What is the best way to seal a 700ml wine bottle after opening?
As a supplier of 700ml wine bottles, I've witnessed firsthand the importance of proper wine storage and preservation. Once a bottle of wine is opened, it begins to interact with oxygen, a process that can significantly alter its flavor, aroma, and overall quality. In this blog post, I'll share some of the best methods to seal a 700ml wine bottle after opening, ensuring that your wine stays fresh and delicious for as long as possible.
1. Re - corking
The most straightforward method of sealing an opened 700ml wine bottle is to re - cork it. If you've kept the original cork in good condition, simply insert it back into the bottle. Make sure to push it in firmly but gently to create an airtight seal. However, over time, natural corks can dry out and lose their elasticity, allowing air to seep in. Synthetic corks, on the other hand, are more resistant to drying and can provide a better seal for a longer period.
When re - corking, it's important to note that the wine should be stored upright if you're using a synthetic or screw - cap cork. This is because these types of closures don't rely on the wine to keep the cork moist, as natural corks do. If you're using a natural cork, storing the bottle on its side can help keep the cork wet, preventing it from shrinking and allowing air to enter.
2. Using a Wine Stopper
Wine stoppers are a popular alternative to re - corking. They come in a variety of materials, including rubber, silicone, and glass. Rubber and silicone stoppers are flexible and can create a tight seal in the neck of the bottle. They are also easy to insert and remove, making them a convenient option for everyday use.
Glass stoppers, on the other hand, are more elegant and can add a touch of sophistication to your wine storage. They often come with a decorative design and can be a great addition to your wine collection. Some glass stoppers are also designed to be airtight, using a vacuum - seal system to keep oxygen out.
To use a wine stopper, simply insert it into the bottle's neck and press down firmly. Make sure the stopper fits snugly to prevent air from getting in. You can find wine stoppers in most kitchenware stores or online, and they are relatively inexpensive.
3. Vacuum Sealers
Vacuum sealers are an effective way to remove oxygen from an opened wine bottle. These devices work by sucking the air out of the bottle, creating a vacuum that helps preserve the wine. There are two main types of vacuum sealers: manual and electric.
Manual vacuum sealers are typically more affordable and easier to use. They usually come with a rubber stopper and a hand - pump. To use a manual vacuum sealer, insert the rubber stopper into the bottle and use the hand - pump to remove the air. You'll feel the bottle slightly compress as the air is removed.
Electric vacuum sealers are more powerful and can remove air more quickly. They are often more expensive but can be a good investment if you frequently open and store wine. Some electric vacuum sealers also come with additional features, such as a built - in wine preserver that can inject an inert gas into the bottle to further protect the wine.
4. Inert Gas Systems
Inert gas systems are another option for sealing an opened 700ml wine bottle. These systems work by replacing the oxygen in the bottle with an inert gas, such as argon or nitrogen. Inert gases are heavier than oxygen and will sink to the bottom of the bottle, displacing the oxygen and creating a protective layer over the wine.
To use an inert gas system, you'll need a canister of the gas and a dispensing device. Simply insert the dispensing device into the bottle and release a small amount of gas. The gas will fill the headspace of the bottle, preventing oxygen from coming into contact with the wine.
Inert gas systems are very effective at preserving wine, but they can be a bit more expensive and less convenient than other methods. However, if you're a serious wine collector or someone who wants to keep their opened wine fresh for an extended period, an inert gas system may be worth the investment.
5. Transferring to a Smaller Container
If you don't plan to finish the 700ml wine bottle anytime soon, transferring the remaining wine to a smaller container can be a great way to reduce the amount of oxygen in contact with the wine. A smaller container will have less headspace, which means less oxygen can interact with the wine.
You can use a small glass bottle or a wine carafe for this purpose. Make sure the container is clean and dry before transferring the wine. Pour the wine carefully to avoid splashing or aerating it too much. Once the wine is in the smaller container, seal it tightly with a cork or a stopper.
It's important to note that when transferring wine, you should try to do it as quickly as possible to minimize the wine's exposure to air. Also, make sure to store the smaller container in a cool, dark place to further preserve the wine.
The Importance of Proper Sealing
Properly sealing a 700ml wine bottle after opening is crucial for maintaining its quality. Oxygen is the enemy of wine, as it can cause oxidation, which leads to a loss of flavor, aroma, and color. Oxidized wine can taste flat, dull, and sometimes even have a vinegar - like taste.
By using one of the methods mentioned above, you can slow down the oxidation process and keep your wine fresh for longer. Red wines generally last a bit longer than white wines after opening, but both can benefit from proper sealing.
Choosing the Right Method for You
The best method to seal a 700ml wine bottle after opening depends on your needs and preferences. If you're looking for a simple and inexpensive solution, re - corking or using a basic wine stopper may be sufficient. However, if you want to keep your wine fresh for a longer period, or if you're a wine enthusiast who values the quality of your wine, a vacuum sealer, inert gas system, or transferring to a smaller container may be a better choice.
