An Australian winemaker has patented a method of removing sulphur dioxide from wine immediately prior to consumption.
The system consists of a levered plastic stopper which is placed on the top of the recently-opened bottle of wine. When the lever is raised and dropped, a small amount of hydrogen peroxide is released. The hydrogen peroxide neutralises the sulphites and the stopper can be removed.
