(Bloomberg) -- South African wine producers need to look at increasing exports to China, which is set to become the seventh largest consumer of wine by 2012, Standard Bank Group Ltd. said. China “offers real opportunities for South African wine makers,” Willie Du Plessis, director of agricultural banking at the Johannesburg-based bank, said in an e-mailed statement today.“This is particularly crucial in light of the fact that local demand for wines has remained at very similar levels since 1993,” he said.
