Is it bad to drink expired margarita?

Quick Answer

It’s generally not recommended to drink expired margarita mixes or pre-made margaritas. The alcohol and juice can go bad over time, leading to off flavors, texture changes, and potentially unsafe bacterial growth. How long a margarita lasts depends on ingredients and storage. Properly stored, unopened mixes can last 6-12 months past the expiry date. Pre-made margaritas should be consumed within 2-3 days. If the drink smells or tastes off, it’s best to discard it. Moderation is key even with “good” margaritas.

Does margarita go bad?

Like any food or drink, margaritas can go bad over time. How quickly they expire depends on the specific ingredients, how it’s made and stored:

  • Margarita mixes – Store-bought margarita mixes containing sugar and citrus juice can degrade in quality and grow mold if left for too long. Unopened, they typically last at least 6-12 months past the printed expiration date. Opened mixes should be used within several months.
  • Pre-made margaritas – Fresh margaritas from a bar or restaurant should be consumed soon for best flavor. The citrus juice can turn bitter and alcohol can oxidize if left for more than 2-3 days. Salted margarita glasses help extend shelf life.
  • Homemade margaritas – Depending on recipe, homemade margaritas without preservatives are only good for 1-2 days refrigerated. Added sugars help extend life but can throw off flavor.
  • Alcohol – Tequila and other liquors don’t really expire. However, oxidation and evaporation over years can slowly alter the taste. Very old liquor may not be toxic but will likely taste off.
  • Margarita mixers – Juices, sweeteners and water mixes can expire and ferment. Citrus and sweet & sour mixes last 1-2 weeks refrigerated. Discard if moldy or smells odd.

So in summary, the shelf life of margaritas depends on the specific ingredients, whether it’s store-bought or homemade, if it’s been opened, and how it’s stored. Refrigeration extends life by slowing deterioration. But general guidelines are 1-2 days for pre-made drinks, and under 1 year for unopened mixes.

Why do margaritas expire?

There are a few reasons why margaritas can go bad over time:

Spoilage of juices and mixers

Margaritas contain fresh citrus juices like lime, lemon, and orange juice. These fruit juices contain sugars and compounds that can support mold growth and bacterial spoilage over time. Changes in acidity, off flavors, and texture are signs of spoiled juices.

Deterioration of flavors

The complex balance of sweet, sour, salty, and bitter flavors in a margarita can be disrupted as certain ingredients degrade. Alcohol and juices can oxidize, while preservatives and sugars can break down. This leads to altered flavors.

Growth of bacteria and yeast

Yeasts and bacteria naturally present on fruit can multiply over time, especially if left unrefrigerated. This can lead to fermentation, mold growth, and gas production, resulting in off tastes, odors, and carbonation.

Breakdown of compounds over time

Vitamins, flavor and aroma compounds naturally begin to break down and deteriorate in fruit juices and teas. This reduces the fresh taste. Light, oxygen, and heat speed up these reactions.

Evaporation of alcohol and water

Alcohol content can diminish over time as ethanol evaporates from the margarita mix. Water also gradually evaporates, increasing the relative sugar and acidity. This concentrates the flavors.

So in summary, the natural spoilage of juices, changing chemistry of ingredients, and microbial activity all contribute to the limited shelf life of margaritas. Proper refrigerated storage helps slow these processes.

How long do margaritas last?

The exact shelf life of margaritas depends on the specific ingredients and type:

Store-bought margarita mixes

Unopened, commercially sealed margarita mixes and concentrates typically stay fresh for:

  • 6-12 months past the printed expiration date when stored in a cool, dark pantry
  • 1-2 years when refrigerated after opening

Look for changes in color, aroma, fizz, and clumping or mold growth before using expired mixes. Discard if any smell or look off.

Pre-made and restaurant margaritas

Freshly blended margaritas don’t keep long:

  • 2-3 days maximum when refrigerated in a sealed container
  • 1-2 days for drinks with fresh-squeezed juice

Salting the glass rim helps preserve carbonation and freshness. Discard any separating, curdling, or flat-tasting drinks.

Homemade margaritas

Margaritas mixed at home have the shortest shelf life:

  • 1-2 days when refrigerated
  • 2-3 hours at room temperature

They lack the preservatives of commercial mixes so spoil fastest. Avoid letting homemade margaritas sit out.

Liquor shelf life

Unopened tequila and other distilled spirits last indefinitely. After opening, they remain good for:

  • 1-2 years stored in a cool, dark place
  • 3-5 years if refrigerated

So in summary, drink fresh margaritas fast for best quality and safety. Discard any bottles or mixes long past expiry. Refrigeration helps extend shelf life after opening.

How to tell if margarita has gone bad?

Watch for these signs that a margarita has spoiled and should be discarded:

  • Altered color – Turned darker, cloudy, or dulled
  • Off aromas – Smells sour, moldy, rotten, or fermented
  • Changed texture – Separated, curdled, slimy, or foamy
  • Carbonation – Excessive bubbles from fermentation
  • Poor taste – Sour, bitter, sharp, or generally off flavors
  • Mold – Fuzzy growth anywhere in drink or along top
  • Rancid oil – Soapy or rancid taste from oxidized fats

Always inspect pre-made margaritas before drinking. Discard anything that smells or appears odd without tasting. Don’t drink margaritas stored for long periods even if they seem ok. Not ideal for health or enjoyment.

Can you drink expired margarita mix?

It’s generally not recommended, but drinking margarita mix slightly past its expiration date likely won’t make you sick, as long as it’s been stored properly:

  • Unopened mixes can last 6-12 months past printed date if kept cool and dark
  • Open mixes can last up to 1 year refrigerated
  • Discard if any odd separation, color changes, or clumping
  • Small taste test to check for flavor and alcohol bite
  • May need added tequila to account for evaporated alcohol

Expired mixes that are badly discolored or smell off should be discarded. Consuming spoiled, moldy drinks could potentially cause foodborne illness.

The printed expiration dates are simply guidelines, not safety cut-offs. But quality and taste suffer more the longer past date they’re consumed. Stick to small quantities of mixes slightly past date, refrigerated and properly sealed. Discard and fresh replacements as better option.

Dangers of drinking expired margarita

While drinking margarita a short time past its prime won’t make most people sick, there are some potential risks consuming truly expired, spoiled margaritas:

  • Foodborne pathogens – Mold, salmonella, E. coli from spoiled ingredients
  • Gastrointestinal illness – Nausea, vomiting, diarrhea
  • Allergic reactions – To molds or histamines in old ingredients
  • Toxic methanol – From fermented pectins in old citrus juice
  • Liver issues – High acidity can irritate liver when alcohol present
  • Off tastes – Unpleasant flavors ruin the drink experience

Again, these risks apply primarily to margaritas long past their prime. But it’s impossible to tell just by looking or smelling if dangerous pathogens are present. So when in doubt, throw it out. Making fresh drinks is safer.

Consuming margaritas with higher alcohol content can also impair judgment and coordination even if not spoiled. As with any alcohol, moderation and common sense are key. Don’t drive or operate machinery after drinking margaritas.

Tips for proper margarita storage

Follow these storage tips to help extend the shelf life of margaritas:

  • Refrigerate mixes, juices, and pre-made drinks after opening
  • Keep unopened mixes and bottles in a cool, dark pantry or cabinet
  • Don’t let margaritas or mixes sit at room temperature more than 2 hours
  • Use clean glasses and utensils to avoid contamination
  • Salt rims of glasses to help preserve carbonation
  • Transfer mixes to airtight containers to limit air exposure
  • Check regularly for any signs of spoilage
  • Discard open citrus juices after 1 week
  • Avoid direct sunlight which degrades flavors faster

Proper refrigeration at 34–40°F (1–4°C ) is key for slowing the natural deterioration process. Discard anything that smells or looks off rather than take a chance.

Can you freeze margaritas?

Yes, margaritas can be frozen for longer term storage:

  • Freeze drink mixes or ready-made margaritas in airtight containers
  • Lay plastic wrap directly on surface to prevent freezer burn
  • Thaw overnight in fridge before using for smooth texture
  • Add extra tequila after thawing to account for alcohol loss
  • Mixes last 6-8 months frozen; margaritas 2-3 months max
  • Don’t freeze margaritas with cream or dairy ingredients

Freezing stops the deterioration process and extends shelf life. But texture and flavor will still degrade over time. Use frozen margaritas within the time frames above for best quality.

Shaking or blending after thawing reconstitutes texture. Add extra tequila or liqueurs to make up for alcohol lost through evaporation during freezing.

Do margaritas go bad if left out overnight?

Yes, margaritas can go bad if left out of the refrigerator overnight. The shelf life is shortened significantly:

  • 1-2 hours maximum at room temperature
  • Rapid growth of bacteria and fermentation
  • Faster deterioration of fresh juices and mixes
  • Accelerated oxidation of alcohol
  • Increased risk of contamination from environment

Leaving margaritas out for over 2 hours is not recommended. The drink should be stored promptly in the refrigerator or discarded if left out overnight.

Even when refrigerated after sitting out, deterioration will have accelerated, shortening shelf life to just 1-2 days total. Always best to consume freshly made margaritas immediately, or store in fridge right away in sealed containers. Leaving out overnight risks foodborne illnesses.

Do margaritas expire if unopened?

Unopened commercially bottled margarita mixes generally stay fresh past expiry:

  • 6-12 months past printed date if stored properly
  • 2+ years lifespan for high quality tequilas and spirits
  • Higher acidity and alcohol act as preservatives
  • Eventually flavors degrade with prolonged storage

As long as the bottle seal is intact, unopened mixes and tequila won’t actually spoil or become unsafe to consume. However, taste and quality slowly diminish over time.

For peak freshness and flavor, adhere to the recommended time frames. Discard bottles long past date even if unopened. Once opened, refrigerate and use within several months.

So unopened margarita ingredients don’t necessarily expire. But storage conditions alter how long they retain optimum quality. Cool, dark storage extends shelf life best before opening.


Drinking expired or spoiled margaritas is generally not recommended, as aging ingredients can develop into unpleasant or potentially unsafe compounds over time. However, an unopened margarita mix stored properly may still retain quality and alcohol content for up to 1 year past its expiration date.

Pre-made margaritas last just 2-3 days refrigerated. Homemade drinks for only 1-2 days max. So consume freshly made margaritas fast for best flavor and food safety. Properly stored, unopened margarita mixes and tequila can go 1-2 years before major degradation. But for peak quality, it’s still best to stick to shelf life guidelines, refrigerate after opening, and avoid aging margaritas long past their prime.
