TREASURY Wine Estates has again denied it is on the market amid rampant speculation across the industry.

Two Victorian growers who supply TWE have contacted Weekly Times Now in the past week to say they had been informed TWE was up for sale.

A grape grower from Merbein who supplies TWE but would not be named, said she had been told a takeover bid was underway.

Weekly Times Now
has received several anonymous tip-offs, also claiming the winery is up for sale.

One claimed Chinese company Bright Food was set to take over the winery.

Bright Food is a multinational food and beverage manufacturing company headquartered in Shanghai, China, and is rumoured to have had it's eye on the Australian wine market.

TWE is the second-biggest winemaker in the world and heads 54 wine labels including prestige label Penfolds.

Despite speculation, TWE has partnered with the Melbourne Food and Wine Festival, to be held in March.

TWE spokeswoman Rebecca Smith said TWE would not comment on speculation.

"For us its just business as usual,'' Mr Smith said.

"Our focus remains on building the world's most celebrated and successful wine company for our shareholders.''

The company has suffered several profit falls since it spun off from Foster's Group in 2011 and was at odds with shareholders are staff over pay disputes last year.

Disputes over executive pay in October and worker pay in November have seen operations tense for months.
