When wine is exposed to air, it starts reacting with the oxygen in the air. Because of this "oxidation" the wine starts to lose flavour, aroma and colour. And, usually after a day of two or three, the wine loses so much quality that it becomes unpleasant to drink.

Since oxydation is the problem, removing the oxygen seems like the obvious solution - and it is! With Airtender vacuum wine savers, you pump out air from an opened bottle, sealing it with a Nanostopper stopper. This way, oxidation is slowed down and this will keep your wine fresh up to 5x longer! So, on average, in stead of lasting for 2-3 days, youw ine can stay fresh for weeks.

The science is quite simple, but really effective. That's why millions of people at home and in hospitality choose vacuum savers to serve wine by the glass and keep wine fresh for later.

Vacuum stoppers won't work on sparkling wines for two reasons:

1) The gas that is released from the wine will cancel the vacuum over time
2) The vacuum will cause the gas to be extracted, so the wine will go flat

But keep a close eye on us, because we just might just develop the next-generation solution for sparking wine saving!

The working principle of traditional vacuum wine savers is the same: extract air from a bottle to slow down oxidation.However, the Airtender wine savers were developed to overcome a few important limitations of existing pumps and stoppers.

For cork & screw cap
The Nanostopper is the only vacuum stopper that properly works on bottles with cork and screw cap.

Horizontal storage
The Nanostopper is the first and only vacuum stopper that fits beneath a screw cap. This makes it the only shystem that allows you to store vacuum sealed bottles horizontally

Double vacuum indicators
The Airtender wine saver is the only wine saver that has a vacuum indication on the manual pump and the stopper. So you will always know when to stop pumping and that the bottle is properly vacuum sealed. The Electric Food&Wine Saver will automatically stop when the vacuum level is reached.

Non-toxic
The Nanostoppers have been made from premium silicone, whereas traditional stoppers are made from synthetic rubber.

You can clean them however you prefer: you can hand wash them with dish soap, but the Nanostoppers are also dishwasher safe.

Do make sure to avoid using any abrasive or aggressive chemical cleaning agents.
