There's also a thing where many regional names are used as descriptions of foods: I don't expect Neapolitan ice cream to be made in Naples, I just expect the Strawberry/Chocolate/Vanilla pattern. In general I think this tends to be a lot more controversial in Europe, with specific DPO categorizations, then in the US, where the standard is a lot more literal (ex: Americans interpret "Champagne" to be a claim about the style, while Europeans interpret it to additionally include where the product was made).
