We all know the drill; once you open a bottle of wine, you have to drink it.

And while most of the time we won't protest to that, there are times when we only want one glass (or fall asleep two glasses in).

But, once you open the bottle, it won't be long before the wine starts to taste pretty awful.

If you're into your vino, then you'll know that the minute wine mixes with air, it starts to oxidise which changes the taste.

So, now you have three options for that lovely half-bottle of red; begrudgingly drink the foul-tasting vino; throw it out (sob); or use it while cooking (which you won't).

We don't fancy choosing any of those options, so that's where this little gadget comes in.

Say hello to Eto, a patented decanter with an airtight seal which promises to to keep red, white and rosé wine fresh for up to 12 days.

Experts have said that most standard wines will only last two to three days max once opened, so Eto is definitely going to save us wincing every time we take a sup of gross, gone-off wine.

Praise be.
