Calabria Family Wines and the Medich Family Office have sealed their $50 million takeover and carve-up of the 144-year-old McWilliam’s Wines business after seeing off a late challenge from rival winemaker De Bortoli.

A note to creditors from administrator KPMG said settlement of Calabria’s land sale agreement for the renowned Hanwood Estate and business near Griffith in the NSW Riverina had occurred on May 25, while settlement of the Mount Pleasant business, including the winery and vineyards in Pokolbin in the Hunter Valley, to Medich had occurred on May 21.
