This is cross posted but hopefully I have cunningly changed the language so much you won’t see where. If you do then please PM me so I can do something about it.
Anyway, onto the thread itself - what is it that makes Irn Bru so amazingly refreshing?
It cannot be any of the following:
[ul]
[li]Sugar[/li][li]Caffeine[/li][li]Quinnine[/li][li]Ammonium ferric citrate[/li][/ul]
More or less anything else I’m willing to consider - but the above cover almost everything in it, paradoxically. So what is this trace ingredient that makes the world ok?
