Amaro (Italian for "bitter") or Amari (plural) is an Italian herbal liqueur that is commonly drunk as an after-dinner digestif. It usually has a bitter-sweet flavor, 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 Compari, 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.
Amaro should not be confused with amaretto, another Italian liqueur that is sweet and traditionally flavored with the apricot pits or with the pits of other drupe fruits such as almonds. Nor should it be confused with amarone, a rich Italian dry red wine from Valpolicella.
