Wine Preserva has developed a unique approach to preserving the quality of the wine from the moment the bottle is opened, to the last glass. The Wine Preserva is a disk system which, when inserted in an opened bottle of wine, keeps the nose and taste of the wine “at restaurant quality” for up to 5 days. The disposable disk is simple and easy to use, and does not contaminate or taint the wine. It provides restaurateurs the ability to reduce waste and increase margins by increasing the range of wine-by-the-glass they offer. Similarly winery cellar doors can confidently keep multiple wine bottles open overnight
