Why screwtops may not be such a corking way to keep red wine fine

The Times, Britain

By Valerie Elliott, Consumer Editor

They thought that the problem of corked wine had been solved by introducing the screwtop. But now red wine producers are grappling with an even worse issue: the whiff of rotten eggs.
Experts believe that one in 50 screwtop bottles — or 200,000 bottles worldwide — may be affected by a chemical process known as sulphidisation. When the metal cap is removed, the consumer is hit with a smell of sulphur — likened by some to burning rubber, spent matches or even a schoolboy stink bomb.
Shoppers are being advised to take extra care when choosing their wine, especially if it is to be laid down in a cellar.
