Does Vodka Go Bad?  

The question ‘does vodka go bad?’ is one many will have asked at some point. You open the pantry, see a bottle that’s been there for years, and wonder how long vodka is good for. Does vodka expire, or is it still good to drink?

The answer is that vodka has an extremely long shelf life and, if left unopened, will last indefinitely. However, the quality of the drink can be affected if it’s not stored properly, or if it’s been exposed to air, humidity or other conditions. For prime results, it’s best to drink vodka between six months and two years after opening.

Labeling bottles to keep track of when they were first opened can help ensure you get the optimum flavor every time. This is especially true for flavored vodkas, which have a shorter shelf life and can have more noticeable changes in quality over time.

Does Vodka Expire or Deteriorate Over Time?

The alcohol content of most vodkas is around 40% ABV, or 80% proof. This means the drink is not susceptible to factors such as mold or bacteria, giving it a long shelf life. 

That said, once a bottle of vodka has been opened, exposure to air will begin to oxidize the liquid, which will cause deterioration in factors such as color, flavor profile, and even ABV (alcohol by volume). This is especially true if the vodka in question is not kept refrigerated.  

Exactly how long the vodka will last depends on a few factors. 

What Does ‘Going Bad’ Mean for Vodka?

When talking about vodka, going bad refers more to a decline in quality, which can affect the taste, aroma and coloring. While even vodka that has been open for several years will not become toxic, you will probably start to notice signs that the quality has deteriorated after a certain amount of time.  

Signs to look out for include: 

• Unpleasant aromas – If your vodka smells sour, musty, or simply unlike vodka, it is probably no longer fresh. 
• Bitterness – Most vodkas should not taste bitter. If the delicate flavor has become harsh, that’s a clear sign it’s lost its quality. 
• Discoloration – Standard vodka should be clear. If the liquid in your bottle has yellow, amber or brown discoloration, that suggests contamination or excessive oxidization. 
• Cloudiness – Similarly, if the vodka is clear but cloudy, it’s likely that it has degraded past its best. 
• Floating particles – Vodka with floating particles may have degraded to the point where the liquid has started to separate, with some elements coming out of the solution. 

The Shelf Life of Unopened Vodka

If a bottle of vodka is unopened and stored correctly, it has an indefinite shelf life – think 30 to 50 years. 

However, improperly stored vodka may still deteriorate, even when sealed. Factors such as extreme light or heat can cause chemical changes within the vodka. These can in turn have a negative effect on the flavor, aroma and appearance, which will noticeably reduce the quality of the drink. 

The Shelf Life of Opened Vodka

Opened bottles of vodka can also last indefinitely when stored correctly.  

However, the difference here is that degradations in quality will occur faster than with an unopened bottle.  

Once a bottle has been opened, it will naturally take in at least some oxygen and moisture. These two factors can result in changes to its characteristics, as well as ABV. You may notice a less distinctive flavor, unusual aroma, or reduced alcohol content.  

For flavored vodkas, deterioration tends to happen more rapidly – you might notice changes after just six months.

How to Store Vodka for Maximum Shelf Life

You can increase the longevity of your vodka by always storing it correctly. Optimal storage conditions extend the shelf life of the liquid.

Best Practices for Unopened Bottles

Vodka does not need to be refrigerated to maintain its quality, but it does need to be kept away from sources of extreme heat and light.  

We recommend storing unopened bottles of Absolut in cool, dark places such as a pantry or basement, where a steady temperature of between 55 and 60 degrees can be maintained. It is also better to store bottles upright, as interaction with the cork or bottle cap can cause more rapid deterioration. 

How to Store Opened Vodka

Optimal storage for opened bottles of vodka is not dissimilar to storage for unopened bottles. Keep upright, and store in the fridge or in a cool, dark place.  

One thing to remember is to always close the cap or recork securely after each pour. This helps reduce the amount of air that gets in, which reduces the rate of deterioration, as well as keeping out external contaminants.  

Does Vodka Evaporate?

Vodka can evaporate under certain conditions, although typically this would only result in around 1% loss in volume per year, and rarely affects the taste of the drink.

Even sealed bottles can see some evaporation if stored in a warm place, and an opened bottle in which the liquid has been exposed to air will evaporate more rapidly under the same conditions.

Vodka contains ethanol, which is a volatile molecule that can turn from liquid to gas when exposed to air, even at just room temperature. Opened or unopened, high temperatures are likely to increase the rate of oxidization and therefore evaporation.

What About Storing Vodka in the Freezer?

Some people choose to store vodka in the freezer, but with premium vodkas such as Absolut, this is not recommended.

Freezing cheaper vodka may help mute harsh flavors and improve the viscosity. However, with Absolut, the process is more likely to affect the minerality and subtle flavor notes. Ideal storage temperatures for Absolut are between 55 and 60° degrees, or typical room temperature. 

So, Does Vodka Expire?

All things considered, vodka does not technically expire, even after several decades of storage. However, it can deteriorate in quality, especially if exposed to air or not stored correctly.  

Keep caps sealed and store upright, at room temperature for unopened bottles and in the fridge for opened bottles. To preserve optimum quality, consume within two years from opening.
