This article is interesting, it suggests that it is possible to turn young wine into something more pleasant simply by passing an electric current through it. A study was carried out on a three month old Cabernet Sauvignon from a Chinese winery. The batches of wine spent one, three or eight minutes in various electrical fields before being analysed and sampled by a panel of tasters. It was found that the wine which was initially "harsh and pungent" had become "harmonious and dainty" and tests found the chemistry of the wine had changed making it less acidic and more fruity and fragrant. I wonder if there is a way to do this at home?
