A new survey has revealed that punters will leave pubs that don't stock classic real ale.
John Smith's commissioned a survey of the nation's publicans and their punters to reveal the staples of the great British local which drive significant value.
Most valued by publicans was a decent pint. However, a television, pool table, and bar snacks also scored highly.
For consumers, friendly bar staff, good food and a large beer garden were the key elements making up their perfect pub.
Of the 229 landlords surveyed, 67 per cent were current John Smith's stockists, with 87 per cent having stocked it for three years or more.
Richard Barnes, marketing manager for John Smith's at Heineken said: "Much like the Great British local, John Smith's holds a special place in the hearts of British pub goers.
"Classic keg ale has a hugely loyal base of drinkers who will leave an outlet if they can't find their regular pint of John Smith's on the bar, which our research shows equates to a significant £25k a year in sales lost per week.
"Similar to the classic pub staples revealed in our survey - the television, pool table and bar snacks - John Smith's remains one of the staples of the Great British local that help increase dwell time and encourage repeat purchase."
