I've made this with both Amaro Nonino and Amaro Nonino. Maybe I have a terrible palate, but the difference between the two resulting drinks is minor. As I don't use Nonino for much else, I'll probably stick to Montenegro in future and save some money, as Carol Smith suggests. Will definitely try this with rye next time too.

Enzonis are great. Also really like the Fall Enzoni (made with rye whiskey, red grapes - and a bit more lemon & syrup - look it up!)

New York Sour and Brunswick are both great drinks, and both are really good with a ruby port float

Thank you Simon - just ordered some, hopefully (my Flemish isn't very good!)
