If you like wine, but don’t want to finish the entire bottle each time you open it, check out the 3-botle wine saver. I have fiddled around with several different type of caps and corks, but none of them really seem to prolong the life of a bottle of wine once it has been opened. The reason is because the wine comes into contact with oxygen. If you want to prolong the shelf-life of wine, you have to remove the oxygen. That is what the wine saver does. It replaces the dispensed wine with argon, an inert gas that does not interact with the wine.
I found this cool website. Check it out. http://glass-goblets.com/
