(SMH) - Heavy rain and flooding in some wine regions came too late to completely ruin the 2012 harvest, growers say, and there are early signs the oversupply of grapes may be easing. According to early estimates from the Wine Grape Growers Association, produced in response to last month's wet weather, about 1.4 million tonnes of ''smaller but sweeter'' grapes are likely to be crushed this year, down from last year's 1.56 million tonne harvest, which was heavily impacted by flooding and disease. The association's estimate is preliminary, with more comprehensive Winemakers Federation figures out in June and official data including varietal breakdowns from the Australian Bureau of Statistics later.
