Her mother Jan Jones had bought the bottle for granddaughter Abi's 18th birthday and they had poured a glass to toast the occasion. Justine Jones was left covered in huge sores and in agony after opening the bottle of Tesco Finest Garnacha wine to celebrate her daughter's birthday . But despite the bottle being sealed and showing no evidence of being tampered with, the family were shocked when they inspected it further and found it contained a clear liquid which smelt of bleach. Mother-of-two Ms Jones, 44, said: 'It tasted foul. I inspected the bottle and found that the liquid was clear and had bits of mucus and bits floating in it. 'My daughters and mum smelt the liquid and thought it had a faint smell of bleach. We were horrified.' Despite the bottle being sealed and showing no evidence of being tampered with, the family were shocked when they inspected it further and found it contained a clear liquid which smelt of bleach . The accountant, from Shropshire, suffers from rare condition pemphigus, which means her immune system is extremely sensitive to certain chemicals and attacks her body leaving serious blisters. The next day she was covered in huge sores and had to be referred to hospital. The bottle, bought from a Tesco branch in Market Weighton, East Yorkshire, was taken back by her mother who demanded it be tested and investigated. She said: 'I felt alarmed, Justine has such a poor immune system we have to be careful really.' A letter from the supermarket giant said a report had been sent to their technologist and that the wine had been provided by a supplier. Tesco wrote: 'The technologist acts as a regulator, and will follow it up with the people who make this product for us, as well as keeping an eye on all incoming complaints.' But Mrs Jones said the response was not good enough. 'I feel awful about their response. They sent me £10 and a £15 moneycard'.

'I wasn't looking for money, I wanted a result. I suspected it was cleaning fluid.' Her daughter added: 'We were incensed. This is particularly worrying as our product had obviously been tampered with and caused me considerable pain.' A Tesco spokesperson said: 'We're sorry we let Mrs Jones down with our investigation. We take all complaints extremely seriously, our team will be looking at what went wrong to ensure it doesn't happen again.'
