It is generally safe to put a plastic bottle of vodka in the freezer. Vodka has a relatively low freezing point, typically around -16 to -27 degrees Celsius (-3 to -17 degrees Fahrenheit). Most home freezers operate at temperatures below this range, so the vodka should not freeze solid.
However, there are a few factors to consider:
Bottle material: Ensure that the plastic bottle you use is suitable for freezing. Most plastic bottles designed for beverages, such as vodka, can withstand freezing temperatures without cracking or leaking. Check the label or packaging of the bottle to verify if it is freezer-safe.
Bottle fullness: Leave some room in the bottle for expansion. Liquids tend to expand when they freeze, and if the bottle is completely filled, there may not be sufficient space for expansion, potentially causing the bottle to burst.
Freezing time: The freezing time for vodka in a freezer can vary depending on the freezer's temperature and the initial temperature of the vodka. It is recommended to leave the bottle in the freezer for a few hours or overnight to ensure it gets adequately chilled without freezing.
Remember to handle the bottle with care when removing it from the freezer, as the plastic may become more brittle in low temperatures. Always use caution when handling any frozen or cold objects to avoid injury.
If you prefer your vodka cold but not frozen, you can also consider storing the vodka in the refrigerator, which will keep it chilled without the risk of freezing.
