When you put vodka into a fridge, several things will happen:
Cooling: The vodka will become colder due to the lower temperature inside the fridge. Vodka is typically best served chilled, so refrigerating it can enhance its taste and make it more enjoyable to drink, especially in warm weather.
Slower oxidation: By keeping vodka in a sealed container in the fridge, you can slow down the oxidation process. This means the vodka will retain its flavor and quality for a more extended period.
No freezing: Vodka has a much lower freezing point than water, which means it will not freeze in a standard household fridge. However, if you place vodka in a freezer with a significantly lower temperature, it may freeze or turn into a slushy consistency.
No significant change in alcohol content: The alcohol content of vodka will not change when refrigerated. It will remain the same as when you put it in the fridge.
No improvement in quality: Refrigerating vodka will not alter its taste or improve its quality, but it can make it more enjoyable to drink if you prefer it chilled.
Overall, keeping vodka in the fridge is a common practice and can enhance your drinking experience if you prefer cold beverages. Just remember to store it in a sealed container to prevent any unwanted odors or flavors from transferring to the vodka.
