Allied Domecq has raised its offer for Peter Lehmann Wines as it tussles for control of the Aussie winemaker with Swiss group Hess.

Lehmann has backed the bid from Hess after it matched Allied Domecq’s £60m bid. The board believed a takeover by a big multinational could “compromise the company’s independence”.

But Allied has now upped its offer by 15 cents a share to value the winemaker at £62m, on condition that its share in Lehmann is increased from its current 14.53% to at least 50.1%. Previously, AD had wanted that share to be 90%.

Hess - which owns vineyards Stateside in the Napa Valley - was due to buy Lehmann at the beginning of September before AD stepped in.
