Being a lover of a negroni, this looked really interesting to to try, and jeez was it drinkable, I had 2 within the space of 30 mins.
I'm thinking it would be interesting to try grapefruit bitters, but as the other comments say, orange would be great too
Had this tonight, using 2 rums, Havana club 7 year aged and a botanical infused golden rum, Anno lady Franklin, my ginger beer of choice is Palmers, a Dorset based brewery's ginger beer (I highly reccomend).
I did add a dash of paychauds bitters as well as the angostura, because I had a hankering for their flavour, but absolutely cracking!
