When you've had a long day and want a single glass of wine, not the entire bottle – you shouldn't have to worry whether your open bottle will still taste fresh tomorrow.
Every wine lover knows the frustration: you finally uncork a special red wine or Chardonnay, enjoy one glass, and suddenly the remaining wine begins losing freshness. Oxidation creeps in, flavors dull, and before long that bottle of wine you were excited to drink becomes wasted wine.
You're not alone. Wine enthusiasts everywhere struggle with how to preserve wine effectively at home, especially when juggling multiple bottles or expensive wine bottles they don't want to finish in one night. It's a common question: how much wine can you really save without compromising on quality?
The good news?
Modern wine preservation systems and wine by-the-glass systems are smarter than ever, allowing you to enjoy different wine styles – still wine, sparkling wine, red wine, and white wine – without worrying about spoilage.
These systems help keep wine fresh for days, several weeks or even years later, depending on the technology. Whether you're sipping from one bottle over time, enjoying a half bottle with dinner, serving guests at home, or running a wine bar or restaurant, the right wine preserver system lets you pour wine on your terms.
Before diving into our best wine preservation system tools, here's what you should know.
A) How Long Can You Keep a Bottle of Wine Once Opened?
Once you pop the wine cork, oxygen exposure begins immediately. Oxygen contact is what leads to oxidation – wine's slow fade from bright and flavorful to flat and tired.
Typically:
- Light white wines stay fresh for 3–5 days
- Fuller red wines may last up to a week
- Sparkling wine loses bubbles within hours without a proper stopper
- Older bottles deteriorate faster
Even with recorking or simple wine stoppers, air still seeps into the bottle, affecting both taste and aroma. Storing an open bottle in a wine fridge helps, but isn't enough on its own for serious wine preservation.
To genuinely preserve wine, you need a preservation system that keeps oxygen out, whether through argon gas, vacuum systems, or carbonation maintenance for sparkling wine. This is where modern wine preservers like Coravin wine by-the-glass systems truly shine, transforming everyday routines into something closer to a professional wine keeper at home.
B) What Are Wine Preservers and How do They Work?
A wine preserver slows or stops oxidation after you open the bottle. Depending on the system, you can enjoy a single glass of wine while keeping the freshness and flavor intact for days, weeks, or even 20+ years in the case of Coravin.
There are three primary categories:
1. Vacuum Wine Preservation Systems
Tools like Vacu Vin use a hand pump to remove displaced wine air from the bottle, reducing oxygen exposure. These systems are fairly easy to use, cost-effective, and ideal for short-term preservation (a few days to a week). As an entry-level wine saver, a Vacu Vin-style device can make a big difference versus simply pushing the cork back in.
2. Inert Gas Preservation Systems
Products like Coravin Timeless, Coravin Pivot, and other argon-based solutions work by replacing oxygen with pure argon gas—an inert gas that doesn't interact with wine. The systems use small gas cartridges to deliver controlled pressure. This method is used in high-end restaurants and wine bars because it preserves taste without altering the wine and acts as a highly sophisticated wine preserver system.
3. Sparkling Wine Systems
Sparkling preservation relies on a carbon dioxide refill system to maintain pressure and keep bubbles intact. Champagne and Prosecco need a different approach from still wines to stay fresh and effervescent.
Each wine preservation approach has its purpose, and the best choice depends on how often you drink wine, how much wine you typically pour, and whether you switch between multiple bottles on a regular basis.
Best Wine Preservation Systems
1. Coravin Timeless - Enjoy Wine by-the-Glass on Your Terms
If you want a wine by-the-glass system that truly redefines how you enjoy wine, the Coravin® Timeless™ wine by-the-glass system stands in a league of its own. Unlike vacuum pumps or standard stoppers, Timeless lets you pour wine without pulling the cork, so the rest of the bottle remains as if untouched even years later.
Insert the precision-engineered needle, tip the bottle and pour. Pure® Argon gas, already trusted in the winemaking process, pressurizes the bottle so wine flows out while the remaining wine stays fully protected from oxygen. Every glass tastes newly opened, anytime you return to the bottle.
Timeless is ideal for:
- Older bottles with delicate natural corks
- Special bottles you want to enjoy on your terms
- Wine lovers who prefer a glass at a time
- Restaurants and wine bars offering premium wine by-the-glass
- Anyone who wants the freedom to explore multiple bottles in a single evening
Timeless works with natural corks, and with Coravin Timeless Screw Caps, it can also be used with screwcap bottles.
The system prevents oxygen from ever touching the wine, keeping every bottle fresh, aromatic and ready for your next pour.
Is Timeless right for you?
If you love premium bottles, keep a collection you want to explore at your own pace or enjoy discovering different wines without opening new bottles unnecessarily, Timeless is the ultimate long-term solution.

"Coravin is my favourite wine gadget! It has completely changed the way I drink and enjoy wine… I just adore it! Before I had a Coravin, I was scared to open a 'nice' bottle as I would fear it it would just go to waste.... But now, I can try it and review the wines for my social media and my tastings and then, enjoy them at a much later date! Sometimes you just want a glass of that beautiful wine that you try and save and Coravin allows that! No more waiting around for the perfect opportunity to open it."
Mike Lawton
Verified Coravin Timeless Buyer
"My wife and I enjoy wines both inside and outside the home but appreciate quite different wines which is why I chose to invest in Coravin Timeless 6."
Sissi
Verified Coravin Timeless Buyer from Breuschwickersheim
"No need to wait until there are guests at the table to decide to open a good bottle... With this Coravin system we can choose to pair our meal at any time with a small glass of good wine. Plus, it doesn't push you to drink just because the bottle is open. In short ... it's great!"
2. Vacuum Systems – Vacu Vin
Vacuum systems like Vacu Vin are the classic starter option: simple, inexpensive, and straightforward. Using a small hand pump, these systems pull oxygen from your open bottle and create a partial vacuum.
They're ideal for:
- Still wines you plan to finish within a few days
- Everyday table wine
- Situations where you don't need a long-term preservation system
The downside? Vacuum systems don't eliminate oxygen contact entirely, and displaced wine aromas can still fade over time.
Still, they keep wine drinkable for a few weeks at best and are far better than just pushing the cork back in.
3. Pivot – For the Everyday Sipper
The Coravin Pivot+® wine by-the-glass system is perfect for wine lovers who want easy, everyday enjoyment and the freedom to keep still wines fresh for up to four weeks. Unlike Timeless, you remove the cork and replace it with a Pivot Stopper.
As you pour, Pure® Argon gas flows in to protect the remaining wine from oxygen so every glass tastes just as vibrant as the first.
Pivot pours quickly, works with any closure type and fits seamlessly into the lifestyle of:
- Regular wine drinkers
- Households with different wine preferences
- Restaurants offering a range of wines by-the-glass
- Anyone who wants to enjoy a bottle over several days without worrying about waste
The Pivot system is flexible, approachable and ideal for enjoying still wines on your terms, without sacrificing flavor or freshness.

"In just a few steps you can open a bottle of wine and keep it perfectly preserved for up to 4 weeks. After uncorking the bottle, you just have to insert the Pivot Stopper and then put the Coravin Pivot on the bottle. Then only tilt the bottle and press the button to pour the wine. Saying it is easy, doing it even more!"
George Miliotes, MS
Owner of Wine Bar George at Disney Springs® at Walt Disney World® Resort
"The beautiful thing about Coravin Timeless is that it allows us to leverage discussions with guests and open them up to new experiences. We love the newer Coravin Pivot. Whether we're using it for our most popular wines because of its quick pour abilities, or wines with extra-long corks or vin-lok closure, it is an integral part of our program."
Brett Zimmerman, MS
Owner, Boulder Wine Merchant
"The Coravin Pivot+ is essential for any serious wine drinker. This simple yet innovative creation offers a reasonably priced option to ensure fresh, uncompromising wine for up to a month after opening the bottle. Pivot™ will undoubtedly improve the quality of your wine enjoyment experience. After all, life is too short to drink oxidized wines."
4. Sparkling – Keep the Bubbly Flowing
The Coravin Sparkling System is a dream come true for Champagne and sparkling wine enthusiasts. With this easy-to-use device, your favorite bubbly will remain fresh and fizzy for at least 4 weeks after opening.
To use, remove the original cork or cap and seal the bottle with the specially designed Sparkling Stopper. When you're ready to pour, insert the Sparkling Charger into the Stopper and press the button to release just the right amount of CO2 to maintain perfect carbonation.
The Sparkling Stopper locks securely onto the bottle, so you can store it on its side in your fridge without worrying about leaks. The universal fit works with all standard sparkling wine bottles.
If you've ever hesitated to open a treasured bottle of vintage Champagne or craved a single glass of Prosecco but didn't want to waste the rest, the Coravin Sparkling System is your solution. Savor that celebratory fizz by the glass whenever the mood strikes, or treat yourself to a festive mimosa or Bellini without the pressure to finish the bottle.
Every pour will taste like you just popped the cork.

"Coravin's Sparkling wine system has transformed how we drink sparkling wines. Personal use or business use this is a fantastic product giving you the option to have a single glass of bubbles over 3 weeks, as required. This means on more expensive wines you can enjoy the same bottle on several separate occasions. Coravin sparkling is easy to use and leaves the wine you come back too still outstanding quality. Bravo."
Katie Bracken
Verified Buyer
"The Coravin sparkling system is an absolute must have for any sparkling wine lover. With the Coravin system I've drunk champagne 10 days after opening and I was still as fresh as the first glass, perfect for when you fancy just one glass but do not want to waste the rest of the contents. I also have a friend that always drinks apérol spritz, now I do not have to buy a new Prosecco every time that she visits me. It's an absolute game changer 10/10 from me."
India Donisi
@winespicegirl
"Coravin sparkling has made my daily life extra effervescent. Where I used to be reluctant to open a nice bottle of Champagne because I knew it would never be empty, now I open a bottle every week to toast life, the sun and the achievement of small and big successes. It is wonderful that the quality remains stable and that I can vary between different Champagne houses and cuvées."
Is this the right wine by-the-glass system for you?
The Coravin Sparkling device is the perfect gift for anyone who loves Champagne, Cava, Prosecco or Sparkling Wine.
With the Coravin Sparkling device you can drink your favourite Sparking wine, Champagne, Cava or Prosseco and save what's left in the bottle for up to 4 weeks. Great for nights where you want a little bubbly, or just a splash of sparkling wine in your Summer cocktail.
5. Seal/Blocker – The Quick Fix for Short-Term Sipping
Wine stoppers are a convenient and affordable solution for preserving opened bottles of wine for a day or two. Wine stoppers work by creating an airtight seal, preventing air from entering the bottle and causing the wine to oxidize and spoil.
To use a wine stopper, simply insert it into the neck of the bottle and press down firmly to create an airtight seal. Wine stoppers are typically used for short-term wine storage, as they do not remove air from the bottle and can only slow down the oxidation process.
Types of Wine Stoppers:
-
Cork stoppers
- Traditional and widely used
- Provides tight seal and controlled aging on the open bottle
- Not recommended to reuse after removal due to expansion and deformation
-
Screw caps
- Increasingly popular for immediate consumption
- Convenient and eliminate cork taint risk
-
Synthetic stoppers
- Alternative to natural corks
- Affordable and provide airtight seal
- Don't allow for gradual aging like cork
A stopper such as the Coravin Pivot+ Stoppers work well for both screw cap and synthetic corks.
4. Sparkling wine stoppers:
- Designed for carbonated bottles (Champagne, Prosecco, Cava)
- Plastic or metal cap with pressure-resistant seal
- Retain bubbles and carbonation after opening
- Better than silver spoon method
- Keep bubbles intact for a few days
Is a stopper the right wine preservation tool for you?
Wine stoppers are particularly useful when you want to enjoy a glass or two of wine, but intend to guzzle the rest the following night. They are also useful when you have leftover wine after a party or dinner and want to save it for a day or two later.
By using an upgraded glass bottle stopper such as Coravin Pivot+ Stoppers or our Coravin Sparkling Stopper, to seal the bottle, you can keep the wine fresh and enjoyable for just a few short days.
Final Thoughts: Which Wine Preservation System Will You Choose?
Every wine lover enjoys wine in their own way. If you want the freedom to pour any wine anytime and return to the same bottle even years later, choose Coravin® Timeless.
If you enjoy wine more regularly and want a simple, flexible solution that keeps still wines fresh for up to four weeks, the Pivot® wine by-the-glass system is a perfect fit. For those who love bubbles, Coravin Sparkling® keeps Champagne, Prosecco and all sparkling wines fresh and full of life for at least four weeks.
If you simply want to keep an opened bottle fresh until the next day, a basic stopper can work for short-term use.
Whichever path you choose, you will enjoy more variety, waste less wine and savour every glass exactly as the winemaker intended.
