Vacuum cork for wine Xiaomi: how to open, use and not spoil the drink

Xiaomi's vacuum plugs have become a popular gadget among wine lovers, promising to preserve the taste and aroma of the drink for days or weeks, but many users are faced with the problem of how to open this very cork without damaging it and spilling wine? Unlike classic cork or screw corks, vacuum systems require a special approach.

In this article, we will break down all Xiaomi’s vacuum plug models (including the Mi Smart Wine Bottle Stopper and Yeelight Wine Preserver), explain how to open, install and store them correctly, and uncover the typical bugs that spoil both cork and wine. If you just bought this device or have been using it for a long time but are not sure about your actions, here you will find the answers to all the questions.

Spoiler: The process is easier than it sounds, but there are nuances that are not written in the manual, such as why cork can suck too much or how to avoid oxidation of wine when reopened.

What kind of wine bottles does Xiaomi produce?

Xiaomi and its ecosystem (Mijia, Yeelight, Viomi) have produced several models of vacuum plugs, which differ in design, material and additional features, but the principle of operation is the same for all – creating a sealed vacuum inside the bottle.

Here are the main models that can be found on sale:

• 🔹 Mi Smart Wine Bottle Stopper is a classic model with a silicone seal and metal body. Suitable for bottles with a neck diameter of 18-22 mm.
• 🔹 Yeelight Wine Preserver is a smart cork with a pressure sensor and backlight. synced with the Mi Home app to track the state of wine.
• 🔹 The Mijia Mini Wine Stopper is a compact version without electronics, but with an improved vacuum pump. Often comes with a tasting kit.
• 🔹 Viomi Vacuum Wine Stopper - premium model with stainless body and the ability to adjust the vacuum force.

All corks are compatible with standard wine bottles, but check the diameter of your bottle neck before buying - some models may not fit into bottles with a non-standard size (for example, for champagne or fortified wines).

Preparing the cork for the first use

Before opening a bottle with a vacuum plug, it must be properly prepared for operation, a step that is often missed, causing the cork to hold the vacuum poorly or quickly fails.

Here's what we need to do:

1. Unpack and inspect the cork. Make sure that all the parts are in place: silicone seal, metal or plastic housing, pump (if it is removable), some models (for example, Yeelight) have a protective film on the sensor, you need to remove it.
2. Rinse the seal. Wash the silicone part of the cork with warm water and soap and dry it, which will remove the factory lubricant and dust that can spoil the taste of the wine.
3. Check the tightness. Put the cork on an empty bottle and create a vacuum (how to do this, read below). If the cork is tight and doesn't let air through, it's okay.

If the cork is new, but it doesn't create a vacuum, there's probably a problem with the sealer, so try moistening it with water, it'll improve the adhesion to the glass, and if that doesn't work, check if the silicone is cracked or deformed.

💡

Do not use aggressive detergents to clean the cork - they can damage the silicone and leave an aftertaste in the wine.

Step-by-step: how to open the vacuum jam Xiaomi

Now, the key is how to open a vacuum plug bottle properly without damaging it or spilling wine, and it depends on the type of cork, but the overall pattern is the same for all models.

Here's the universal algorithm:

Let's take each step in more detail:

1. Vacuum reset. Most Xiaomi traffic jams have a special button or pressure relief lever. For example, on the Mi Smart Wine Bottle Stopper, this is a small black button on the side of the body. Press it once and you hear a slight hiss (this air goes into the bottle). On the Yeelight model, the reset occurs automatically when you press the top of the cork.
2. Removing the plug. After the vacuum is removed, gently pull the plug upwards. Don't twist it or pull it sideways, it can damage the sealer. If the plug is too attached, repeat the vacuum discharge or slightly twist it from side to side.
3. Check the seal. After extraction, inspect the silicone part. If there are traces of wine or deformity on it, wash it before the next use.

If the cork doesn't open even after a few attempts, don't put too much effort into it, and it may be the wrong installation (read more about this in the next section) or the wear of the seal.

Typical Opening Mistakes – and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakage of the cork or wine, and the most common of them are:

Another common problem is that the cork sticks back after the vacuum is released, and this happens when the sealer is too tightly attached to the bottle neck, in which case you can slightly moisten the edge of the neck with water or wine alcohol, which will reduce friction.

Also, remember that vacuum plugs don't last forever: Silicone seal wears out after about 50 to 100 uses (depending on the model), if the cork gets worse to keep the vacuum or the sealer has cracks, it's time to replace it.

💡

Never use a vacuum plug for soda bottles (champagne, beer, soda) and the pressure inside can damage the cork or even break the bottle!

How to install the plug correctly - so that it is easy to open later

To open the cork without any problems, you need to install it correctly the first time.

1. Make sure the neck is clean and dry, and if there are any drops of wine on it, wipe it with a napkin, which will improve the leakiness.
2. Put a cork in the neck of the bottle and press the seal tightly so that you don't have to hit the cork or screw it in -- just a little press.
3. Create a vacuum. On pump models like the Mijia Mini, press the top of the plug 3-5 times until you feel resistance. On Yeelight, the vacuum is created automatically when installed. Wait for an audible signal or notification in the app.

Check the leaks.

If the cork goes down after a few hours, it means the vacuum is not holding.

• 🔸 The unintegrated seal fit (check its integrity).
• 🔸 Cracks on the bottle (even microcracks violate leakage).
• 🔸 Cork wear (silicone loses elasticity over time).

On models with a sensor (for example, Yeelight Wine Preserver) you can track the vacuum level in the Mi Home application. If the pressure drops too quickly, the cork needs to be replaced.

How much is Xiaomi’s vacuum plug wine stored?

The main question that users are concerned about is: how much does a vacuum cork prolong the life of a wine? The manufacturer claims that the wine stays fresh up to 7-10 days, but in practice this period depends on several factors:

• 🍷 Type of wine: Red wines with a high content of tannins (for example, Cabernet Sauvignon or Sira) are stored longer than white or pink. Dessert and fortified wines can stand up to 2-3 weeks.
• 🍷 Vacuum level: If the cork holds the pressure poorly, the wine will oxidize in 2-3 days.
• 🍷 Storage temperature: Wine is stored in the refrigerator longer than at room temperature.
• 🍷 Cheap Xiaomi counterparts often let air through, reducing the shelf life to 3-5 days.

Here is an indicative shelf life table for different types of wine:

To maximize the freshness of wine, follow these tips:

• 🔹 Store the bottle in the refrigerator or cellar at a temperature of 10-15°C.
• 🔹 Minimize the contact of wine with air – pour it into a smaller bottle if there is little left.
• 🔹 Before tasting, give the wine a breath for 10-15 minutes after opening.

💡

If you keep wine for longer than a week, try adding 1-2 winestones (tartrate) to the bottle, which will absorb some of the oxygen and slow down oxidation.

Alternative ways to use vacuum plugs

Xiaomi's vacuum plugs can be used for more than just wine, but here are some non-obvious ways to use them:

• 🧉 Olive oil storage. Cork will prevent the oil from oxidizing and prolong its shelf life.
• 🍯 Preservation of honey or syrup. Vacuum will slow crystallization and prevent moisture absorption.
• 🧪 Laboratory experiments: Cork can be used to create vacuums in small containers (e.g., to extract fragrances).
• 🎨 Storage of paint or ink. Vacuum will prevent drying of acrylic or oil paints.

However, remember: for food, the cork should be thoroughly washed after each use, and for chemicals, it is better to allocate a separate cork (silicone can absorb smells).

Xiaomi corks are also sometimes used to vacuum-pack small items (such as seeds or spices), putting the item in a small bag, inserting it into a bottle and creating a vacuum.

💡

Do not use a vacuum plug to store aggressive liquids (vinegar, bleach, gasoline) Silicone and metal can react, which will lead to damage to the cork and health hazards.
