Amer Picon
From The Webtender Wiki
Amer Picon, now known as simply Picon, is an orange bitters aperitif made in France. It comes in two styles: Picon Biere, intended for consumption with beer as a mixer or chaser; and Picon Club, intended for use with wine.
It is very difficult to find in the United States. A good substitute is Torani Amer.
