Domaines Barons de Rothschild (Lafite) (DBR) has once more extended its takeover offer of The Chalone Wine Group. It is the second extension of the proposal to acquire all of Chalone's outstanding publicly held shares of common stock at $9.25 per share in cash in a week.

The offer has now been extended to 3 September.

In May, Rothschild, Huneeus Vintners and Constellation Brands announced they were proposing the formation of a new independent joint venture to create what would be one of the world's leading luxury wines companies. The deal included the acquisition of Chalone.

Under the terms of the joint venture, Constellation Brands and Rothschild will provide the cash funding for the purchase of the Chalone shares.

The extension follows an announcement earlier this month that the deadline would be 20 August. The US$9.25 a share offer was initially scheduled to close on 30 June.
