[4] In 1887, his son, Robert Fulton Barr, set up a division of the original company in Glasgow, which had a much larger population.

[13] In December 2022, the company acquired Boost Drinks for £20 million from founders Simon and Alison Gray.

[16] On 14 July 1961, the Coca-Cola Company asked Lord Walker[note 1] for an interim interdict about the type of bottle used by A.G. Barr's "Kolabar", "Cydrap" and "Stilkrush" in the Court of Session.

Lord Walker refused the interim interdict, as a large part of their business could've been disturbed, additionally because Coca-Cola made no sales in the country at that point.

[17][18] A.G. Barr produces a variety of soft drinks from production sites at Cumbernauld, Forfar and Milton Keynes.
