America
The Bittermens chaps over in the USA were inspired by cream sodas and phosphates you might find in soda shops of old for their Orange Cream Citrate Bitters, which are more intensely sour and sweet, rather than having the classically bitter flavour profile of other orange bitters. Made with 5 types of orange as well as citric acid, which ought to give your drinks a bright, citrus-y kick.
