Does Moonshine Go Bad (Check This!)

The thought of whether moonshine goes bad has probably crossed your mind numerous times. Despite moonshine being an incredibly shelf-stable product and excellent preservative, it can go bad. When improperly stored–exposed to heat, kept in plastic containers, or left to oxidize–the spirit can eventually become contaminated, lose its potency and become the perfect home for bacterial growth, making it less favorable to drink.

In this post, we’ll discuss the factors that affect the integrity of moonshine, cues that yours has gone bad, and how to prevent spoilage. 

Does Moonshine Go Bad?

Moonshine can go bad over time. When improperly stored–exposed to heat, kept in plastic containers, or left to oxidize–the spirit loses its potency and leads to bacterial growth, making it less favorable to drink.

How Long Does Moonshine Stay Good For?

Let’s take a quick look at how long you can expect different types of homemade spirits to last

Homemade Moonshine:

Homemade moonshine typically has a long shelf life. Because it has high alcohol content, it’s stable. You can enjoy your drink several years after you’ve made it. But, if you add flavorings–fruit, sugar–they can reduce its longevity, requiring you to consume it within a year.


Being a neutral spirit, vodka has a long shelf life. Vodka can last if kept clean and away from oxygen.


Because gin is flavored and re-distilled, it can last indefinitely. Once open, it’s best to consume it within a year or two for optimum flavor.

Whiskey and Rum

Whiskey and rum can remain drinkable and enjoyable for many years, even decades, if stored in suitable conditions.

Can You Drink Old Moonshine? (Our Opinion)

You can drink old moonshine if you’ve stored it properly, and it remains unopened until you decide to consume it. Once open and improperly stored, it results in contamination and oxidation (more on this below).

How Can You Tell If Moonshine Is Bad?

Here are some indicators that moonshine is bad. 


Moonshine should have a clear appearance. If it appears cloudy, discolored, or contains sediment, it indicates spoilage. 


Spoiled moonshine may emit foul or off-putting odors because of the presence of contaminants or bacteria. A strong acetone or vinegar-like smell is a potential sign of spoilage.


Bad moonshine may have a harsh taste, or taste significantly different from its original profile. If the flavor seems off or rancid, it’s likely gone bad.

Inspect the Container/Bottle for Corrosion or Damage

Are there any signs of corrosion, leakage, or damage? This can compromise the quality and safety of the spirit.

5 Considerations to Keep Moonshine from Going Bad:

To preserve the quality of your spirit, consider the following factors:

  1. Storage container (plastic vs. glass vs. metal)
  2. Keep oxygen out
  3. Keep out of sunlight and in a cool location
  4. Minimize loss through evaporation
  5. Understand aging

Storage container (plastic vs. glass vs. metal)

Avoid plastic containers as they can interact with the spirit and introduce unwanted odors and flavors. Plastic can leach antimony, phthalates, and lead, compromising the quality of your liquor and, potentially, your health. We suggest you use non-reactive materials such as glass or metal–specifically stainless steel. Glass is inert, so it won’t impart any flavor, while stainless steel is sterile and imparts little to no flavor to your drink. 

Keep oxygen out

Oxygen can accelerate the deterioration process. When alcohol reacts with oxygen, it undergoes oxidation. Oxidation converts ethanol into acetaldehyde and then into acetic acid. Acetic acid is responsible for the sour taste and aroma you’d find in spoiled alcoholic beverages. Use airtight lids to create a barrier between the moonshine and the surrounding air. 

Keep out of sunlight and in a cool location

Sunlight can degrade the quality of moonshine by promoting chemical reactions and causing off-flavors. Store your moonshine in a dark and cool place, away from direct sunlight or heat sources, to maintain its quality.

Minimize loss through evaporation

When alcohol evaporates, the concentration of alcohol in the remaining liquid increases. This can lead to a more potent taste. Also, it can alter the balance of flavors, resulting in a flat taste and a lighter mouthfeel. 

Understanding Aging (does it get better with time?)

While certain spirits like whiskey and rum can improve with aging, homemade moonshine may not necessarily benefit from extended storing periods. Because moonshine is generally unaged, leaving it in glass jars merely allows the compounds to marry for a couple of days, but anything longer than that, the spirit remains unchanged. If you want to harness the complexities of your moonshine, age in oak barrels or use inserts like oak chips. 


Moonshine can go bad over time, and its longevity varies depending on the type of spirit and storage conditions. Proper storage, including the choice of container and minimizing exposure to oxygen and sunlight, can extend the shelf life and retain the quality of your moonshine. If you suspect your moonshine has gone bad, inspect its color, smell, taste, and the presence of sediment.
