The gluten-free beer uses exactly the same ingredients as regular Peroni Nastro Azzurro, including barley. A specific enzyme is added at the end of the brewing process which removes the gluten, ensuring Peroni Nastro Azzurro Gluten Free can be enjoyed by coeliacs or those choosing to lead a gluten-free lifestyle. Peron Nastro Azzurro Gluten Free has been endorsed by the Italian Coeliac Association.
