What are the precautions for red wine storage

The storage environment should avoid vibration and odor interference. Vibration will disturb sediments and affect the aging process; red wine will absorb surrounding odors and should not be placed with items with strong odors such as food and detergents. Daily drinking wine can be stored in a cool place for a short period of time, but it is recommended to use a professional wine cabinet for precious vintage wines. The wine cabinet can accurately control temperature and humidity, provide a dark environment, and is more suitable for long-term storage of wine than ordinary refrigerators.

Inert gas protection: Inject inert gases such as nitrogen or argon into the bottle to isolate oxygen contact, suitable for short-term storage of high-end red wine.

The equipment penetrates the bottle stopper through a thin needle, injects inert gas (such as argon) to discharge the wine, while maintaining a balanced air pressure in the bottle, achieving "non-destructive wine extraction". After taking out the wine, the stopper automatically seals, and the wine can continue to age for months or even longer. This method can preserve the flavor of red wine to the greatest extent, but the equipment price is high (about 1,000 yuan) and the gas capsules need to be replaced regularly. It is suitable for wine cellars or professional collection scenarios.

Here are some precautions to store red wine correctly: Maintain a stable temperature: The storage temperature of red wine is very important. The optimal temperature is 12-18°C (54-64°F). Avoid exposure to extreme temperatures, such as high, low or drastic temperature changes, which may have a negative impact on the quality of red wine.

Storage time: Unopened bottles of red wine: It is best to drink it within six years from the year the grapes were picked, because a bottle of wine usually takes twice the time it takes to spoil. However, due to the high tannin and alcohol content of red wines, some can last for more than a year. Open bottles of red wine: If specific preservation techniques are not used, red wine will deteriorate about 3 days after opening the bottle.

Precautions to avoid storage in the refrigerator: Although the temperature of the refrigerator is constant, the humidity is not well controlled, which may cause the cork seal to fail. Stay away from under the sink: The humidity under the sink is too high and there may be odors, which will affect the quality of the wine. To sum up, the preservation of aged red wine requires comprehensive consideration of factors such as temperature, humidity, light and vibration to ensure that its quality is best maintained.

How do I hold the red wine in my hand?

The holding method of red wine needs to be adjusted according to the type of glass. When holding the glass, mainly hold the glass post or corner to avoid direct contact with the glass body and affecting the wine temperature and flavor. The specific operations are as follows: The characteristics of the holding cup shape of the champagne glass (sparkling wine glass): Champagne glasses are usually narrow and grooved design, and the body is long and thin. The purpose is to reduce the surface area of the wine and delay the dissipation of bubbles.

The general holding method is to pinch the foot of the cup with your thumb, index finger and middle finger. The ring finger and little finger are naturally retracted under the foot of the cup. The palm does not touch the body of the cup at all. It can stabilize the wine temperature and facilitate observation of the color of the wine and hanging the cup. Differences between special scenes and cup shape: 1) Champagne or sparkling wine glasses can be held at the foot or the bottom of the cup. Because the wine needs to be kept at a low temperature, the bottom of the cup is held more stably, and it can also avoid shaking so that bubbles can quickly disappear.

Prioritize holding the handle or foot of the cup. This is the most basic principle of holding the cup. The temperature of the hand will be transferred to the wine through the belly of the cup, destroying the original tasting temperature of the red wine, especially for light-bodied white wines and rosé wines. The impact on the flavor is particularly obvious. At the same time, fingerprints left on the belly of the crystal cup will destroy the visual beauty, especially in formal occasions.

When holding, you must hold the handle or holder of the wine glass, and never hold the body directly with your hands. Because the body temperature of the palm will be transferred to the wine, changing the suitable drinking temperature of red wine and affecting the flavor performance. The shaking amplitude and technique should be moderate. When shaking, the wine in the cup can flow evenly on the wall of the cup, and do not shake out the wine too much.

Changes in temperature will affect the volatilization of aroma substances in wine and the balance of taste, thereby changing its flavor performance.

What should I pay attention to when storing red wine

Air circulation: Choose a cool and ventilated place for storage to avoid the accumulation of odors in enclosed spaces, but it is necessary to prevent direct convection from accelerating the evaporation of wine. Humidity control: Use dehumidifying equipment or desiccant to deal with humid environments. Pay special attention to mildew prevention measures in the rainy season, but do not over-dry and cause the cork to become embrittlement. Choose an ideal place for storage: professional wine cellar (constant temperature and humidity system), basement (natural insulation layer), special wine cabinet (temperature and humidity adjustable).

Insufficient humidity: The humidity in the refrigerator is only about 30%, while the humidity of 60%-80% is required for red wine storage. A dry environment will cause the cork to crack and lose its elasticity, making it impossible to effectively seal the bottle opening, causing leakage or oxidation of the wine. Vibration interference: The continuous vibration generated by the refrigerator engine running for 24 hours will destroy tartrate and other substances precipitated in red wine, interfere with its aging process, and even accelerate chemical reactions, affecting flavor stability.

Temperature control: When storing red wine, the temperature should be well controlled. The best storage temperature is about 14 degrees. The temperature should not be too high, as the flavor will dissipate under high temperatures. Even if the temperature is too low, it is best to ensure a constant temperature. Protection from light: Whether it is light or natural light, it will accelerate the oxidation of red wine and reduce its quality. Therefore, avoid all light when storing it and place it in a dark but not humid place.
