Save 65%: Hack Your Own Coravin Argon Gas Capsules

The Coravin Wine Preservation System is fantastic. It’s an easy way to dispense wine without pulling the cork since the device cleverly replacing the excess volume with argon instead of oxygen (the enemy of wine). You can pour just a glass or two at a time and easily save the rest of the bottle for later.

However, the Coravin Argon Capsules are almost $10 each. And while they claim to pour 15 glasses of wine, they never seem to actually make it that far. As a result, we end up going through a capsule for every 2-3 bottles meaning there’s a “Coravin Tax” of up to $5.00 per bottle. Ouch!

Turns out there’s a cheaper way. While the Coravin Capsules claim to be proprietary, the metal cylinder is just a standard 3.5” food grade argon capsule. The only unique part of the capsule is the plastic cap.

This cap houses a very important rubber o-ring that ensures a good seal between the capsule and the Coravin. So, all we need to do is remove this cap from a used capsule and we can use it with much cheaper non-Coravin capsules!

To do this, grab a pair of channellock pliers for the metal body and a smaller pair of pliers for the cap. Grab the capsule with one set and the tip of the plastic cap with the other. Make sure you have a secure grip on both and turn counter clockwise if you’re facing the top of the capsule. With a little effort, you’ll unstick the glue and at which point you can easily unscrew the cap.

There are plenty of options for 3.5” food grade argon capsule. The cheapest I’ve been able to find are for another, much less effective, wine preservation system called Preservino. These capsules come in either a 4-pack or an 8-pack and in the larger case are only about $3.50 each for a savings of $6.50 per capsule!

Simply slip the cap you removed from the Coravin capsule onto one of the standard capsules. Pop this new capsule in your Coravin and you’re in business!

Slip? The top of my Coravin capsule is threaded so there's no slipping at all.
this is post outdated or did you simply misspeak? Using his hack requires threaded argon capsules.

Thomas said...

No threaded argon capsules needed. The interior diameter of the plastic cap including the threads is the same as the thread-less standard capsules. It requires a little pushing, but the plastic cap fits just fine on the standard capsule as pictured.

kellyJJ said...

Thanks, I will give it a try.

How did it turn out?

Thomas said...

Works great! The capacity of the new capsules its a little less than the Coravin ones, but still a huge cost savings. Haven't bought a Coravin capsule since.

Keith Webster said...

can you purchase the threaded cylinders for the ReServe system and use them? they are threaded

Low-cost iSi argon cartridges can be found here:

WINARO - WineSaver said...

In Europe many take the cartridges from Winaro

or Amazon

Kim said...

Thank you for this post. There is also a company that makes fittings to hook-up the Coravin to an argon tank. Check out if you have a minute.

I just bought an adaptator aand tubing from them for my restaurant in France and I will let you know the outcome of it.

Hello Guy,

Can you please comment on how this worked out? Does it work as advertised?

Le Bistrot du Broc said...

I bought the adaptator from bottlethief in California and received after 5 days. Took me 2 minutes to mount it on the Coravin then plus in the hose onto a 2.2kg disposable Argon can.
It works tremendously well and it's saving a lot of money!

Hi Guy,

my problem is the correct misure to the adjust the system for the pression? Do you know the correct way?

Hi Tommy,

Have U check the " zzysh wine cartridge " out? I am planning to use these as alternative since the bottle also threaded. Would U please post a close up photo of the spend Coravin. I want to make a comparision of the threads. I am a new user, haven't got a spend cartridge. THX.

marknivenczy said...

Thanks, Tommy.

I had a feeling that you could just swap the plastic top onto a generic cartidge.

Looks like $5 per generic cartridge is the going rate.

MorningWino said...

Hello Mark

Wondering where you found cartridges for $5?

Also, has anyone tried using CO2? Much cheaper and seemingly should work but I haven't tried as yet.


Lucas Holub said...

You can't use CO2, it will dissolve into solution and make sparkling wine under pressure...

sage533 said...

xxysh cartridges are too short. However if you put a pad on the cartridge they work fine. Thye are 30% smaller than coravin cartridge.

Lo Prige said...

You can Use wikeeps threaded capsules..they fit perfectly once the adaptor is on. Plus the best mix ever for the wine: 79% Argon / 21% CO2... with the same quantity of Gas..made by Linde gas in Europe
They ship all over the world for affordable price.
