Rabarbaro Zucca is an Italian bitter liqueur with a sweet-bitter and aromatic flavor, characterized by a strong presence of rhubarb as its main ingredient, along with a secret blend of herbs, bitter orange peel, cardamom, and other spices. It is traditionally enjoyed neat or on the rocks as an aperitif or digestif and can also be used in cocktails. The name “Zucca” does not refer to the vegetable “zucca” (squash), but to the surname of its inventor, Ettore Zucca, who created it in Milan in 1845.
