Fernet is a bitter Italian digestif, a member of the larger amari family. Compared to an amaro, a fernet is likely to be drier, more bitter, and typically features mint more centrally among its botanical flavorings. That said, some fernet – like Fernet Branca Menta – are so strongly mentholated that they can’t always be used interchangeably, so be sure to take a look at the “Mint fernet” ingredient too.
