The company said the purchase of brands including Sterling Vineyards, Yellow Tail, Blossom Hill and Piat d'Or as well as the Chateaux & Estate Wine business in the U.S. would immediately double its luxury and "masstige" - or mass prestige - net sales revenue in that country. The deal advances a turnaround plan under Chief Executive Officer Michael Clarke, brought in last year to rethink the company's growth strategy after a disastrous foray into the U.S. saw it destroy thousands of cases of unsold low-end wine.
