About The Machine

What is the difference between Eternal Vino and other wine preservation systems?

Eternal Vino is the only device in the world, which prevents wine from oxidation perfectly. 

Also, unlike other wine preservation systems, with Eternal Vino, once you exchange the cork with our special plugs, switching bottles is very easy, and you can use multiple bottles at once. See the comparison list of wine preservation systems here.  

What is Freshkeep Technology?

Freshkeep Technology (TM)  is the patented technology invented in Japan. The technology enables you to exchange the cork with special plugs in a nitrogen environment and wine never comes to contact with any oxygen through entire process.

Is the plug reusable?

No, the plug is not reusable. 

Since we insert the bottle upside down in Eternal Vino, would sediment go into the glass?

We understand your concerns, but our special plug has a filter to capture all wine sediments from getting into the glass! 

Can I use other gas, such as argon gas?

You can use argon gas, however, we would recommend using nitrogen gas.

What kind of equipment do I need to use Eternal Vino?

  • Nitrogen Gas

  • Regulator

  • Hose
