Can old vodka make you sick?


Vodka is one of the most popular spirits in the world. It’s a clear, high-proof alcoholic beverage that’s been around for centuries. Vodka is valued for its neutral flavor profile and mixability. This allows the vodka to take on the flavors of whatever it’s mixed with, without overpowering them.

Vodka is relatively low in congeners (flavor compounds) compared to other spirits like whiskey or brandy. This makes it less likely to result in severe hangovers. But one question people often have is: can old, expired vodka make you sick? Let’s take a closer look.

What Happens as Vodka Ages?

Vodka is known for retaining its quality and taste for many years. Unlike wine or whiskey, vodka does not improve with age. That’s because there are no congeners or flavor compounds that can mellow out over time.

However, vodka can degrade in quality if it’s stored improperly. Extreme temperature fluctuations, exposure to sunlight, or oxygen getting into the bottle can cause vodka to deteriorate faster.

As vodka ages, a few subtle changes may occur:

– Slight evaporation of alcohol, making the vodka decrease in proof over many years
– Possible oxidation, which could dull flavors and aromas
– Absorption of flavors/aromas from the bottle or environment (like plastic or dust)

But in most cases, the vodka should remain safe to consume even if it’s a few years past its expiration date. The alcohol content provides protection against microbial growth.

Does Vodka Go Bad?

Unlike beer or wine, distilled spirits like vodka do not really “go bad” in the traditional sense. Beer and wine contain sugars and compounds that can spoil or ferment over time as bacteria and yeast grow.

But properly distilled vodka is high enough in alcohol (around 40% ABV) that no microbes can survive and reproduce. So vodka does not spoil or become dangerous to drink even years after the bottle has been opened.

However, vodka can start to taste “off” if stored improperly for a very long time. The main signs that vodka has gone bad are:

– Discoloration – Vodka should be crystal clear. Yellow/brown hues indicate contamination.
– Particles or bits floating around – This is also a sign of contamination.
– Off aromas or flavors – Such as bitter, rancid, rotten egg, or rubbery smells.
– Flat or stale taste – Oxidation can make vodka taste lifeless.

If you notice any of these warning signs, it’s best to err on the side of caution and discard the vodka. While it’s unlikely to make you sick right away, degraded vodka likely won’t taste good.

Can Expired Vodka Make You Sick?

Vodka that’s past its expiration date shouldn’t inherently make you sick. The expiration date relates more to quality than food safety.

The “expiration date” on a vodka bottle refers to how long the producer can guarantee optimal taste and flavor. So expired vodka may start to have some muted aromas or a decline in quality, but it’s very unlikely to be dangerous.

In fact, unopened vodka lasts indefinitely due to the high alcohol content and lack of perishable ingredients. Once opened, vodka can last around 10 years before substantial deterioration.

Of course, improperly made vodka with contaminants or a lower alcohol content could potentially go bad faster. But as long as the seal is intact, commercial vodka lasts 1-2 years or more past its expiration date before quality is significantly impacted.

So fear not if you discover an old bottle of Smirnoff hidden away that’s a few years past its prime. As long as it looks and smells normal, bottom’s up! Just be aware that the taste likely won’t be as crisp and clean as a fresh bottle.

When Does Vodka Actually Go Bad?

Because vodka has an almost indefinite shelf life, it can be difficult to pinpoint exactly when it has crossed the line from safe to consume to bad vodka. Here are a few signs that your bottle of vodka has truly gone bad and should be discarded:

– Changes color – Clear vodka will turn yellowish, gold, or brownish if it has gone bad. This indicates chemical reactions and contamination.

– Clumps, particles, or filmy residue – Bits floating in old vodka or stuck on the sides of the bottle are never a good sign. Toss it.

– Strong chemical or bitter smells – A heavy, potent odor like nail polish remover or rotten eggs signals the vodka is bad.

– Fermentation or carbonation – Bubbles in vodka and a yeasty smell can mean fermentation is occurring and it’s time to say goodbye.

– Mold – Usually visible as weird stringy bits or fuzzy patches. Definitely do not drink moldy vodka.

– Separation between liquor and water – If your vodka has distinct oily layers or the water separates, something has gone very wrong.

– A consistency other than clear liquid – If it becomes viscous, syrupy, or curdled, that’s a bad sign.

So if you notice any of the above issues with an aged, expired bottle of vodka, it’s best to err on the side of caution and properly dispose of it. Your liver will thank you.

How Long Does Open Vodka Last?

Once a bottle of vodka has been opened, its shelf life decreases substantially. Exposure to oxygen starts the clock for how long opened vodka will last before it goes bad. Here are some guidelines:

– Unflavored vodka lasts 3-6 months after opening.

– Flavored vodka or cream-based liqueurs last 2-3 months after opening.

– Homemade infused vodkas last 1-2 months after opening.

Vodka can last up to a year after opening if stored very properly in a cool, dark place and resealed tightly after each use. But quality will decline after 6 months.

If you notice any odd flavors, aromas, or visual changes after opening vodka, it’s safest to discard it even if it hasn’t reached the 3-6 month mark. Don’t take chances on drinking spoiled vodka.

How to Store Vodka Properly

Vodka’s long shelf life comes largely from its high alcohol content. But you can get the most longevity out of your vodka bottles by storing them properly:

– Keep tightly sealed – Replace caps promptly after pouring to minimize air exposure.

– Store out of direct light – Sunlight can accelerate aging and flavor deterioration.

– Maintain a stable, cool temperature – Avoid extremes of hot or cold, ideally keep around 70°F.

– Keep upright – Store vodka vertically if possible to minimize risk of leaking seals.

– Check for evaporation – Top off bottles that get down to 1/4 full as more air speeds aging.

– Don’t store on the floor – Keep on a shelf to minimize risk of explosions from temperature shifts.

Following these simple vodka storage rules will help retain optimum flavor and quality for as long as possible.

Can Freezing or Refrigerating Vodka Extend Its Life?

Does chilling or freezing vodka make it last longer? The short answer is no. Freezing is not an effective way to halt vodka’s slow deterioration. Here’s why:

– Alcohol’s freezing point is much lower than water’s, so vodka won’t fully freeze. It just becomes thick and viscous.

– The freezing process can actually accelerate oxidation and flavor deterioration over time.

– Bottle seals can break or crack due to vodka expanding as it freezes, causing leaks.

– Repeated freezing/thawing leads to “temperature shock” which can degrade vodka faster.

– Condensation when thawing can lead to added water content, diluting the vodka’s flavor.

So avoid freezing your vodka. Refrigeration is fine for chilling vodka before drinking, but won’t significantly prolong its shelf life once opened. The best way to store vodka is at stable room temperature out of direct light.

Should You Filter Old Vodka Before Drinking?

Some people recommend filtering cloudy, old vodka through a charcoal or Brita filter before drinking to improve the taste. Does it work? Here’s the truth about filtering aged vodka:

– It can remove some unpleasant tastes or smells from deterioration.

– But it won’t remove methanol, acetone, or other toxic chemicals if they’re present.

– Filtration also won’t help if the vodka has taken on a rancid or rotten flavor note.

– At best, it makes bad vodka taste mildly better. But it’s still bad vodka.

So try filtering if you want, but it’s not a magic bullet for resurrecting gone-bad vodka. The best solution is to start with fresh, clean vodka and store it properly in the first place.

If vodka ever changes color, smells off, or tastes unpleasant, your best bet is to err on the side of caution and discard it. Aging vodka is not like aging wine or scotch. It does not improve with time.

Signs of Contamination in Vodka

Vodka doesn’t really “go bad” in the traditional sense, but it can become contaminated and undrinkable over time. Here are some warning signs your vodka may have dangerous contaminants:

– Strange coloring – Yellow, gold, or brown hues indicate aldehyde or fusel oil contamination.

– Cloudiness – Hazy, non-transparent vodka could contain methanol or other toxins.

– Particles floating – Bits of mold, residue, or other solids signal contamination.

– Unusual separates – Oily layers or a divide between water and alcohol is abnormal.

– Off aromas – Nail polish, rubber, or rotten produce odors can mean toxic impurities.

– Soapy flavor – Saponification (soap-like tastes) likely means barrel leaching or metal contamination.

– Burning/numbing sensation – This symptom indicates high levels of harsh fusel oils or methanol.

The most common vodka contaminants are methanol and acetaldehyde. But plasticizers, metals, cleaning fluids, or other toxins could also find their way into bad vodka.

If your vodka exhibits any of the above signs, it’s safest to discard it entirely rather than risk drinking unknown toxins. Don’t take chances with possibly contaminated vodka.

How to Tell if Homemade Vodka is Safe

With the right equipment, it’s possible to craft vodka at home. But home distillation comes with risks if not done properly. Here’s how to tell if your homemade vodka is safe to drink:

– Use a quality still – Poorly constructed stills may leach metals or other dangerous impurities. Stick with reputable brands designed for spirits.

– Verify alcohol percentage – Homemade vodka should be 60-95% alcohol to be safe for consumption after diluting. Use a proof and tralle hydrometer to test.

– Check odor and flavor – Smell and taste test a small amount for any “off” or harsh characteristics before drinking more.

– Do not distill to 100% – It must be diluted. Undiluted ethanol is toxic.

– Ensure methanol has boiled off – Discard any “foreshots” collected before the heart of the distillation run.

– Avoid metallic flavors – These indicate potential leaching from components of the still.

– Be vigilant about sanitation – Thoroughly clean equipment and use filtered water to prevent bacterial contamination.

Distilling vodka safely takes practice and care. When in doubt, it may be best to discard your batch and start over. Consuming improperly distilled vodka can have deadly consequences.

How to Dispose of Bad Vodka Properly

If you determine your old vodka has truly gone bad, disposal is an important final step. Here are some safe, proper ways to get rid of bad vodka:

– Pour it down the drain dilute – Run plenty of water to prevent build up of fumes.

– Use it as a household cleaner – Vodka can disinfect surfaces or shine glass.

– Add it slowly to a compost pile – Too much alcohol can harm compost biology so go slowly.

– Mix with cat litter – The litter will help absorb and dissipate fumes as it evaporates.

– Mix with yard waste before disposal – Sawdust, leaves, or wood chips help mitigate odor and seepage issues.

– Contact your local hazardous waste department – Some accept household alcohol and dispose of it safely.

Never dump large quantities of unwanted spirits directly into landfill trash or down your toilet. This can cause safety hazards. Instead, dilute and slowly introduce bad vodka into appropriate waste streams.


The shelf life of a vodka bottle is very long, but vodka can deteriorate in quality over many years of aging. Though it likely won’t make you sick right away, old vodka past its prime may have muted flavors and aromas. Once opened, vodka only lasts about 6 months before risk of oxidation and evaporation.

Signs that vodka has truly spoiled and may be unsafe to drink include odd colors, cloudiness, bitterness, and chemical odors. Contaminants or home distilling mistakes could introduce dangerous toxins like methanol. Always err on the side of caution when evaluating old, homemade, or off-smelling vodka.

With proper storage out of light and heat, unopened vodka can last up to a decade without substantial deterioration. But to enjoy vodka at its best, start with a fresh bottle and consume it within a year or two of opening. When it doubt, pour it out. A replacement bottle is a small price to pay to avoid the risks of bad vodka.
