Ontario's liquor control board is advising that some bottles of a 2006 premium red Italian table wine are likely fake.

The LCBO says people who have purchased a 750-ml bottle of 2006 Negrar Amarone Classico should return it in exchange for a 2007 or 2008 bottle or a refund.

Bottles with the number AAA 09439731 are suspected of being counterfeit and not produced by the supplier.

The bottle shape of the counterfeit wine is different from the authentic wine.

George Soleas, the LCBO's vice-president of quality assurance, said in a statement that the proper wine was purchased by the LCBO, but staff have discovered that some bottles returned to stores are different. The wine has been tested and there are no health and safety concerns, the statement said.

"However, both lab and taste tests show the suspected counterfeit products differ in taste profile and chemical makeup from the authentic product."

The LCBO has pulled all bottles of the 2006 off the shelves as a precaution.

The source of the suspicious bottles is being investigated by police.
