My wife and I aren't heavy drinkers. We may only have a glass of wine each on a given night, and sometimes we prefer different wines, so multiple bottles tend to stick around in our fridge several days after opening.

If that sounds like you too, these vacuum-sealing stoppers are handy to have around. They fit over the top of most wine bottles, and a few presses of the top button removes air from within and creates a tight seal, greatly slowing down the oxidation process so your wine stays fresher for longer.

The button also acts as a date marker dial, so you can always remember the exact day you opened that particular bottle ?

There are a bunch of brands selling these on Amazon at different prices, but it's hard to beat this $9 two-pack value-wise.
