Wine screw caps increasingly damaged with bad results for taste

The use of corks can lead to cork taint but new research has found that more than 20 per cent of screw cap wine bottles end up with damaged caps, which can in turn cause chemical changes in wine.
Wine expert Alison Eisermann-Ctercteko says cork taint used to leave a bad taste in the mouth.
“When it’s at high levels, it’s really quite unattractive. So the wine smells like mouldy leather or the back of the cupboard where you find those sort of sports bag and shoes,” she said.
“And the wine won’t have much fruit flavour.”
Ms Eisermann-Ctercteko undertook a self-funded study of screw cap wine bottles across 22 stores in New South Wales, visually inspecting the tops for damage.
“All different sizes, in different suburbs, looking from quite small boutique, very specialist retailers, to large warehouse-type retailers,” she said.
“In total I surveyed over 10,000 wines in Australia, and I did about another 2,000 in the UK.”
