If you don't have The Keeper wine preservation system, you're in luck--it's on sale too.  The Keeper is a wine preservation system that allows you to keep a bottle of wine fresh even after it's been opened.  Wine preservation systems allow you to open a bottle of wine without worrying whether you're in the mood to finish the whole thing.

The Keeper is a particularly elegant solution to this problem.  This system isn't bulky and won't take up a ton of space in your kitchen.  Just open a bottle of wine, plug in the stopper and the nitrogen, and you're good to go.  The system replaces the oxygen in the top of the bottle with nitrogen, which is non-reactive and won't change the taste of your wine like oxygen does.  It makes a great gift too!  You can get the standard preservation system, or even one that comes with an extra canister and stopper, allowing you to preserve more than one bottle at a time.
