Frangelico
Frangelico is a hazelnut and herb-flavored liqueur (colored with caramel) which is produced in Canale, Italy. It is 24% alcohol by volume - 48 proof. It was released in the 1980s, gaining attention largely because of its unusual packaging: its bottle was designed to look like a monk, complete with a real knotted white cord around the waist. It is most commonly sold in the United States in two sizes: 750ml and 375ml
Frangelico is commonly mixed with soda, coffee or espresso. According to Barbero, the manufacturer in Italy, the name of the liqueur is based on a legend of a hermit named Fra Angelico who "created unique recipes for liqueurs." However, the bottle itself most closely resembles the habit of a Franciscan friar, while the liqueur's likely namesake, the famous painter Fra Angelico (d.1455), was a Dominican, whose robe would have been white and without the cincture.
Frangelico is made in the same manner as most nut liqueurs: nuts are crumbled up and then left to soak in the base spirit. After the spirit has absorbed the flavor of the nuts, the liqueur is filtered, sweetened, and bottled.
