Skip the Glass Bottle Stopper and enjoy Wine-by-the-Glass with Coravin
Why a Glass Bottle Stopper is Useless for Wine Preservation
Glass bottle stoppers or simple wine glass bottle tops do just one thing: they close the bottle. That’s helpful for a few hours. But oxidation still happens, carbonation fades and aromas lose shape. A glass bottle stopper can delay the obvious but it can’t protect what most matters in wine: the taste, the bouquet, the bubbles.
If you’re pouring wine-by-the-glass, you need more than a seal. You need control. You need Coravin.
What Coravin does differently
Ever wish you could pour a single glass of wine and not worry about the rest? With Coravin wine by-the-glass systems, you can.
Using a precision-engineered needle, oxygen exposure is controlled instead of leaving preservation to chance. Coravin is perfect for wine lovers and collectors who like to enjoy wine on their own terms.
For restaurants and bar owners, it is the chance to upgrade your wine-by-the-glass service, offer tasting flights and expand your wine menu.
Discover Timeless, Pivot, & Sparkling superiority over glass stoppers
Coravin Systems lets you pour without pulling the cork. Unlike a simple wine stopper that only reseals the bottle, they protect the remaining wine with Pure® Argon gas, keeping its aromas and flavors perfectly fresh, even years later.
These three systems are part of the Coravin wine-by-the-glass system. One unified approach that takes wine enjoyment to the next level.
Timeless™
Timeless is the all-around favorite for wine lovers who equally enjoy vintage rarities and their everyday favorites.
With Timeless you can access a vintage without removing the cork, open that rare bottle you’ve been saving for a special occasion without worrying it will go to waste if not finished.
The precision-engineered needle and advanced materials minimize oxygen exposure.
Pivot+
Pivot is for casual drinkers and restaurants. Fast, reliable pours for every night or every service.
Perfect for tasting flights at great speed. It’s practical, elegant, and made to last.
Sparkling®
Sparkling is meant for sparkling wines.
For celebratory pours or just to indulge on your favorite bubbles on a quiet evening, you can enjoy it knowing you’ll meet preservation in a way no wine glass bottle top or glass stopper can.
Materials & Engineering You Can Trust
Coravin is built to be used every day, on special bottles, and in busy service. The precision-engineered needle is made from medical-grade, corrosion-resistant stainless steel so it's both sharp and gentle on corks.
Durable Construction
External components use durable metals and finishes. All seals that touch wine are food-safe: silicone gaskets and engineered elastomers that hold a tight seal without leaching flavors.
Precision Protection
Our innovative design controls oxygen exposure precisely, protecting aroma and flavor so you can keep the rest fresh.
The result is a unique technology that's resistant enough for restaurant service, refined enough for cellar use, and simple enough for pouring at home.
How Coravin works in three simple steps
LEARNING TO POUR WINE WITH CORAVIN IS EASY AND STRAIGHTFORWARD
Attach or Insert
Secure the system to the bottle (or position on sparkling).
Pour
Wine flows out while the bottle stays sealed. The Coravin system controls oxygen exposure.
Enjoy & Save
Sip now and come back later — the wine stays fresh.
Coravin vs Glass Bottle Stoppers
The “seal and hope” approach of glass stoppers is a short-term fix. Coravin is about preservation.
Quick comparison: Coravin vs glass bottle stoppers
| Feature | Coravin wine by-the-glass system | Glass bottle stoppers / wine glass bottle top |
|---|---|---|
| Preservation of aroma & flavor | Precise control of oxygen exposure — wines stay true for days, weeks, or longer. Consistent preservation for tasting-by-the-glass. |
Simple physical seal only — oxidation continues slowly; freshness drops. Good for short-term, not long-term preservation. |
| Preserve the Bubbles | Coravin Sparkling preserves effervescence far longer using targeted preservation for sparkling wines. | Carbonation fades quickly; not engineered for sparkling or long-term effervescence retention. |
| Materials & durability | Precision-engineered needle, medical-grade stainless steel, food-safe seals and engineered elastomers — built for repeated use and restaurant service. | Fragile glass and variable seals; performance depends on craftsmanship and wear. Seals can degrade over time. |
| Designed for wine by-the-glass | Purpose-built wine by-the-glass system — pour single glasses without removing the cork; predictable results. | Designed to reseal, not to enable tasting-by-the-glass; not suitable for repeated single-glass pours. |
| Predictability & consistency | Consistent, repeatable preservation you can rely on for service or cellar use. | Results vary — often hit-or-miss depending on stopper fit, bottle condition, and seal quality. |
| Best for | Casual drinkers, enthusiasts, collectors, restaurants — anyone who wants to pour now and keep the rest fresh. | Short-term storage between pours; occasional use where long-term preservation isn't required. |
