Keep opened wine fresh for more than a month with the Syphon Minimalist Wine Preserver. This handy device makes it easy and simple to enjoy wine whenever you want to. Forget about the time restriction that usually comes with an opened bottle since Syphon preserves wine as you pour. The patent-pending system uses the same preservation methods as wineries, so you don’t have to finish or waste what’s left in the bottle. Likewise, the wine preserver uses argon, which is the same inert gas that wineries use during the bottling process. Argon releases into the bottle when you pour a glass of wine using Syphon, preventing your wine from oxidizing. Syphon fits any wine bottle and comes with two closure sizes to ensure an airtight fit.
