In 1992, Castlemaine Perkins was acquired by Australian beverage and food company Lion Nathan, who in turn were taken over by Japanese beverage conglomerate, Kirin, in 2009.
In March 2016, XXXX Bitter was reduced from 4.6% to 4.4% alcohol by volume (ABV).
XXXX is still being served from wooden barrels at the Breakfast Creek Hotel in Newstead, Queensland.A second theory is that the cartoon is modelled on a well-known dwarf who sold newspapers in the inner city suburb of Fortitude Valley in the late 1920s.The true identity for the inspiration behind the cartoon remains a mystery. An advertisement campaign from the 1980s and 1990s featured the tagline "Australians wouldn't give a XXXX for anything else." Most beers under the XXXX label are sold in Australia as 375 ml cans (tinnies), 375 ml bottles (stubbies) and 750 ml bottles (tallies or long necks), on tap (in most Queensland pubs but also to a lesser extent throughout the rest of Australia) and all bottles have twist top lids.At 3.7% alcohol, the British brewed XXXX was somewhat weaker than most of the Australian variants.Castlemaine XXXX was withdrawn from the UK at the end of June 2009 when In Bev's licensing agreement expired.
