A closure cap that is particularly suited for use with plastic containers in packaging malt based beverages such as beer and ale includes an upper portion and a generally cylindrical sidewall that depends downwardly from the upper portion. The cylindrical sidewall defines a threaded inner surface, which permits the closure cap to be threaded onto a threaded finish portion of a container. Most advantageously, the outer surface of the cylindrical sidewall is stylized to resemble a conventional crown closure. In the disclosed embodiment this is accomplished by molding a plurality of fluted ribs into the outer surface of the cylindrical sidewall. A method of packaging a beverage and a packaging assembly is also disclosed.
