Truly extend the life of your wine. PlatyPreserve is the best way to protect the taste of an opened bottle of wine by completely eliminating the presence of oxygen. While alternative methods might have you pump air out of the bottle or inject gas into the bottle- PlatyPreserve has you transfer your un-finished wine into an air tight reservoir to truly protect the taste of your wine so it may be enjoyed several days or even weeks later.So go ahead, open a bottle or two. With PlatyPreserve, you can open a bottle of wine, if only to enjoy one glass. Or open several different bottles — such as a red and a white — with the flexibility to enjoy them at your leisure.
