REAL ale is growing in popularity, says a new report.
And brewers in Huddersfield have welcomed the boom.
The report - Real Cask Beer: A Route to Success - has been produced by the Campaign for Real Ale (Camra), Independent Family Brewers of Britain (IFBB) and the Society of Independent Brewers (SIBA).
It was launched this week at the Great British Beer Festival in London.
The report shows that more and more people - particularly those under 25 - are choosing cask beer.
The report also stressed the importance of local breweries in the rise of cask beer's popularity.
Regional and local breweries make up half of cask beer producers.
Also, about 60% of regular pubgoers think it is important to have locally brewed beer in a pub.
Staff at small breweries believe the individuality of their beers is the key to real ale's growing popularity.
John Broadbent, owner of Golcar Brewery in Swallow Lane, said: "The sales of traditional beer have gone up over the three years we have been going.
"I think the attraction is that there's more flavour and the beers are individual."
Andrew Moorhouse and wife Maxine run the Rat and Ratchet pub on Chapel Hill, Huddersfield.
The pub stocks 14 different beers at any one time and rotates 20 different guest ales. Andrew also runs a small brewery on site. He said: "Real ale is a large proportion of our income.
"It's becoming more popular. I think it's because it has flavours that are much more interesting.
"Also, over the past few years, there have been a lot of pale bitters brewed, which appeal to lager drinkers," added Andrew.
"There is a vast difference between what small breweries make and what national companies produce.
"National breweries make one flavour for the masses, small breweries make more flavours. Not everyone might like a particular beer, but pubs change their real ales, so people are bound to find one they like."
Camra welcomed the report, saying it dispelled the common myth that the cask beer market was declining.
Mike Benner, Camra chief executive, said: "A clear message from this report is that real cask beer is not under-performing.
"Consumers are moving towards local food produced naturally, in time-honoured ways. Cask beer fits that bill."
