Yessiree bob! Your own FREE WINE PRESERVATION KIT right here!
No kidding. After all these years, these empty (and resealable) glass bottles are the best way I've found to preserve wine. Ideally, you want to fill them to the brim before sealing, and I recommend you slap a quick label on, so you know what you've got in the fridge.
The glass, resealable 10oz. club soda bottles are particularly helpful (we'll probably see a spike in sales at Wegman's:), but I've used all manner, including empty Orangina bottles. I also get the empty green bottles with corks at places like Sur la Table, but I'd bet they're somewhere on amazon (what ISN'T available there).
These will keep your wine fresh (in the fridge for a week or so), and beat anything else, including expensive "inert gas" kits and Vacu-Vins (which pull out more than just oxygen). Just fill 'em to the brim and seal them up.
Best of all, they're free to use over and over.
