Fresh strawberries can sometimes release a compound called methyl anthranilate, which is responsible for their characteristic sweet aroma. However, when stored in a confined space like a refrigerator, the volatile compounds from strawberries can interact with the cold air and create a strong odor (bad smell).

Is it normal for strawberries to stink?
Sign #4: The Strawberries Smell Off – When strawberries go bad, they have an alcoholic smell. Strawberries may also smell like rotten fruit. If strawberries smell bad, they should not be eaten, and a foul odor is a sure sign your strawberries are bad.
How do you keep strawberries from smelling in the fridge?
How to Store Strawberries – When stored properly in the refrigerator using one of the below methods, strawberries should stay fresh for up to one week. Always examine your berries for mold and other signs of spoilage before eating them.
Place in air-tight glassware: Transfer unwashed strawberries into a glass food storage container or mason jar and make sure it’s sealed tight. Paper towel method: Place a clean, dry paper towel in a container and put unwashed strawberries on top. Close the lid and place the container in the refrigerator. Rinse with vinegar solution: Soak strawberries in a vinegar solution (one-part white vinegar and three parts water) for a few minutes. Then drain them, pat them dry, and place them on a clean paper towel in a glass container. Loosely place the lid on and store in the refrigerator.

How can you tell if strawberries have gone bad?
Signs of Rot in Strawberries – Look for these signs to see if your strawberries have gone bad.
- Mold – older strawberries may develop white, dark brown, or black mold. The mold may be furry or look wet. It can be on the red part of the berry or the leaves.
- Soft Spots – rotten strawberries may have mushy spots. The mushy spots may be a slightly darker red or brown.
- Discolored Leave s – if the leaves at the top of the strawberry are turning yellow, are crinkly and brown, or have mold on them, they may be too old to eat. Yellowing or browning leaves are a sign the strawberries are past their prime.
- Smell – if the strawberries have a strong smell that’s acrid or ammonia-like, they are past their prime and shouldn’t be eaten. They won’t taste good and they may make you sick.
Why do my strawberries smell sour?
Everyone loves the first bite of a sweet, ripe strawberry. If your strawberries haven’t been producing the sweetness level that you were expecting, there could be an explanation. In most cases, it’s the strawberry’s inability to fully develop that leads to a sour taste.
- If the weather was cold, cloudy, or rainy during the growing season in May and June, or if temperatures soared to extreme levels, then your berries could be sour or bitter in response.
- Poor soil conditions, low sun levels, and planting at the wrong time can all lead to sour or bitter harvests.
- Overcrowding and unpruned plants can also produce poor crop yields.
So, what can you do to produce high-quality, sweet strawberries? First, choose the right kind of plant. Jump to:

Why do my strawberries smell fermented?
Old strawberries can get boozy – In the meantime, you might notice an alcohol-y flavor in older strawberries. That happens because cells inside of the strawberry, still living and breathing, can’t get the oxygen they need to keep running the strawberry engine (Yep, oxygen.
- The strawberry plant takes in carbon dioxide and releases oxygen for daytime photosynthesis, but takes in oxygen for round-the-clock respiration).
- So, they resort to no-oxygen-required fermentation as a backup energy source.
- Fermentation produces alcohol.
- A high internal alcohol content can make a strawberry taste like a vodka shot.
As strawberries age, they also give up some of their best stuff. So, you’ll get less Vitamin C from a strawberry like the ones pictured here, but with fiber and other components, it won’t be a complete nutritional wasteland. So, give it an assessing nibble and then make an informed choice.

Strawberries give you that sinking feeling?
Why do strawberries taste bad now?
The flavor of most fruits and vegetables is influenced by weather conditions. In regards to strawberries, warm sunny weather produces the most flavorful fruit. When the weather is extremely hot, the berries may have a slightly bitter taste. Strawberry plants produce smaller quantities of sugars when the weather is cool and cloudy.
What happens if I accidentally ate a rotten strawberry?
Is it OK to eat moldy strawberries? – If you find white fluffy stuff on your berries that looks a bit like cotton candy, that is mold. Mold is a fungus with spores that feed on the berries and grow thin threads that can look like fluff or cotton. This particular type of mold is common among fruits and is known as Botrytis fruit rot or gray mold,
- While moldy strawberries are unlikely to harm you, they can make you sick if you are allergic to molds in general, according to the USDA,
- And since berries are a soft-fleshed food, unlike apples or pears, it is not safe to simply cut away the moldy part, since the spores have likely gone into the flesh of the berry.
If a berry is bruised, but does not show any signs of mold, the bruised part can be trimmed away. A moldy strawberry should be thrown out. If you happen to accidentally eat a moldy strawberry, you’ll know it because, usually, moldy strawberries will have an off flavor that is a bit sour and acidic and may remind you of blue cheese.
The off taste is nature’s red flag that your red berries are bad, if you missed the visual mold. A small amount of this mold is unlikely to make you sick. If you ate a larger amount, you might have some signs of gastric distress similar to mild food poisoning, but it should resolve on its own, and is not toxic or especially dangerous, just uncomfortable.

Is strawberry naturally sour?
Michael Mosley tests why strawberries taste sweet when they’re low in sugar
Strawberries are one of the most luscious and versatile fruits, distinctively loved around the world for their sweet flavour.Ironically, the strawberry is also regarded as a health food that can be consumed in large proportions compared to other sweet-tasting fruits because of its low sugar content.According to, one cup of raw strawberry halves only contains 49 calories and seven grams of sugar.Science journalist, Dr Michael Mosley tests the actual sweetness of strawberries the new SBS three-part series Michael Mosley’s Secrets of Your Food by conducting an experiment to compare the sugar content of blueberries to strawberries in episode two.
“That means contains nearly half as much sugar per gram as there is in blueberries: I’m genuinely surprised by that.” Dr Mosley squeezes a few drops of juice out of each handful of ripe fruit into a petri dish. He then uses a refractometer to test the sugar level of fresh strawberry and blueberry juice.
What happens when light passes through any liquid is that it gets bent,” Dr Mosley says in episode two (scroll on down to watch the entire episode online via SBS On Demand). “The more sugar there is in that liquid, the more will get bent.” He first tests blueberry juice, which yields a sugar score of 13.
Strawberry juice is then tested, producing a score of eight. “That means contains nearly half as much sugar per gram as there is in blueberries: I’m genuinely surprised by that. So why is it that a strawberry tastes so sweet when it contains that much sugar?” The answer is complicated but fascinating.
- Botanist and show co-host, James Wong, explains that strawberries actually have a very high acid content.
- Wong measures the pH of fresh strawberry juice to test its acidity.
- With seven being perfectly neutral and one being very acidic, strawberries sit at 3.5.
- Strawberries reap the same acidic measure as grapefruit, despite tasting a lot sweeter.
To put this figure in perspective, vinegar yields a pH of 2.9 and black coffee has a pH value of five. “Strawberries have a cunning ability to hide their acidity,” says Wong. He adds that strawberries also don’t start out as sweet red-coloured fruits.
- Strawberry plants have specifically evolved this sweet succulent fruit to encourage animals to eat them,” explains Wong.
- That’s because when these seeds pass through the digestive tracts of an animal, they are deposited – with a bit of fertiliser – far and wide, helping the strawberries’ empire grow.” “Strawberries have a cunning ability to hide their acidity.” But, he says, this only works when the seed is fully mature and ready to sprout.
Up until this point, strawberries are green and full of acid that makes them taste sour. The sour flavour of an unripe strawberry is a deliberate animal deterrent. “The brain interprets this taste as unpleasant and a sign that the food could be spoilt or unfit to eat,” says Wong.
“It’s a biological reaction that plants use to their own ends: a taste strong and repellent enough to put most animals off. “But just at the right moment when the seeds have matured, the strawberry needs to mask this acidity to make it more palatable. All the acid is still there but the fruit becomes flooded with sugar, produced when hormones from the seeds announce they are ready to be eaten.
The sugars react with other plant molecules and make attractive red pigments that say ‘eat me’.” It’s estimated that the sugar content of strawberries increase from five percent in unripe green fruit up to nine per cent when fully ripe, according to an article in based on studies from University of Birmingham.
What do fresh strawberries smell like?
The chemistry of taste and smell – When I was young – in the 1950s – you only saw strawberries in the shops for a couple of weeks of the summer, roughly coinciding with Wimbledon. Now we have them all the year round. This is because strawberry breeders have been aiming for fruit with particular (and marketable) properties such as uniform appearance, large fruit, freedom from disease and long shelf-life.
But by concentrating on genetic factors that favour these qualities, other genes have been lost, such as some of the genes responsible for flavour. The balance of sweetness and acidity is very important to the taste of a strawberry. As strawberries ripen, their sugar content rises from about 5% in unripe green fruit to 6–9% on ripening.
At the same time, the acidity decreases, meaning ripe strawberries taste much sweeter. The ripening process is controlled by a hormone called auxin. When its activity reaches its peak, it causes the cell wall to degrade and so a ripe strawberry becomes juicy as well as sweet.
- At the same time, gaseous molecules from the strawberries make their way up the back of the throat to our nose when we chew on them, where they plug into “smell receptors”.
- But how do scientists know which molecules are responsible for taste and smell? More than 350 molecules have been identified in the vapour from strawberries – and around 20 to 30 of those are important to their flavour.
Unlike raspberries, there is no single molecule with a “strawberry smell”, So what we smell is a blend – these molecules together give the smell sensation we know as “strawberry”. Chemists made up a model strawberry juice containing what they thought were the most important odorants, at the same concentration found in the original juice extract.
- Sensory testers agreed that this model closely matched the real extract.
- They then made up a series of new mixtures, each containing 11 of the 12 main odorants, with a different molecule missing from each.
- The testers could therefore find out if omitting that molecule made any difference to the odour.
For example, leaving out 2,5-dimethyl-4-hydroxy-3(2H)-furanone or (Z)-3-hexenal was noticed by virtually all the testers – and omitting compounds known as esters – chemical compounds – such as methyl butanoate, ethyl butanoate or ethyl 2-methylbutanoate were also spotted by most. Common or garden strawberry.

They can make up 90% of the aroma molecules from a strawberry.
Why do my strawberries smell like alcohol?
As fruits, mainly berries/grapes, ripen, the juice actually goes through a fermentation process and it becomes alcohol.
