Ever since the creation of wine and the discovery that oxygen + wine = a less than fresh taste, people have attempted to create wine-preservation gadgets to help keep wine fresh. You can find many on the shelves at stores, but the real question is knowing whether or not they actually work.
A Vacuvin is a pump device that uses suction power to draw the air out of the bottle, which then leaves behind a partial vacuum. While the idea behind it isn’t a bad one, several testers find that it has no real effect in maintaining wine freshness.
The Private Preserve claims that it is the number one wine preserver in the world. You spritz in a bit of nitrogen into a bottle, and because nitrogen is heavier than air, it settles in as a layer over the wine, thus protecting the wine from oxygen. So far, testers are so-so about this gadget.
You can always go completely old school and drop clean glass marbles into a bottle, forcing the wine to the neck, pushing oxygen out completely. Of course, as you reach the end of the bottle, you’ll need a lot of marbles!
