How long will opened vodka keep in fridge?

Opened vodka can be stored indefinitely in the fridge, as long as the bottle is kept tightly sealed to prevent evaporation and contamination. Vodka is a distilled spirit that is made from ethanol and water, and it does not contain any ingredients that will spoil or degrade over time. However, it is important to note that vodka can lose its flavor and aroma over time, so it is best to consume it within a few months of opening the bottle.
