Does Whiskey Go Bad? A Guide to How Long Whiskey Can Last

While some may think that whiskey lasts forever, the truth is that it can go bad over time. The question is, does whiskey go bad, and if so, how can you tell?

The answer is yes, whiskey can go bad, but it depends on how it is stored. Exposure to light, heat, and air can all destroy the quality of your whiskey. The good news is that if stored properly, whiskey can last for years and even decades.

In this article, we will discuss the factors that can cause whiskey to go bad, how to tell if your whiskey has gone bad, and how to properly store your whiskey to ensure it stays fresh for as long as possible.

How Long Whiskey Lasts

In our experience, an unopened bottle of whiskey can last indefinitely if stored in a cool, dark place. However, once opened, the whiskey will start to oxidize, which can affect its flavor. Oxidation happens when the whiskey comes into contact with air, and it can cause the whiskey to taste sour or stale.

Ideally, you should finish a bottle of whiskey within 6-8 weeks of opening it in order to enjoy the absolute most intense flavors.

However, an open bottle of whiskey can last for years and decades without going bad when stored in an ideal location. The less you have in your bottle, the less time you’ll have to enjoy it before it goes bad.

By following these tips, you can ensure that your whiskey lasts as long as possible and retains its delicious flavor.

Factors Affecting Whiskey Shelf Life

Storage Conditions

Storing the whiskey play a crucial role in its shelf life. Whiskey should be stored in a cool, dark, and dry place, away from direct sunlight and heat. Exposure to sunlight and heat can cause the whiskey to lose its flavor.

Also, high humidity can cause the cork to expand, allowing air to enter the bottle, while low humidity can cause the whiskey to evaporate.

Exposure to Air

When whiskey is exposed to air, it undergoes a process called oxidation. Typically, it can cause the whiskey to lose its flavor and aroma. That’s why it’s important to keep the whiskey bottle tightly sealed when not in use.

Additionally, in our experience its best to finish an opened bottle of whiskey within 6-8 weeks to enjoy the most intense flavors.

Temperature Fluctuations

Extreme temperatures can cause the whiskey to expand and contract, which can affect the seal of the bottle. This can allow air to enter the bottle, which will oxidize the whiskey. Therefore, it is important to store whiskey in a place where the temperature is consistent.

Signs of a Bad Whiskey

When it comes to determining whether a whiskey has gone bad, there are several signs to look out for. Here are a few indicators of whiskey:

  • Off Smell: A bad whiskey may have a strong, unpleasant odor. If the whiskey smells sour, musty, or like acetone, it is likely past its prime.
  • Off Taste: Another telltale sign of a bad whiskey is a bad taste. A whiskey that has gone bad may taste harsh, bitter, or sour. If the whiskey tastes significantly different than it should, it may be time to toss it.
  • Change in Color: Whiskey that has gone bad may also have a noticeable change in color. If the whiskey appears cloudy, or if there are visible particles floating in the liquid, it may be time to get rid of it.
  • Sediment: Over time, whiskey can develop sediment in the bottle. While this is not necessarily a sign that the whiskey has gone bad, it can be an indication that it has been sitting around for a while.
  • Damaged Cork or Seal: If the cork or seal on the whiskey bottle is damaged or broken, it can allow air to enter the bottle and cause the whiskey to spoil.

It is important to note that not all of these signs may be present in a bad whiskey. In some cases, the only way to know for sure if a whiskey has gone bad is to taste it.

How to Properly Store Whiskey

1. Keep it in a cool, dark place

Whiskey should be stored in a cool, dark place, away from heat and light. Exposure to light or heat can cause the whiskey to deteriorate. Ideally, whiskey should be stored in a cabinet or pantry, but not above the oven, as it can become too warm.

2. Avoid a humid place

Humidity can can cause the cork to expand, allowing air to enter the bottle and spoil the whiskey. Therefore, whiskey should be stored in a dry place with a stable, non-extreme temperature.

3. Store it upright with the bottle tightly closed

Whiskey should be stored upright, not on its side. Storing the bottle on its side can cause the cork to dry out and shrink, which can lead to air entering the bottle and spoiling the whiskey. It should be stored with the bottle tightly closed to prevent air from entering the bottle.

5. Avoid temperature fluctuations

Temperature fluctuations can also damage whiskey and should be stored in a place with a stable temperature.

6. Don’t store it for too long

Whiskey does not improve with age once it has been bottled. Therefore, it is not necessary to store whiskey for a long time. In fact, storing whiskey for too long can cause it to lose its flavor and aroma.

By following these tips, whiskey lovers can ensure that their favorite drink remains in good condition and retains its quality and flavor.

Can you drink 50 year old whiskey?

Yes, it is safe to drink 50 year old whiskey as long as it has been stored properly and has not gone bad. However, the flavor profile of the whiskey may have changed significantly over time and may not be as enjoyable as it once was.

How can you tell if whiskey has gone bad?

Whiskey that has gone bad may have a sour or musty smell, or it may appear cloudy or have sediment at the bottom of the bottle. If the whiskey has a strange or unpleasant taste, it may have gone bad as well.

How to store whiskey after opening?

To store whiskey after opening, it is important to keep the bottle in a cool, dark place away from direct sunlight and heat. The cap should be tightly sealed to prevent oxidation, and the bottle should be stored upright to prevent any potential leakage.

Does whiskey get better with age?

Whiskey can improve in flavor and complexity as it ages in barrels, but this does not necessarily mean that older whiskey is always better.
