Australia - The wine industry says the major retailers are undermining efforts to recover from the grape glut. The boss of Woolworths has warned the industry to prepare for a jump in supermarket label wine sales, as the retail chain continues to grow its own brands. Stephen Strachan, from the Winemakers Federation, says that will further damage the image of Australian wine. "What's disappointing is that we do know that there's a lot of scope to grow the category, particularly for premium wine," he says.
