Perhaps the most famous brand of Fernet, an Italian herbal digestivo which is bracingly bitter.
Darling of the cocktail bartending scene, this is traditionally sipped after dinner to aid with digestion but is cropping up increasingly on cocktail menus around the world. A classic inky amaro, or bitter, you'll long remember your first encounter with this chap!
For an invigorating twist on a Manhattan, try the Fancuilli Cocktail, which calls for Fernet-Branca instead of bitters.
It is also an integral ingredient in the classic Hanky Panky Cocktail, which consists of equal parts Gin and Sweet Vermouth, with a couple of dashes of Fernet-Branca.
