(WSJ) - Australia’s wine industry is turning sour as the strong local currency and a glut of grapes have driven export profits to a decade-low. The value of Australian wine exports fell to 1.86 billion Australian dollars (US$1.91 billion) in the financial year that ended June 30, down from a peak of just under A$3 billion in the 2006-07 financial year and the lowest figure since 2001-02, according to government export agency Wine Australia.
