The company that distributes Buckfast tonic wine is to launch a legal battle against Glasgow City Council because they claim it is discriminating against its product.
Buckfast's distributors, J Chandler & Co, say that some shops have been instructed by Scotland's largest licensing authority not to stock the drink.
Judges at the Court of Session in Edinburgh will decide in October whether there are grounds to judicially review Glasgow Licensing Board's stance.
Although the grounds of any judicial review will not be made public until the case calls to open court, it is understood that Chandler has taken action against the city's licensing authority because of allusions at meetings to "the product which dare not speak its name" - understood to be a reference to Buckfast - and allegations that some retailers were required not to stock it.
J Chandler & Co, which distributes the tonic wine on behalf of Buckfast Abbey in Devon, is also believed to be demanding that no retailer will be asked to provide undertakings not to sell Buckfast in order to secure a licence.
Chandler & Co would not comment, but an industry source said: "There's a feeling that Glasgow will not be the only agency in the public courts.
"Chandler is spending a lot of time and money on this and are fed up getting the blame for society's ills."
A spokesman for the city's licensing board said: "We will defend this action vigorously."
Former Labour justice minister Cathy Jamieson was threatened with a lawsuit by J Chandler and Co over her public call in 2005 for shops to stop selling Buckfast.
The firm said she had broken the licensing act which states no one can ban or influence the sale of a particular product.
