Bars are to be banned from offering free alcohol to women and free wine and beer tastings will be curbed under a new system of government restrictions to cut public drunkenness.

There will also be rules to limit “happy hour” offers that encourage speed drinking and soft drinks will have to be sold at the same discount during promotions. Wine in restaurants will have to be served in glasses with marked measures.

The proposals, drafted by the Home Office and the Department of Health, seek to transform social attitudes towards drinking by breaking the association between drink and sexual, financial and social success.

A code for the drinks industry, leaked to The Sunday Times, marks a hardening in the government’s stance after the failure of a voluntary code to curb binge drinking. Hospital admissions linked to excess alcohol have more than doubled in the past 10 years.

Threats by the government over the past four years to crack down on irresponsible behaviour by the drinks industry have foundered under the onslaught of aggressive discounting and promotions.

The mandatory code of practice has alarmed the drinks industry with an elaborate series of rules including:

— Cigarette-style health warnings will have to be displayed wherever alcoholic drinks are sold. This would include shops, bars and, according to the industry, could force restaurants to place an official “sensible drinking message” on every table.

— A curb on promotional free wine, whisky and beer tastings. No samples may exceed 125ml and “care must be taken to ensure that customers do not return for further tastings and run the risk of becoming intoxicated”.

— A ban on drinking games, such as downing a glass in one, and “drink all you like” offers for those paying an entry fee will be abolished.

— Wine in restaurants will have to be served in glasses with measures marked on the side.

The government intervention represents a belated acknowledgment that hopes that Britain would adopt a civilised “cafe culture” with the introduction of 24-hour drinking have failed.

It uses disdainful language to describe the attitudes spread by Britain’s bar culture, which it blames for equating heavy drinking with personal success.

It warns that drinks should not be promoted as a means of boosting one’s “social, sexual, physical, mental, financial or sporting performance”.

The practice of selling cocktails called Sex on the Beach, or more sexually graphic names, will also be scrapped.

The safe drinking signs will have to include a statement from chief medical officers about safe daily drinking limits; a graphic showing the number of alcohol units contained within each glass or bottle and the address for a website offering information on drinking moderately.

Casual bar staff may be forced out by the proposed mandatory code, which will require all bar employees to undergo accredited training.

It could become an offence to fail to ensure that staff have been trained in checking a customer’s age, turning away underage customers, refusing to serve customers who have overindulged and preventing drunken disorder.

Alcohol Concern has been calling for staff training in preventing excessive and underage drinking to be a requirement of a pub gaining its licence.

The mandatory code, which would be enforced by Trading Standards, was this weekend welcomed by health experts. Professor Ian Gilmore, president of the Royal College of Physicians, said: “The voluntary partnerships of the drinks industry are clearly not working. Mandatory codes at this stage are essential.

“I think the next step will be to tackle the heavy discounting through a minimum price for a unit of alcohol.”

Mark Hastings, communications director of the British Beer & Pub Association (BBPA), said the proposed rules could prevent students doing bar work during the summer holidays and could make it impossible to recruit enough staff for big sporting events, including the 2012 Olympics.

“Most of these proposals are disproportionate and some are just plain daft. Every restaurant table and hotel room will need to have a detailed sensible drinking sign. Every document published by a drinks company will need to carry the sensible drinking message,” he said.

This weekend The Sunday Times found bars were continuing to flout the voluntary code. At the Envy nightclub in Notting Hill, west London, groups of women were being offered free bottles of wine as part of the Crazy Sexy Cool Party promotion on Friday night
