Fernet-Branca is an Italian brand of fernet — a bitter, aromatic amaro built on grape spirit and a formula of 27 herbs.
Another fernet
The only true replacement. Luxardo Fernet, at 40%, is nearest and drier still. Fernet-Branca itself has about 25 g of sugar per liter. Where fernet is the base, as in Fernet and Cola, nothing else will do.
Where fernet is a barspoon or two for bitterness, a dry, very bitter amaro will do in the same amount, minus the menthol. Most amari are far sweeter and less bitter than fernet.
The same house's mint version, at 28% and about 320 g of sugar per liter. It makes the drink minty and much sweeter. If the drink has syrup, it will need less.
At 39% it is stronger than most amari, and it spends a year in oak.
