Rosolio is a type of Italian liqueur derived from rose petals, and which is often used as the basis for the preparation of other liquors of various flavors. The liqueur is prepared from alcohol, sugar, and water in the same proportion, to which is then added a rose essence.
The liqueur is common in Southern Italy. It enjoys a special popularity in Sicily, where it has been prepared since the sixteenth century and was given to house guests as a sign of good luck.
Concerti is a commercially-produced brand of the liqueur from the Amalfi Coast.
