Keeps open wine fresh for 2 weeks. I gave this to my in-laws, they love it, since they don't usually finish a bottle at one sitting. Available in most liquor stores, you just have to look for it.

helps keep multiple bottles open at any one time. it's awesome.

Remember- you are only supposed to have one or max two glasses of wine for the anti-oxidant benefits. So don't drink it all at once. Use the Vacu Vin to help keep your wine good so you can savor a bottle over a couple of days. (via auntbeep)

I received this as a stocking stuffer a couple years ago, and I haven't found anything better to keep a bottle of wine fresh. It's nothing fancy, and costs like 5 bucks - but it's one of the best, most functional products I have in my kitchen. (especially for that bottle of white I keep in the fridge for cooking)

It takes me a week to finish a bottle of wine by myself. The vacu-vin keeps it fresh as the day it was opened. (via esh)

I'm not an expert, but this seems to help the wine last a bit longer. It was also recommended to me by a bartender.
