J D Wetherspoon chairman Sir Tim Martin has said that Dry January is turning into a “minor cult” as pub operators prepare for a slowdown this month.

Speaking to City A.M., the recently knighted businessman said people have “always overindulged at Christmas and then tried to compensate in January.

“To an extent Dry January has just given a name to what happened anyway. But perhaps it is turning into a minor cult, even so,” he added.

“Overall, I’m not sure that pubs can legitimately advise people to start drinking in January if they don’t want to.”

Pub operators have previously raised concerns that the campaign, created by charity Alcohol Change, could hinder trade during a quiet period for the sector.

However, Martin said Wetherspoon’s biggest draught brand is Pepsi, with sales surpassed by coffee, while food comprises 40% of its trade days.

Kate Nicholls, CEO of UK Hospitality, said the trade body would “encourage” people to support their local hospitality businesses this January.

She said: “January is typically a quieter time for hospitality businesses and the sector will be hoping for a continuation of the positive sales that were seen across the UK over the Christmas period.

“Hospitality venues pride themselves on being able to offer experiences for everyone, including offering a wide variety of low- and no-alcohol options.

She added: “Pubs, bars and restaurants form a key part of local communities and I’d encourage people to support their local hospitality businesses this January.”
