In Coravin wine preservation systems, the Coravin screw cap plays a vital role. It is made of self-sealing silicone and helps preserve wine for up to 3 months. This article will discuss everything you need to know about Coravin screw caps and the benefits of using them to protect your wine.

How Does a Coravin Screw Cap Work?

Coravin screw caps

Just as its name suggests, a screw cap is a metal cap that screws onto threads on the neck of a wine bottle. A layer of silicon, rubber, etc., is used to make a seal. The main goal of using a screw is to keep the bottle of your favorite drink safe.

Coravin screw caps are specially designed to keep the wine fresh for longer and give the Coravin wine opener easy access to the bottle.

There are two types of Coravin screw caps. The standard one fits 98% of wine bottles, while the large one fits 2% of wines. Compared to a cork, screw caps reduce the possibility of wine oxidation and cork taint. After removing the actual cork, the screw cap seals the bottle and keeps the wine fresh for 3 months.

Why Should You Use a Coravin Screw Cap?

Coravin screw caps combine self-sealing silicone and the same premium cap liner to create a tight seal that protects wine for longer. With the help of Coravin screw caps, you can enjoy a glass of your favorite wine and preserve the rest for later.

Each screw cap is made with self-sealing silicone that can withstand up to 50 punctures. So if you’re looking for a way to preserve your wine bottle for a more extended period, Coravin screw caps are the perfect solution for you. Remember, not all great wine comes in a corked bottle.

Does Coravin Work With Screw Top Bottles?

One of the most FAQ about the Coravin wine system is whether it supports screw top bottles or not. Technically, it doesn’t, but using a Coravin screw cap can solve this issue. 

Furthermore, the Coravin screw cap installation process is uncomplicated. Just follow these simple steps:

  1. Remove the existing screw cap. Remember not to pour wine from the bottle at this stage.
  2. Then, replace the regular screw cap with the Coravin screw cap.
  3. Now, press the Coravin wine opener’s trigger repeatedly to clear out the system’s existing wine or air.
  4. After that, put the Coravin wine preserver on the newly installed Coravin screw cap.  Gently push it down.
  5. Slightly angle the bottle so that the wine comes to full contact with the screw cap. Press the trigger to pour wine into your glass
  6. When finished, remove the Coravin wine opener and leave the Coravin screw cap to protect your wine from oxidation.  
  7. Finally, you can store your wine bottle. Keep the bottle in the dark place for better results.

Pro Tips:

  • Remove the Coravin screw cap when you have enjoyed the last glass. Clean it with water and dry it using a clean cloth.
  • Replace the Coravin screw cap after 50 pierces.

Yes, of course. Each of the Coravin screw caps can withstand up to 50 punctures. An average glass contains 150 ml of wine. Based on that information, the cap should last for approximately 10 bottles.

Coravin has even conducted blind taste tests with experts on wines under screw caps at 1, 2, and 3 months. The wine experts couldn’t find any difference between the new and used wine bottles with Coravin screw caps.

Which is Best to Use - Cork or Screw Cap?

Corks have been around since the 1400s. It is cheap, environmentally friendly, and aesthetically pleasing. The most significant advantage of cork is also its biggest fault.

The cork is expected to create a tight seal. But technically, that seal isn't airtight. If you look at any cork, you'll see the unique gaps and holes that allow air to pass in and out and touch the wine.

This is where the screw cap comes in. A screw cap seals the bottle completely, which means that the wine cannot oxidize or age. You will get a zero percentage of air touching the wine once it's been screw-capped, so the wine itself won't age quickly.

Now comes the crucial question. Which type of sealing is the best? Well, that depends.

If you like crisp white wines, then you'll want to find a bottle with a screw cap. Screw caps hold the wine’s freshness and crisp quality and help bring the grapes’ punch out. Red wines on screw caps are also great for drinking straight away.

We look for corks when we want something that is a little more mature or want to age. The cork in a wine bottle helps soften the wine’s flavor. Not every bottle does well under aging, but when it does, it pays off immensely.


Hopefully, this post helped you understand the process of using Coravin screw caps. Using a Coravin screw cap is a great option to have when trying to preserve your wine for a long time. It is also easy to use and complements your Coravin wine opener.
