Molson Coors has teamed up with HM Revenue and Customs (HMRC) to combat alcohol duty fraud.
The brewery has written to its customers asking that any evidence or suspicions of duty fraud, such as emails or flyers offering products at cut prices, are forwarded to the HMRC.
Under the alcohol duty fraud strategy, HMRC will look at supply chains at risk of fraud with producers and agree a range of measures that will cut off the supply to fraudsters at source.
Wholesalers have said that at Christmas time beer sales of certain brands have been 25% lower than they should have been as a result of fraud.
"As a global family brewer we take our responsibilities to HMRC very seriously and as a result have developed a communication channel to feed in any information surrounding suspected duty fraud, which we will use to communicate to all our customers," said sales director at Molson Coors John Heynen.
Anyone suspecting duty fraud can contact HMRC at email@example.com" target="_self">firstname.lastname@example.org or call 0800 595 000.
