Source-derived summary

Irn-Bru ( "iron brew", Scots: [ˌəirənˈbruː]) is a Scottish carbonated soft drink, often described as "Scotland's other national drink" after Scotch whisky. Introduced in 1901, the drink is produced in Westfield, Cumbernauld, North Lanarkshire, by A.G. Barr of Glasgow. As well as being sold throughout the United Kingdom, Irn-Bru is available throughout the world and can usually be bought where there is a significant community of people from Scotland. The brand also has its own tartan. It has been the top-selling soft drink in Scotland for over a century, competing directly with global brands such as Coca-Cola.

The flavour of Irn-Bru is known to be difficult to describe, a fact that has even been used in the manufacturers' advertising. Public surveys have turned up words such as tutti frutti, bubble gum, cream soda, and even an undertone of iron or rust that has been referred to as 'girders'.

Originally selling it as Iron Brew, the drink's makers, A.G. Barr, were forced to change the name of the drink in 1946 following a change in the law that stipulated that the marketing of products be "literally true". As the drink did not contain much iron, nor was it brewed, the passage of this legislation led the company to change the product's name to the presently used Irn-Bru. Irn-Bru has long been the most popularly consumed soft drink in Scotland, consistently beating rivals such as Coca-Cola, Pepsi and Fanta, and reportedly sells 20 cans every second throughout Scotland.

Editorial analysis

Why this record matters

The phrase “scottish carbonated soft drink” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q938806. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1901 and 1946.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
