igation has revealed that wine-lovers may not be getting the deal they think at the tills.Price comparison website mysupermarket.co.uk tracked the prices of big name brands over a year and found that their graphs created a zig-zag pattern which suggests artificial inflation.
According to The Guardian, which commissioned the study, industry insiders claimed that many of the promotions are manufactured.
They said that a £5 bottle that is advertised at half price will never have been worth £10.
Alan Cheeseman, who is a former director wine for Sainsbury's, told the paper: 'Some of the half price offers at the supermarkets are blatantly manufactured.'
He added: 'The problem is that as a nation we have become promotion junkies.'
Mysupermarket's investigation studied all supermarkets in the UK except Morrisons because the prices were taken from stores delivery services.
Waitrose have since claimed that their figures did not match up to the research.
