A supermarket is investigating a woman's claim that she found a frog in a bottle of wine.Isolde Beesley, complained the creature fell out as she poured a glass of Moscatel de Valencia at a family celebration.She claims she has suffered stomach pains since drinking some of the white Spanish dessert wine, having initially failed to see the amphibian in the bottom of the bottle.Miss Beesley, from Leicestershire, said she had bought the £3.58 bottle from a branch of Asda last December and opened it on Boxing Day.She told Decanter magazine she had since passed the bottle on to her local trading standards office and complained to the company prompting it to temporarily take the wine off the shelves.She has also hired a solicitor and is attempting to bring legal action against the company, accusing it of selling produce which is unfit for human consumption.A spokeswoman for Asda said investigations had found no problems with the bottling process or pests present at the factory."We are at a total loss as to how this could have happened," a spokeswoman said."It's nigh on impossible for any object to find its way into a bottle of wine when it is being produced."It simply can't happen. So somewhere along the line between it being bottled in Spain, opened and being drunk, our unwanted guest has found its way into her glass."Source: orange news
