aspect of its authenticity and is formalized through quality control designations like DOC and DOCG. Other Italian wine regions, such as Tuscany or Piedmont, are associated with different, distinct styles of Italian wine production, meaning wines sourced from there cannot legally carry the Prosecco designation.
