(Decanter) - Wine growers in the Riverina district of Australia are recovering from a series of 'unprecedented' floods, which have blighted an otherwise promising 2012 vintage. In late February, heavy rainfall across New South Wales led to a part-evacuation of the region, with rising water levels of up to one metre devastating many of the region's fruit crops. 'We acted quickly, building a levee around the winery circumference to prevent water from entering the production facility', John Casella, owner of Casella wines in Yenda told Decanter.com.
