Aperol: Aperol is an Italian bitter apéritif made of gentian, rhubarb and cinchona, among other ingredients. It has a vibrant orange hue. Its name comes from apero, a French slang word for apéritif. Aperol was originally created in 1919 by Luigi and Silvio Barbieri after seven years of experimentation. It did not become widely popular until after World War II. It was first produced by the Barbieri company, based in Padua, but is now produced by the Campari Group. Although it tastes and smells much like Campari, Aperol has an alcohol content of 11%—less than half that of Campari. They have the same sugar content, and Aperol is less bitter in taste. Campari is also much darker in color. Aperol sold in Germany had an alcohol content of 15% for some time to avoid German container deposit legislation regulations, but since 2021, it has been sold with an alcohol content of 11%.
Amaro: Amaro (Italian for "bitter") is an Italian herbal liqueur that is commonly consumed as an after-dinner digestif. It usually has a bitter-sweet flavour, sometimes syrupy, and has an alcohol content between 16% and 40%. Similar liqueurs have traditionally been produced throughout Europe. There are local varieties in Germany (where they are called Kräuterlikör), in Hungary, the Netherlands, and France. But the term amaro is applied only to Italian products of this kind. Amaro is typically produced by macerating herbs, roots, flowers, bark, and/or citrus peels in alcohol, either neutral spirits or wine, mixing the filtrate with sugar syrup, and allowing the mixture to age in casks or bottles. Dozens of varieties are commercially produced, the most commonly available of which are Averna, Ramazzotti, Lucano, and Montenegro. Many commercial bottlers trace their recipe or production to the 19th century. Recipes often originated in monasteries or pharmacies. Amaro is typically drunk neat, sometimes with a citrus wedge. It may also be drunk on ice or with tonic water.
