Precautions for placing glass wine bottles in hot weather

Apr 30, 2023

When placing glass wine bottles in summer, you need to pay attention to the following, otherwise it will explode:
Don't put glass wine bottles in the refrigerator: northerners like to burn wine in winter, which will warm the body, but in summer, don't put glass wine bottles in the refrigerator for the sake of feeling cold. At this time, as the temperature in the refrigerator decreases, the temperature of the gas in the bottle drops slowly, and its volume shrinks. At this time, the atmospheric pressure inside the bottle decreases, and the atmospheric pressure outside the bottle remains unchanged, so the outside air has a large impact on the bottle. The pressure of the cap is greater than the pressure of the air in the bottle on the cap; in addition, after the temperature drops, the metal cap shrinks when it is cold, so it is difficult to unscrew the cap.
Do not expose to the sun: the principle is the same as above, and the phenomenon of thermal expansion and contraction will also occur. Under sunlight, the temperature inside the bottle will rise, and there will be alcohol in the bottle, the solubility of CO2 will decrease, and it will escape from the glass wine bottle. The pressure inside the bottle increases suddenly, causing the glass wine bottle to burst;
Do not shake violently: CO2 gas and alcohol are dissolved in the liquor, and the pressure inside the bottle is higher than outside the bottle. When impacted, the pressure on the bottle wall will be unbalanced, and the glass wine bottle will burst, causing personal injury.
