Anyone who’s popped open a bottle of sparkling wine only to find it lost its fizz too quickly knows the frustration—this is precisely why the Coravin Sparkling wine preservation system was created. Here, we’ll break down how this method works, how long you can realistically expect those delightful bubbles to last (we’re talking weeks of preservation!), and whether pairing sparkling stoppers with CO₂ capsules gives you the best value for home tastings or professional service.
How Coravin preserves sparkling wine
The Coravin Sparkling system uses a specialized charger to replenish pressure in your bottle after each pour. This clever approach minimizes oxygen exposure while maintaining the perfect pressure to keep bubbles lively and flavors crisp. The result? Your sparkling wine stays fresh and vibrant glass after glass.
Does Coravin keep sparkling wine bubbly?
When used properly, this preservation system can maintain your wine’s effervescence for days—sometimes even weeks. The charger works by injecting pure CO₂, recreating the protective gas layer that keeps bubbles intact and preserves those delightful aromas and flavors.
Results do vary though: typically, fuller bottles of Champagne or high-pressure styles retain their fizz longer than lighter Proseccos or nearly empty bottles. Many users enjoy perfectly crisp bubbles for about a week, though lab tests show preservation can last up to four weeks under ideal conditions.
Sparkling wine stopper and charger basics
The system includes two key components: a universal stopper that fits most sparkling wine bottles and a handheld charger that uses disposable CO₂ capsules. The stopper creates an airtight seal when clipped on, while the charger safely injects just the right amount of gas—never over-pressurizing your precious bubbly.
Here’s how it works in practice: simply vent the sparkling stopper when ready to serve, pour your wine, then immediately reseal and repressurize. This simple routine works equally well for casual home tastings or busy bars serving Champagne by the glass.
Realistic preservation time for sparkling wine
While some claims suggest up to four weeks of preservation, most users find the sweet spot is about 7-10 days of perfect fizz. Several factors affect how long your bubbles last: how full the bottle is, storage temperature, the wine’s style, and how often you open it.
An interesting tip: you’ll typically notice the loss of bubbles before any flavor degradation. Try pouring a reference glass when first opening, then compare subsequent servings. If that signature lively mouthfeel and fresh taste remain, your preservation system is doing its job perfectly!
Inside Coravin and Bubbl sparkling…
At Wikeeps, we’ve developed an efficient sparkling wine preservation system that combines scientific precision with practical hospitality needs. The Bubbl solution offers both reliable mechanics and a specially formulated gas blend, creating a mobile option perfect for wine professionals and enthusiasts alike.
This portable system maintains your wine’s taste and bubbles without needing electricity – perfect for everything from wine tastings to outdoor events to catering services.
Why add nitrogen with carbon dioxide
Most standard CO₂ systems ignore the danger of oxidation, which is why our Coravin Sparkling capsules use an 80/20 mix of carbon dioxide and nitrogen. The CO₂ keeps the pressure stable and preserves the effervescence, while nitrogen creates a protective barrier against oxygen to safeguard delicate flavors.
- Superior preservation: This dual-gas combination maintains pressure while preventing oxidation, keeping wine fresh much longer than single-gas alternatives.
- Premium quality: We source our gases from Linde, ensuring they’re odorless and tasteless – just like top Champagne producers use.
- Excellent value: A single 27ml capsule preserves approximately seven standard 750ml bottles, while a 600ml refill can handle about 150 bottles.
By replicating both the bottle’s pressure and creating an oxygen-free environment, this system lets you serve multiple glasses over several days while keeping the wine fresh and bubbly.
Smart cap pressure and safe handling
The Smart Cap stopper features a built-in regulator that automatically maintains ideal pressure (2.5-3 bar) for most sparkling wines. After closing the bottle, a quick five-second gas injection restores pressure – any excess safely vents out, eliminating guesswork and preventing dangerous pressure buildup.
Since it’s completely portable and doesn’t need electricity, hoses or heavy equipment, professionals can use it anywhere – from trade shows to outdoor events to temporary pop-up locations.
Service workflow for sparkling wine bars
Simply open your bottle, pour the required glasses, then secure the Smart Cap tightly. Connect the Coravin Sparkling device, hold for five seconds, and the gas mixture will both compress the remaining CO₂ and remove oxygen.
For subsequent pours: detach the device, serve your wine, give another quick gas injection, then store the bottle upright in a 6-8°C cooler to minimize further CO₂ loss.
| Use case | Typical preservation window | Key best practices |
| Home tasting | Up to 7 days | Chill rapidly, store upright, top up pressure after each pour |
| Wine bar by-the-glass | About 1 week | Keep bottles in 6-8°C ice, avoid heat, use large canisters for high volume |
| Multi-day trade fair | Several days | Use portable Tower system with multiple stoppers and a single mobile device for flexible service |
Both laboratory tests and real-world use confirm that aromas, pressure and bubbles stay fresh for about a week, with carbonation typically being what degrades first. Champagne and Cava usually last longer than Prosecco, so always taste test before serving.

Is Coravin Sparkling Wine Worth It?
Whether the Coravin Sparkling system is worth the investment depends on your sparkling wine habits. If you frequently open Champagne or sparkling wine bottles but don’t finish them in one sitting, this preservation system can be a game-changer. Wine professionals and enthusiasts who serve wine by the glass often find the system pays for itself quickly by reducing waste and allowing premium pours without committing to finishing an entire bottle.
Who Should Buy the Sparkling Wine System
The Coravin Sparkling system is ideal if you regularly enjoy Champagne, Prosecco, or other bubbly wines over multiple days. Many positive Coravin Sparkling reviews from industry professionals highlight how it maintains pressure and quality when serving single glasses from the same bottle across different occasions.
However, if you typically finish a bottle in one sitting or only open sparkling wine occasionally, the initial cost and ongoing capsule expenses might not make sense. The system truly shines when used consistently—once users establish a capsule refill routine, the benefits become clear.
- Wine bars and restaurants: High-volume establishments serving by-the-glass programs benefit from 600ml gas canisters, reducing per-bottle costs and streamlining service.
- Wine tourism and trade fairs: The portable setup allows for multi-day events without needing electricity, perfect for roaming tasting experiences.
- Home enthusiasts: Frequent entertainers or collectors who savor premium bubbly over several evenings appreciate keeping bottles fresh without rushing.
- Not ideal for casual drinkers: Those who rarely open sparkling wine may prefer simple mechanical stoppers or smaller bottle sizes.
When evaluating a sparkling wine system, consider both the upfront cost and ongoing capsule expenses. For professional settings, the ability to serve high-margin Champagne by the glass while minimizing waste typically justifies the investment.
Cheaper Alternatives for Sparkling Wine
If a full Coravin or Bubbl. setup feels too expensive, several budget-friendly options can extend your sparkling wine for short-term storage. Quality clamp-style stoppers that maintain pressure can preserve fizz and flavor for 1-2 days, especially when refrigerated.
Opting for smaller formats—like splits (187ml), half bottles (375ml), or even a magnum bottle for parties—helps match quantity to consumption and reduce leftovers. Transferring leftover wine to a smaller container with minimal air can also help, though pouring it may reduce some carbonation.
- Mechanical pressure stoppers: Affordable clamp designs preserve natural pressure for 24-48 hours without any consumables.
- Smaller bottle formats: Buying splits or halves minimizes waste by aligning serving size with your needs.
- Transfer to smaller containers: Moving leftovers to a properly sized vessel can slow oxidation but may slightly reduce bubbles.
Each alternative has trade-offs: cheaper stoppers only work short-term, smaller bottles cost more per serving, and pouring residual wine risks losing some flavor. For frequent use—whether at home or in a wine program—a gas-based Coravin Sparkling wine system provides the most reliable preservation with minimal hassle.
Common Issues with Sparkling Wine Storage
Even the best preservation tools can’t compensate for poor handling. Leaving a resealed bottle at room temperature speeds up CO₂ loss and oxidation, no matter how much gas you inject—so always refrigerate immediately.
How to use Coravin for sparkling wine
Following the right technique ensures perfectly preserved bubbly and extends the life of your opened bottle. Whether you’re using the Coravin sparkling system with pure sparkling CO₂ capsules or our Bubbl. oenological blend, the process stays the same: open, pour, seal tightly with the stopper, recharge with CO₂, and keep chilled until your next serving.
Simple steps for sparkling wine preservation
For best results, always refer to the official Coravin sparkling how-to-use guide to avoid wasting gas or losing carbonation. Perfect results come down to two key factors: positioning the stopper correctly and aligning the sparkling charger properly – these make the difference between average and outstanding, fresh bar-quality pours.
- Pouring your wine: Carefully remove the foil and wire cage, then gently twist the cork out at an angle before pouring each glass smoothly.
- Sealing it tight: Place the universal sparkling stopper over the bottle neck, press down firmly until it sits flush, then lock the handle to create a perfect seal.
- Recharging: Align the sparkling charger straight over the stopper, press and hold until the indicator turns green – this confirms proper CO₂ injection and ideal internal pressure.
When serving later pours, briefly release pressure by tilting the bottle slightly or lifting the handle, pour your wine, then promptly reseal and recharge. This routine minimizes oxygen contact, keeping every glass as crisp and fresh as when you first opened the bottle.
Storage, safety and capsule care for sparkling wine
Store opened bottles upright in the fridge between 6-8°C (43-46°F) to maintain stopper effectiveness and prevent pressure changes. Avoid direct sunlight which can cause CO₂ loss and affect flavor. The upright position also makes serving easier and maintains a better seal with sparkling stoppers.
- Keep it cool: Maintain that 6-8°C temperature between servings – many professional bars use temperature-controlled systems for consistency.
- Smart capsule use: A single pure sparkling CO₂ capsule can typically preserve seven standard 750ml bottles before needing replacement.
- Handle with care: Remember capsules are pressurized – never expose to heat, try to puncture them, or attempt refilling outside the proper system.
When a capsule is empty, pull the lever one last time to release any remaining pressure, unscrew the holder, and recycle the metal shell. Following these steps ensures smooth CO₂ flow, consistent pressure, and reliable wine preservation every time.
Where to get sparkling wine consumables

Frequently Asked Questions
Does Coravin Sparkling work for all types of sparkling wine?
The Coravin Sparkling preservation system is designed to work with standard-sized bottles, from half bottles up to magnums. It’s compatible with various styles of sparkling wines like Champagne, Cava, Prosecco, and sparkling rosés. While all wines will maintain their effervescence initially, you’ll notice that fuller bottles of high-pressure Champagne tend to keep their bubbles and fresh taste longer than low-pressure options like Prosecco. For best results, we recommend taking a small initial pour to test how well the preserved bottle maintains its quality over time.
How long can I realistically keep a preserved bottle of sparkling wine fresh?
When using the Coravin Sparkling system and storing your wine properly refrigerated, most enthusiasts find their sparkling stays fresh and crisp for about 7-10 days. Laboratory tests by Coravin indicate preservation can last up to four weeks. However, actual duration depends on several factors: how full the bottle is, storage temperature, the type of wine, how often you pour, and when the effervescence naturally diminishes—which typically happens before oxidation becomes noticeable.
Are there cheaper alternatives if I only occasionally open sparkling wine?
For those who enjoy sparkling wine infrequently, there are more affordable options than the Coravin system. A good quality stopper that maintains pressure, combined with refrigeration, can keep your bubbles and taste enjoyable for 1-2 days. Alternatively, consider purchasing smaller bottles or transferring leftover wine into appropriately sized containers to minimize air exposure. These budget-friendly alternatives sacrifice long-term preservation capabilities but can be perfect for occasional drinkers.
