Guinness UDV Australia, a subsidiary of the global drinks giant Diageo, plans to triple profits in less than five years and says it has an open mind about wine acquisitions. The Australian company's brands, which include Guinness, Johnny Walker whisky and Smirnoff vodka, boosted profits by 32% to A$4.1m ($2.1m), outpacing the group's worldwide drinks profit increase of 14%.
