Where uses "ginger"? That's a new one for me.
We also use the word "juice", which I feel reflects badly on our diet.
Aside from being orange, I don't have recollections of a very gingery flavor tho...
I do recall there being a "spicy" variant a few years ago that did taste a bit like ginger but, as I can't stand Irn Bru at the best of times, I don't recall the details.
