How to Store Apples So They Keep for Months

Apples last longest cold, humid, and alone. At about 32°F (0°C) with 90–95 percent relative humidity, most varieties keep for months; at room temperature, most are past their best within one to two weeks, according to Iowa State University Extension and Outreach. The three things that matter most are temperature, humidity, and keeping apples away from other produce, since apples give off ethylene gas that speeds the ripening and spoilage of whatever sits near them. Variety matters too: a thin-skinned Gala behaves nothing like a thick-skinned Arkansas Black once either goes into a box. The rest of this guide covers how to get the conditions right at home, which apples are worth storing long-term, and what to do with a surplus that won’t fit in the fridge.

What temperature and humidity keep apples fresh longest?

Apples kept at 32°F last two to three times longer than apples kept at 45–50°F, Iowa State Extension reports, and low humidity causes them to dehydrate and shrivel even when the temperature is right. The target combination, per Iowa State and the eXtension Apple Harvest and Storage publication, is close to freezing with very high moisture in the air:

A standard refrigerator at 32–40°F (0–4°C) gets close, but its air is dry, so humidity has to be added back: a perforated plastic bag or the crisper drawer’s high-humidity setting both help. Commercial growers reach the same numbers with controlled-atmosphere rooms that also lower oxygen to roughly 3–5 percent, which slows respiration further and can stretch storage past six months, according to the eXtension Apple Harvest and Storage page. A home kitchen can’t replicate the reduced-oxygen part, but the cold and humidity half of the equation is within reach with a fridge, an unheated room, or an insulated chest.

Which apple varieties store the longest?

Skin thickness and natural keeping ability vary a lot by variety, and it changes how long a batch is worth saving versus using soon.

Clemson Cooperative Extension’s Home & Garden Information Center attributes most of that spread to skin thickness: thick-skinned varieties resist moisture loss and bruising far better than thin-skinned ones. McIntosh is a special case. University of Maine research cited by multiple extension sources notes that McIntosh produces unusually large amounts of ethylene as it ripens, which makes it difficult to store once that rise starts, so it’s worth using or processing before the thin-skinned, high-ethylene batches start to soften. If you grow or buy a mixed harvest, sort by variety before you sort by size: a box that’s half Gala and half Granny Smith will have you discarding the Gala in week three while the Granny Smith is still firm at month four.

Should you store apples in the fridge or a root cellar?

For a few weeks, the fridge crisper drawer is the simplest option and needs no setup. For months, a cold, humid space that isn’t a refrigerator works better because it holds more volume: an unheated basement, a garage that doesn’t freeze, or a true root cellar if you have one. Iowa State Extension notes that in an unheated storage area, apples need insulation against actual freezing, such as packing crates with hay or using an insulated chest, since a hard freeze turns the flesh mealy and brown once it thaws.

However you store them, two habits do more for keeping quality than any container choice:

• Wrap or separate individual apples. Wrapping each one loosely in paper (plain newsprint in black ink, not colored, or tissue paper) keeps fruit from touching, which matters because rot spreads fast between apples that are in contact with each other.
• Check regularly and remove culls. Inspect stored apples every week or two and pull out any with soft spots, bruises, or mold as soon as you see them. One rotting apple left in a box will take its neighbors down with it. Apples with bruises from the start shouldn’t go into long-term storage at all; use those first, in cooking or sauce.

Only store apples that are free of bruises, cuts, and insect damage. Damaged fruit breaks down fast and spreads decay to whatever is stored around it, so sorting before storage, not after, saves the rest of the batch.

Why do apples need to stay away from other produce?

Apples are one of the heaviest ethylene producers among common fruit, a group that also includes bananas, pears, and tomatoes. Ethylene is a plant hormone that signals nearby produce to ripen, which is why a bag of apples left next to leafy greens, broccoli, carrots, or berries in the fridge shortens their life, not the apples’. Our guide to storing food to prevent waste has a full chart of which produce produces ethylene and which is sensitive to it; apples sit firmly in the “keep separate” column; it also covers which foods belong on the counter versus in the fridge more generally. In practice, that means a dedicated crisper drawer, a separate box in the cellar, or at minimum their own perforated bag, away from anything you don’t want ripening faster.

How long do apples actually keep, and how do you know when they’re done?

Even stored well, apples are not indefinite. For how other refrigerated foods compare, see our reference chart of how long food lasts in the fridge. For apples specifically:

The test is the fruit, not the calendar: a shriveled skin means moisture loss, a soft or mealy texture means it’s past its best for fresh eating (but often still fine cooked), and any mold, brown soft patches, or a fermented smell means it should be composted rather than eaten. Cores and peelings from apples you do eat are good compost material too; see our guide to starting a compost pile if you’re not composting food scraps yet.

Can you freeze or dry apples for longer storage?

When a harvest or a bulk buy outlasts cold storage space, freezing and drying both turn a surplus into something shelf-stable.

Freezing. Peel, core, and slice apples, then treat them to stop browning: Purdue Extension’s method dissolves 1/2 teaspoon of ascorbic acid in a quart of 40-percent sugar syrup, or for a dry pack, sprinkles 1/2 teaspoon of ascorbic acid (dissolved in a little water) over sliced fruit mixed with sugar before freezing on a tray and bagging once solid. For applesauce, cook peeled, chopped apples with a little water and ascorbic acid until soft, then cool and freeze in flat, labeled containers, leaving headspace for expansion. Frozen apple slices and sauce keep their quality for about eight to twelve months in a freezer at 0°F (-18°C).

Drying. Penn State Extension and other land-grant food-preservation programs recommend slicing apples about 1/8 inch (3 mm) thick, with an optional dip in ascorbic acid or lemon juice to limit browning, then drying in a dehydrator around 125–140°F until the slices are leathery and no longer sticky. An oven works too, set to its lowest temperature with the door propped slightly, but takes two to three times longer and uses more energy. Dried apples should cool fully before going into an airtight container; they keep longest in the fridge or freezer rather than a cupboard.

Both methods trade a little texture for a lot of shelf life, and both are a better use of surplus apples than letting a full crisper drawer turn into a compost problem by default. Between cold storage for the apples you’ll eat fresh and freezing or drying for the rest, a typical home harvest or bulk purchase doesn’t need to go to waste before it’s gone.
