End of an era at AG Barr

ROBIN Barr, the chairman of Irn-Bru maker AG Barr, is standing down after over 48 years at&nbsp; the company.<br /><br />AG Barr has been run by a family member for 135 years, a tradition that will end with Robin Barr&rsquo;s retirement.<br /><br />Barr is one of only two people in the world who know the secret&nbsp; recipe for Irn-Bru &ndash; which has not changed since it was discovered by Barr&rsquo;s great-grandfather over 108 years ago &ndash; and he still plans to make the journey to the company&rsquo;s headquarters in Cumbernauld each month to personally mix the 32 ingredients which create the drink. But he has said that he will eventually pass on the secret to his daughter.<br /><br />The soft drink company also produces brands such as Tizer and Orangina, but Irn Bru remains its main brand &ndash; with the equivalent of 12 cans of Irn Bru consumed every second in Scotland.
