Fernet is a type of bitter, aromatic spirit that originates from Italy. It is classified as a amaro, which is a category of herbal liqueurs known for their complex flavors. Fernet is typically made from a blend of herbs, spices, and other botanicals, and it has a strong, distinctive taste that can be quite intense. It is often enjoyed as a digestif, served neat or on the rocks. In addition to being consumed on its own, Fernet is also popular in cocktails. One well-known drink is the Fernet and Coke, which combines Fernet with cola for a refreshing mix. The spirit has gained a following in various cocktail cultures, particularly in San Francisco, where it is frequently used in bars and restaurants.
