I'm so famous there are products named after me. https://www.indiegogo.com/projects/wine-squirrel-preserve-opened-wine-for-weeks#/
Ok that is one of the most elegant solutions to this problem I have seen. Better then the balloon in a bottle!
If you've never had a need for said product because the bottle is always emptied, do you have a drinking problem? Asking for a friend.....
This looks good, I hope it DOES work as I have had disappointing experiences with other preservation products.
You are everywhere... I was at a local store with my wife (she was looking for misc items to decorate the house) and I noticed this guy. Sad for me to think of a character on OF while shopping with the wife, sadder that I had to get evidence (pic or it didn't happen), and saddest as I just have to post... Not wine related, but loosely linked to OP's point ("Squirrel!!")
The only one I have found that really works injects nitrogen into the bottle. Then again, who has wine left over?
