"Seo IRN BRU."
Translation:This is IRN BRU.
Whisky is known as Scotland's national drink. Irn Bru is considered as "Scotland's other national drink".
Irn Bru is a carbonated soft drink, and the No 1 best selling soft drink in Scotland. Scotland is the only free trading country in the world where Coca Cola is NOT the No.1 soft drink.
Because it's a Scottish made soda. It used to be that Coca Cola was the top soda that sold the most units in many countries. In Scotland the top selling soda was Irn Bru. I don't know if that's still the case since they changed the recipe to use sweeteners rather than sugar. It's tricky to find it outside of Scotland, even in other parts of the UK and harder still in Europe (if they know what it is).
