It's official – there is no apostrophe in Harveys.

Campaigners are calling for the brewery, based in Cliffe High Street, Lewes, to spell its name consistently across the brand.

Brighton-based Jonathan Cook at the Apostrophe Protection Society has launched a Facebook campaign called ‘Campaign for Harvey(')s Brewery's apostrophe consistency’.

He has posted pictures of pumps at the Poet’s Corner pub in Montgomery Street, Hove, which shows an aberrant apostrophe in Harveys Best Bitter.

He said: “It looks like the proof reader has got it wrong.”

Mr Cook claimed there are examples of other pubs where the spelling of the brand is contradictory.

Another member of the Facebook group said the campaign ought to win the backing of CAMRA – the Campaign for the Right Apostrophe.

Bill Inman, marketing boss at Harveys, said he was not aware of the Facebook campaign and insisted there are no plans to change the spelling of the company name.

He said: “There is no apostrophe in Harveys. If one appears on a pump somewhere it is without official sanction and I want to see the evidence.

“I suppose the technical view is there should be an apostrophe in the name, but I think there is a certain idiosyncratic charm in not having one.

“I don’t have a Facebook account because I like to preserve a modicum of privacy. But if this chap wants to entertain himself and his friends with this campaign I’m delighted for him.”
