UK beer maker BrewDog is under fire from industry watchdog Portman Group following a complaint about four of its products.

The alcohol industry body, which was set up to monitor the promotion and advertising of alcohol, claims that four of the company's beers are in potential breach of the official code of practice.

The beers include Punk IPA, Rip Tide, Hop Rocker and Speedball.

It is understood Punk IPA and Rip Tide could be taken off shelves across the country after claims its labels were deemed to be associated with antisocial behaviour.

Hop Rocker, which is marketed as including "nourishing foodstuff", implies the beer can enhance drinkers' mental and physical capabilities, according to the Portman Group.

"We received some complaints about BrewDog and they are being processed through the normal route which is our independent complaints panel who will hear the complaints made against BrewDod," a spokesperson told just-drinks. "The panel will make the final decision."

An online petition, launched against the Portman Group's action, was set up by drinks writer Melissa Cole who has condemned the actions of the industry watchdog as "completely unacceptable".

The hearing is expected to take place in the next few weeks.
