How long does vodka last in an open bottle at room temperature?

You should never store vodka at room temperature, especially in an open bottle. Here's why:

* Evaporation: Vodka is a highly volatile liquid, meaning it evaporates easily. Leaving it open at room temperature accelerates this process, making it weaker and less flavorful over time.

* Oxidation: Exposure to air can cause vodka to oxidize, which can lead to a change in taste and aroma. The vodka may start to taste "off" or even develop a vinegary note.

* Contamination: Bacteria and other microorganisms can easily enter an open bottle of vodka, particularly at room temperature. This can lead to spoilage and make the vodka unsafe to consume.

Proper Storage:

* Refrigerate: Store opened vodka in the refrigerator. This significantly slows down evaporation and oxidation.

* Airtight container: Always keep the bottle tightly sealed after opening.

* Shelf life: Refrigerated, properly stored vodka can last for several months to a year.

Important Note: Even if your vodka hasn't visibly changed, it's best to err on the side of caution and discard it if it has been open for an extended period.
