Cains Brewery has criticised the drinks industry and the British Beer & Pub Association for failing to back its initiative to put warning labels on bottles.
In a letter to The Publican Sudarghara Dusanj, managing director of the Liverpool brewery, said: "We're relative newcomers to the brewery business but have been surprised by the amount of talk, and lack of action, when it comes to addressing industry issues.
"Although we don't claim that our new label advice will solve the problem, we're taking a step in the right direction and doing the responsible thing to prompt our consumers to think about how much they're drinking.
"So it's quite a surprise that the BBPA seem to be lukewarm about our actions, especially considering that we have the full support of the Portman Group."
Mark Hastings, spokesman for the British Beer & Pub Association (BBPA), said: "Cains are entirely free to act in the way they feel is best for their consumers but as an industry our research shows that warning labels have very little impact on consumers drinking habits.
"The whole of the industry recognises it is responsibility in this area of encouraging sensible drinking. Part of that commitment is our close relationship with the government to develop solutions that are truly effective."
