The Danish beer giant Carlsberg has had to dispose of around 3m cans of beer due to problems with their contents, the company said today.

"We have discarded 3.3 million cans because the beer stank and tasted sour and was cloudy," Carlsberg Communications manager Staffan Bremander said.

The company said the cost associated with this action was minor. However Carlsberg supply chain director Jette W. Knudsen will leave the company following the problems with the cans, Reuters reported today.

"The reason for her resignation is that over the summer there have been some production problems, especially in relation to the introduction of cans in Denmark," Carlsberg said in a statement.
