Apples final the longest after they’re saved commercially in what’s known as a CA (managed environment) atmosphere, the place they will keep comparatively fresh-tasting for as much as a 12 months. While they will not final that lengthy in your house fridge, you may hold your apples contemporary and crisp for weeks at house by storing them within the fridge and sustaining the fitting stage of humidity by placing them in a crisper drawer, perforated plastic bag, or an unsealed plastic bag.
I’ve nostalgic recollections of going apple choosing with my household each fall as a baby within the Midwest. We’d all soar into the again of a pickup truck, the place we might sit on bales of hay because the truck drove us out to the apple orchard, my bowl-cut hair flapping within the wind. In retrospect, driving behind a truck on certain blocks of dried grass appears a bit unsafe—but it surely was the 80s, and we did not know any higher. The Golden Delicious apples we picked, nonetheless heat from the solar, had been actually one of the best apples I’d ever tasted: candy and tart, with a crispness no grocery retailer apple may match.
As an grownup, I’ve moved on from Golden Delicious apples (although there may be an heirloom selection known as Gilbert Golden Delicious that I’ve picked from an orchard in Sebastopol, California, that I am keen on). But I nonetheless crave apples, particularly these with the proper steadiness of sweet-tart taste, crispness, and juiciness. With apple season upon us, the query presents itself: What is one of the best ways to retailer apples in order that they keep contemporary and scrumptious for so long as potential?
An Apple’s Journey From Tree to Store
Autumn is apple season, however apples can be found year-round at most grocery shops. Once harvested, apples are sometimes saved commercially in what’s known as a managed environment (CA) atmosphere: a cool area usually between 30 to 40°F (-1 to 4°C) with 85 to 95% relative humidity and diminished oxygen ranges. This know-how makes it potential for grocery shops to promote apples year-round, and any apple you buy from a grocery store could very nicely have been saved for six months to a 12 months earlier than it even reaches the shelf.
The concept behind CA is to place apples “to sleep” by slowing their ripening. As they ripen, their cell partitions soften, and the inside cells start to dry out. Bite into an overripe apple, and the cell partitions break up moderately than rupture, providing you with a mealy chew. With a correctly ripe apple, the cells shatter in your mouth, releasing juice and delivering the crispness everybody loves.
Regulating the storage environment prevents apples from overripening and turning into mealy, but it surely’s a fragile steadiness, as every selection requires a unique atmosphere for optimum storage. Honeycrisp apples, for instance, are inclined to chilling damage (which can lead to discoloration or soggy flesh) and are greatest saved at 37 to 38°F (2.7 to three.3°C). Red Delicious apples, however, are greatest saved round 32°F (0°C).
Apple Basics
There are greater than 7,500 recognized forms of apples, however within the United States, solely about 100 of them are grown commercially. Popular apple varieties within the United States embody Gala, Granny Smith, Fuji, Golden Delicious, Honeycrisp, and Cripps Pink (usually bought below the model identify Pink Lady). In the US, apples are usually harvested from August to November, although precise timing varies by selection and rising area. For occasion, Honeycrisp and Gala are early-maturing apples, prepared in August and September, whereas Fuji and Granny Smith are normally harvested in October.
Because apple varieties fluctuate a lot—and since it is nearly unattainable to know the way lengthy an apple has already been saved—it is troublesome to foretell how lengthy any given apple will final in your kitchen. According to Jeff Colombini, chairman of the California Apple Commission and president of Lodi Farming, Inc.firmer, denser apples, akin to Gala, Fuji, Granny Smith, and Cripps Pink, are inclined to have higher storage life than softer varieties, like Red Delicious and Golden Delicious.
How to Shop for Apples So They Stay Fresh
Apples are a seasonal fruit. Although managed environment storage helps sluggish their ripening, apples proceed to ripen after being picked. In basic, if you’re shopping for from the grocery retailer, you probably will not know when your apples had been harvested. However, if you’re fortunate sufficient to get native apples from a close-by orchard or farmers market, the seller can probably let you know when the apples had been picked, and you’ll select those who had been harvested most just lately.
It’s greatest to pick agency apples with none blemishes. “The previous saying ‘one unhealthy apple spoils the bunch’ actually is true,” Wells says. Damaged or rotten fruit tends to launch extra ethylene fuel, a naturally occurring fuel and plant hormone that speeds ripening, leading to fruit that ripens and spoils quicker.
How to Store Apples, According to the Experts
Before I performed my very own checks on apple storage, I wished to see what consultants really helpful. According to a response to an e-mail I despatched to Out on a Limba small homestead farm in central Maine that grows uncommon, historic, and uncommon apples, one of the best ways to retailer apples is within the fridge, not at room temperature. Colombini agrees, including that it is best to maintain them within the coldest a part of the fridge to sluggish ripening. “The perfect storage temperature is 34°F (1°C),” Colombini says. “Most fridges are set to 40°F (4.4°C), so this isn’t a sensible resolution. However, storing apples within the backside drawer of a fridge is greatest as a result of that’s the coldest spot.”
If you’ve got ever purchased bagged apples from the grocery retailer, you may discover that the plastic is perforated, and the consultants I consulted suggest retaining them on this bag to sluggish their ripening and hold them juicy. The plastic helps retain moisture, whereas the holes enable the apples to breathe. If your apples did not are available in a perforated bag, many consultants suggest storing them in a regular produce bag that is left barely open so air can flow into.
As for whether or not you need to wash apples earlier than storing them, Matt Wells, vp of operations at Yes! Applessays that it’s not a good suggestion. Most apples even have a layer of epicuticular wax, a pure coating that helps stop moisture loss. “Washing proper earlier than you retailer them can really shorten their shelf life,” Wells explains, “as a result of it removes the apple’s pure protecting layer and might introduce additional moisture that hastens spoilage.”
The Tests
Armed with perception from the consultants, I purchased three widespread varieties—Granny Smith, Honeycrisp, and Cripps Pink—and examined how washing, refrigeration, and humidity affected their texture and taste.

Test One: Room Temperature and Washing
I took all three apple varieties and left them at room temperature (60 to 70°F/15.5 to 21°C), treating them in numerous methods:
- Apple unwashed
- Apple washed in 60°F (15.5°C) water
- Apple washed in 120°F (49°C) water
- Apple washed in an answer of 4 components 60°F water to 1 half distilled white vinegar
- Apple washed in an answer of 4 components 120°F (49°C) water and one half distilled white vinegar
- Apple unwashed and positioned subsequent to a banana
For my first take a look at, I left certainly one of every number of apple, unwashed, on my kitchen counter. I then washed the remaining apples utilizing the strategies described above and saved all of them at room temperature. I opted for water at two completely different temperatures; an answer of 4 components water and one half distilled white vinegar at two completely different temperatures; and an unwashed apple positioned subsequent to a banana to see if further ethylene fuel would affect the apples.
When I performed the same sequence of checks to find out one of the best ways to retailer cucumbers, I discovered that the pure wax on their pores and skin helped stop spoilage—and that washing them really shortened their shelf life. Although each professional I spoke with suggested in opposition to washing apples earlier than storage, I wished to see for myself how it might have an effect on the fruit.
The consultants had been proper: The unwashed apples fared greatest. After one week, the unwashed Granny Smith and Cripps Pink saved at room temperature held up pretty nicely. After three weeks, the washed apples carried out the worst—the Granny Smiths had begun to yellow and soften, whereas the Cripps Pink confirmed slight browning. I think the recent water and vinegar eliminated extra of the apple’s pure epicuticular wax, leaving them extra susceptible to moisture loss and spoilage.
The washed Honeycrisp apples confirmed probably the most dramatic change. Known for his or her crisp texture and juiciness, Honeycrisps are extra fragile than different varieties as a result of their bigger, juice-filled cells and skinny pores and skin. That skinny pores and skin additionally makes them susceptible to moisture loss. All of the Honeycrisps I examined started to shrivel after only one week, and by the third week, the apple washed with scorching water and vinegar had already begun to mould.
Test Two: Refrigeration and Humidity
After figuring out that unwashed apples held up greatest, I examined whether or not refrigeration and humidity made a distinction. These are the checks I ran:
- Apple by itself, on center fridge shelf
- Apple in a perforated plastic bag folded over, on center fridge shelf
- Apple in a sealed zip-top bag, on center fridge shelf
- Apple wrapped in a clear, dry paper towel in a sealed zip-top bag, on center fridge shelf
- Apple by itself, in a crisper drawer
For my second take a look at, I left certainly one of every sort of apple on a shelf in my fridge with no different gadgets other than the apples on the shelf. I then saved the remaining apples utilizing the strategies described above and saved them in my fridge: All of the apples had been saved on the fridge shelf, apart from the apple saved within the crisper drawer. In each case, the refrigerated apples seemed and tasted brisker than these saved at room temperature.
As within the first take a look at above, Honeycrisp apples proved to be probably the most fragile. The Granny Smith and Cripps Pink apples seemed almost an identical after three weeks within the fridge, no matter the place they had been positioned. The Honeycrisps saved in a perforated plastic bag, wrapped in a paper towel and sealed in a zip-top bag, and saved within the crisper drawer all appeared comparatively contemporary after three weeks. But the one left unwrapped on a shelf started to wrinkle and lose its colour.
The Honeycrisp saved in a completely sealed zip-top bag fared worst, growing a darkish bruise concerning the measurement of a pinto bean. It’s potential the apple had a small, barely seen bruise when saved, and the sealed bag trapped ethylene fuel, accelerating ripening and spoilage. This take a look at confirmed that apples saved in a controlled-humidity atmosphere—akin to a crisper drawer, a perforated plastic bag, or {a partially} open bag—lasted longer.

Key Takeaways and Conclusion
The outcomes made one factor clear: You should not wash apples earlier than storing them. As Wells famous above, washing apples earlier than storing removes the fruit’s protecting layer, shortening their shelf life. Refrigerating apples in a perforated produce bag or {a partially} open plastic bag, then inserting them in a damp space such because the crisper drawer, will probably yield the longest-lasting outcomes—even for extra fragile varieties akin to Honeycrisp.
If you propose to eat your apples inside 5 to seven days of buying them, you may retailer them on the counter, however all varieties will last more within the fridge. The greatest solution to retailer apples is in a perforated produce bag, ideally in your fridge’s crisper drawer. If you do not have a perforated produce bag, an everyday produce bag will work—simply depart it barely open to permit the fruit to breathe. Denser varieties, akin to Fuji, Granny Smith, and Cripps Pink, will last more than extra delicate sorts like Honeycrisp.
Quick Tips for Apple Shopping and Storage
- For most taste, attempt to buy apples out of your farmers market throughout the fall, which is when most apples are harvested.
- Buy agency apples which can be freed from blemishes and bruises.
- Avoid stacking apples, because the fruit on high could harm the fruit on the underside.
