Espresso con panna is a single or double shot of espresso topped with whipped cream.[1] In France and in the United Kingdom it is known as café viennois.[2]
In northern continental Europe, the term Wiener Melange refers to a different drink, made with foamed milk and having no whipped cream on top. In Vienna, an espresso con panna is properly called a Franziskaner, but ordering a Wiener Melange may sometimes yield the arrival of espresso con panna even in Vienna.
In France, café viennois refers to both an espresso con panna and a Wiener Melange. In Australia, a similar drink may be called Café Vienna although espresso con panna will traditionally be in an espresso sized cup, whereas Café Vienna will be served in the same size as a latte.
Historically served in a demitasse cup, it is perhaps a more old fashioned drink than a latte or cappuccino, though still very popular, whichever name it receives, at coffeehouses in Budapest and Vienna.
