This is a polarizing cocktail. I am fine with the strong herbal character but it's a bit much for my wife. No orange juice available, unfortunately, so I added a dash of orange bitters and cut the Fernet to an ounce.
If I try this again I will cut the Fernet in half, and use Antica Formula vermouth instead of the Cocchi Torino. And make sure I have an orange to squeeze.
I think you made the same mistake as Nicola Adams above. The recipe calls for 1/12 oz (one twelfth), not 1.5 oz Fernet. I can imagine it was pretty overpowering.
