Where to Store Plums: Refrigerator or Counter

Plums stay fresh longer in the refrigerator, but only after they ripen

Store ripe plums in the refrigerator in a plastic bag or container on a shelf, not in the crisper drawer. They will keep for five to seven days at refrigerator temperature. Unripe plums should sit on the counter at room temperature until they yield slightly to gentle pressure and smell sweet — this takes two to five days depending on how firm they were when you bought them. Once they reach that point, move them to the refrigerator to stop the ripening process and extend their life.

The reason is simple: plums ripen through a chemical process that slows dramatically when cold. A ripe plum at room temperature will soften, lose flavor, and begin to ferment within a few days. The same plum in the refrigerator stays firm and tasty for more than a week. But a plum that is still hard and sour will not ripen in the cold — it will just sit there unchanged until you take it out again.

Key Takeaways

• Unripe plums belong on the counter; ripe plums belong in the refrigerator in a sealed bag or container.
• A plum is ripe when it gives slightly to a gentle squeeze and smells sweet, not when it looks a certain color.
• Refrigerated ripe plums last five to seven days; room-temperature ripe plums last two to three days.
• Do not store plums in the crisper drawer — use a regular shelf where air can circulate around the bag.
• Plums will not ripen in the refrigerator, so ripen them on the counter first.

How to tell if a plum is ripe

Color alone does not tell you whether a plum is ready to eat. A red plum can be hard and sour; a dark purple plum can be overripe and mushy. The real test is touch and smell. Hold the plum gently in your palm and press with your thumb — it should give a little, like a ripe peach, but not feel soft or dented. If it is rock-hard, it is not ready. If your thumb sinks in easily, it is past its peak.

Smell the stem end. A ripe plum has a sweet, fruity smell. An unripe plum has almost no smell, or smells green and vegetal. This is the fastest way to check a whole bag at the store. If most of them have no smell, they will need two to five days on the counter before they are worth eating.

Ripening plums on the counter

Place unripe plums in a single layer on a plate or in a bowl on the counter, away from direct sunlight. They ripen faster at room temperature — between 68 and 72 degrees Fahrenheit is ideal. Check them daily by pressing gently and smelling. Once they yield to pressure and smell sweet, move them to the refrigerator immediately.

If you need plums to ripen faster, place them in a paper bag with a banana or apple. These fruits release ethylene gas, which speeds ripening. Fold the bag loosely and check every 12 hours. Do not use a plastic bag for ripening — it traps moisture and can cause mold.

Storing ripe plums in the refrigerator

Once a plum is ripe, place it in a plastic bag or airtight container and put it on a regular refrigerator shelf — not the crisper drawer. The crisper is designed to hold moisture, which can make plums soft and encourage mold. A regular shelf with air circulation keeps them firmer and fresher. Seal the bag loosely so some air can move around the fruit.

Ripe plums stored this way will last five to seven days. After that, they begin to soften noticeably and lose flavor. If you see any soft spots or smell fermentation, remove that plum from the bag so it does not spoil the others.

What happens if you refrigerate unripe plums

An unripe plum placed directly in the refrigerator will not ripen — it will simply sit there, hard and sour, until you take it out. The cold slows the ripening process so much that it essentially stops. You can take an unripe plum out of the refrigerator and leave it on the counter, and it will eventually ripen, but you have wasted time and shelf space.

The exception is if you bought plums that are already starting to soften but you will not eat them for several days. In that case, refrigerating them while they are still slightly firm will slow their ripening and give you more time. But if they are completely hard, the refrigerator will not help.

Signs a plum has gone bad

A plum is past eating when it has deep soft spots that feel mushy, when the skin is split or leaking juice, or when it smells fermented or alcoholic. A small blemish or slight wrinkle on the skin does not mean the plum is bad — cut away the damaged spot and eat the rest. But if the whole fruit feels mushy or the smell is off, throw it away.

Mold can grow inside a plum even if the outside looks fine. If you cut one open and see gray or white fuzz, or if the flesh is brown and mushy, discard it. Plums stored in a sealed container with moisture are most at risk for mold, which is why a loose plastic bag on a regular shelf is better than a crisper drawer.

Freezing plums for later use

If you have ripe plums you will not eat within a week, you can freeze them. Wash and dry them, cut them in half, remove the pit, and place the halves on a baking sheet in the freezer for two to three hours until solid. Then transfer them to a freezer bag or container. Frozen plums will keep for up to three months.

Frozen plums work well in smoothies, baked goods, and cooked sauces, but they will not be good for eating fresh — the texture becomes mushy when they thaw. If you want to preserve fresh plums for eating later, refrigeration is your only real option, and you are limited to about a week.

Frequently Asked Questions

Can I store plums in the crisper drawer?

You can, but it is not ideal. The crisper traps moisture, which softens plums faster and can cause mold. A regular shelf in a loose plastic bag keeps them firmer and fresher for the full five to seven days.

How do I know if a plum is ripe if it is still green?

Some plum varieties are green even when ripe. Press gently — it should give a little. Smell the stem end — it should smell sweet and fruity. Color is not a reliable indicator across all varieties.

What if I bought plums that are already soft?

Put them in the refrigerator right away in a loose plastic bag. They will keep for two to four days. Eat them first, before the firmer plums you bought at the same time.

Do plums ripen faster in a paper bag or on the counter?

A paper bag with a banana or apple speeds ripening by trapping ethylene gas. On the open counter, they ripen more slowly but still reach peak ripeness in two to five days. Check bagged plums every 12 hours so you do not miss the window.

Can I eat a plum that is slightly wrinkled?

Yes. A light wrinkle on the skin means the plum is very ripe and may be softer inside, but it is still safe to eat. Cut away any soft spots. If the whole fruit feels mushy or smells fermented, throw it away.
