(ANSA) - Rome, August 29 - Italian wine producers are predicting a season of "excellent quality" in 2011 although total wine volume may be 5% lower due to high summer temperatures. The forecast came from the Assoenologi, the Italian association of enologists, and is expected to give wine producers a boost after a recent fall in domestic wine sales. "There is a certain homogeneity in almost all the regions in 2011, but it's possible we'll produce a high-quality harvest," said Giuseppe Martelli, director general of Assoenologi.
