Lager drinkers are being urged to give mild a try in May by the Campaign for Real Ale (Camra).
Research shows that 65% of alcohol drinkers have never tried real ale, despite the fact it is perceived to be Britain's national drink.
Non real ale drinkers have highlighted the fact that they perceived real ale to be "too bitter".
"This campaigning month is a perfect opportunity for those that have showed an initial interest in real ale but are not sure where to start, or think all real ale is bitter, to try a pint of mild," said Camra's national beer styles co-ordinator Ruth Tyrell.
Camra has supplied hundreds of pubs across Britain with promotional packs that include pump-clip crowners to highlight what milds are on at the bar, plus posters and leaflets to help educate more consumers on the beer style mild.
JD Wetherspoon will have four different milds available in a number of outlets this month.
