There is no new name for Prosecco.
Prosecco is still called Prosecco and remains a protected designation of origin (PDO) status by the European Union. This means that only sparkling wine produced in the Prosecco region of northeastern Italy can legally be called “Prosecco.”
Slovenia had proposed renaming their sparkling wine as “Slovenian Prosecco” to comply with the EU’s decision to grant Italy exclusive rights to use “Prosecco.” However, the European Commission rejected Slovenia’s proposed name in 2020, stating that it was too similar to “Prosecco” and could create confusion among consumers.
As a result, Slovenian producers are now prohibited from using the name “Prosecco” and must use a different name to label their sparkling wine.
