Brew (or probably Bru from Irn Bru) is likely to work anywhere in Scotland, but you'll probably only get Irn Bru using that phrase.

Irn Bru outsells Coca-Cola in Scotland. IIRC, it's the only country in the World where Coca-Cola isn't the number one soft drink.

Ginger (which I originally thought would mean Irn Bru only - due to it's recognisible colour) actually applies to any carbonated beverage and seems to be a phrase local to Glasgow.

nope - in peru, Inca Kola is the most popular "soft drink", which at least used to be independant from coca cola when i lived there - but roumor has it that the coca-cola company bought them a while back...
really worth a try, btw...once you get used to the taste, it can be quite nice...

It tastes ultra-sweet, like the pink bubble gum we used to chew back when we were in grammar school. You can never get used to that :P

Well ++BazB,
I had to vote "Other" because in the UK we don't use terms like that, but Irn Bru is the wickedest {ahem} 'soft drink' in the known universe. For hang overs it is the best cure known to man, tastes good (if you're a Celt) and is Scotlands "Other national drink".
