Foster's Group's A$3.2 billion acquisition of Southcorp and the global wine glut could ultimately prove to be the beverage group's Achilles heel, with several foreign takeover suitors understood to be sizing up the company for a potential bid, reports the Sydney Morning Herald.

The world's largest brewer, InBev, is believed to be running the rule over Foster's, with its next largest competitor, SABMiller, rumoured to be also be mulling over whether to make an A$11 billion-plus play for Australia's largest wine and beer group.

The speculation comes as Foster's was expected to announce its full-year profit, along with major revamp of its flailing wine operations and a re-launch of the beleaguered Rosemount wine label it inherited from its Southcorp acquisition.

InBev and SABMiller have made no secret of their interest in the Asia-Pacific, with both recently spending billions of dollars recently to gain strong footholds in the fast-growing Chinese and Indian beer markets.
