Not open to the public.
AG Barr are a national business, founded in 1875 and with strong roots in Scotland and the north of England. Their portfolio includes Strathmore water, Rubicon tropical and Rockstar energy drinks. Most famously, they make Irn Bru. The head office and factory aren't open to the public, but every year they participate in Lanarkshire’s ‘Doors Open Days’ scheme and welcome 300 or so civilians in to see where the magic happens.
