 Although there have been suggestions that Prošek is related to the Italian sparkling wine Prosecco there are no similarities between the products either with regards to production method, style or the grapes used, and there is no relation between the origins of the two names.Because of the name similarity, on 1 July 2013, EU banned the use of name Prošek in all of their members.Croatia filed a complaint, as a croatian winegrower claimed that the wine had been produced "for at least 2000 years".
