Preservino Gas Cartridges 5 "Wine Preserved!" Jennifer 17 January 2009 What a fabulous thing it really works! On a wine tasting holiday we saw a commercial version using a full sized gas bottle, and wished that there was a similar domestic sized version and lo and behold there it was in Lakeland. Wine stores perfectly, we have been amazed the quality is preserved for up to 2 weeks, we have not tried longer!!
