Rabarbaro Zucca is an Italian amaro that hails from Milan. As evident from its name—rabarbaro stands for rhubarb—the main flavoring is a rhubarb macerate, while other ingredients include a secret blend of herbs, fruit, and spices.
The result is a dark-brown, richly flavored liqueur with a herbal aroma and excellent balance of sweetness and bitterness. While the first part of the name is a reference to the main ingredient, zucca—which stands for pumpkin—is a reference to its inventor Carlo Zucca.
The story says that the drink was inspired by an old family recipe he found on a small hand-written note. He started commercial production in 1919. Rabarbaro Zucca is usually enjoyed as an aperitif. Serve it neat, on the rocks, or topped with tonic or sparkling water.
It could also work well as a cocktail ingredient.
