Cologne: A City that Lifts the Spirits Like Italian ham The NRW officials have placed a complete ban on "storing, offering, keeping for sale, delivering, selling or otherwise bringing into circulation" the Colonia beer. LANUV compared the case with that of Prosciutto di Parma, a type of ham that can be sold under that name only if it is produced in the Italian region of Parma. Like Kölsch, this ham specialty from Parma is also protected by EU regulations The brewery in Frankfurt said it was surprised at the new ban, as its beer had been marketed since 2009. But it would not contest the ruling, it told the DPA news agency, as it would be focusing on other brands from January onward.
