Fernet: Fernet is an Italian type of amaro, a bitter, aromatic spirit. Fernet is made from a number of herbs and spices which vary according to the brand, but usually include myrrh, rhubarb, chamomile, cardamom, aloe, and especially saffron, with a base of distilled grape spirits. Fernet is usually served as a digestif after a meal but may also be served with coffee and espresso or mixed into coffee and espresso drinks. It typically contains 45% alcohol by volume. It may be served at room temperature or with ice. The Italian liqueur has a cult following in the international bartending community and is immensely popular in Argentina. The South American country consumes more than 75% of all fernet produced globally and, due to the product's popularity, also has Fratelli Branca's only distillery outside of Italy. As it is traditionally mixed with Coke, fernet has also contributed in making Argentina one of the biggest consumers of Coca-Cola in the world. Fernet and Coke (Spanish: fernet con coca) is so ubiquitous in Argentina that it has been described as "the country's unofficial drink".
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.
