How to Store Quince

As an Amazon Associate we earn from qualifying purchases.

Quince is a hard, aromatic fruit that is rarely eaten raw, which means most people store it for a few weeks before cooking it. How to store quince depends on the stage of ripeness at harvest, the temperature and humidity where it sits, and how carefully it is handled. Research on quince cold storage describes what happens over months at controlled temperatures. A gardening magazine gives practical guidance for home storage. This guide uses those sources, and it marks clearly where the sources do not give a home answer.

Quick answer

Harvest quince while it is still firm. Gardener’s World advises harvesting “just before they ripen” for the best storage results.
Store it somewhere frost-free, well-ventilated and out of direct sunlight. Gardener’s World gives this as the home storage condition.
Research storage at 0 to 2 degrees Celsius can keep quince for two to six months, but the controlled trials do not describe a home method.
Check the fruit often. Gardener’s World advises looking for rot and checking ripeness regularly.

How we chose

This guide relies on three sources: a research article on harvest stage and postharvest treatment of ‘Eşme’ quince, published through the International Society for Horticultural Science; a conference paper on ripening regulation during storage in quince, which reports storage at 0 or 2 degrees Celsius; and a Gardener’s World article on storing quince at home. The gardening magazine is a non-retail publication. The two research sources report controlled storage trials, so they are used for what they measured, not as home instructions. No extension or USDA page on quince storage was found, and the guide says so. Each source was opened on 2026-10-27, and the quoted sentences come from the fetched text. For a broader view of storing harvested produce, see how to store freshly harvested vegetables.

Pick quince at the right stage

Harvest stage affects how long the fruit keeps. Gardener’s World says the best results come from harvesting quince “when they’re still firm, just before they ripen.” The research supports this. The ‘Eşme’ trial found that late harvest reduces storage quality: “Fruit flesh firmness in non-treated and late harvested fruit was lower at the end of 6-months storage.” The same study reports that browning rises with maturity: “The browning index was reduced significantly with the application of 1-MCP, but increased as harvest maturity advanced.”

In practice, choose fruit that is firm and free of bruises, and avoid any that are already soft. Fruit that is picked too late and then bruised will spoil faster than firm fruit picked at the correct stage. The sources do not give a colour or size test for harvest, so use firmness as the main guide.

Choose the storage place

Gardener’s World gives the home storage rule in one line: “Make sure wherever you store them is frost-free, well-ventilated, away from direct sunlight.” Frost damages fruit, direct sun warms it, and poor air movement can hold moisture around it. A cool shed, a garage that stays above freezing, or a cool room works when it meets those three conditions.

Keep quince separate from fruit that you do not want to ripen quickly. The sources in this guide do not give a list of ethylene-producing fruit, so this step is a general kitchen rule rather than a verified claim. Spread the fruit so that it does not press against other fruit, since bruised areas spoil first.

Cold storage limits from research

Commercial research gives the clearest figures for how long quince keeps cold. The conference paper on ripening regulation says, “The fruit can be stored at 0 or 2 degrees C for two to six months.” It adds that storage can be extended further with controlled atmosphere, which is not a method for home storage, since it requires gas control equipment.

The ‘Eşme’ trial stored fruit at a closely related setting: “Treated and non-treated fruit were stored at 1°C and 90-95% relative humidity conditions for 6 months.” The trial also tested a shelf-life step at room conditions: the fruit was “kept at shelf life conditions (20±1°C and 55-65% relative humidity) for 7 days.”

The research is about controlled trials, not a home refrigerator. It shows the direction of change: cold, humid storage slows quality loss, while warmer conditions shorten the period before softening. The sources do not give a recommendation for a home refrigerator drawer, so this guide does not state a refrigerator time.

Watch for browning and softening

Flesh browning is the main storage problem named in the research. The conference paper states, “The formation of flesh browning is the most limiting factor in storage of quince fruit.” It is also the reason that the trial tested 1-MCP, a chemical treatment. Home storage does not include that treatment, so the main protection at home is to pick firm fruit at the correct stage and to keep it cool and ventilated.

Check the fruit regularly. Gardener’s World advises, “Check your quince every now and again, to keep an eye on their ripeness and make sure they aren’t rotting.” Remove any fruit that is soft or mouldy.

Gardener’s World says home-stored quince “can last for several weeks,” which gives a practical planning range for fruit kept under the conditions above. The figure is general and is not a controlled-trial result.

What we could not verify

This section lists what the sources do not establish. It is a limit on this guide, not a claim that the answer is known.

What the sources do not say

No extension or USDA source on quince storage was found. The guide relies on research trials and one gardening magazine.
No verified source gives a home refrigerator time for quince.
No verified source gives a freezing method or frozen storage time for quince.
No verified source gives a canning method, process time or sugar ratio for quince jelly, jam or paste. This guide does not give those steps. For any preserved product, follow a tested method from the USDA National Center for Home Food Preservation or a state extension office.
No verified source gives a shelf life for quince paste (membrillo).
The research trials used controlled rooms and controlled atmosphere. Their results describe those conditions, not a kitchen.

Frequently asked questions

How long does quince keep?

Gardener’s World says home-stored quince “can last for several weeks.” Research trials in controlled storage at 0 or 2 degrees Celsius report two to six months, but these are not home conditions.

Should quince be picked ripe or firm?

Firm. Gardener’s World advises harvesting when the fruit is still firm, just before it ripens, and the ‘Eşme’ trial found that late-harvested fruit had lower firmness after six months of storage.

Where should I keep quince at home?

Gardener’s World says to keep it frost-free, well-ventilated and away from direct sunlight.

What makes quince go bad in storage?

The research names flesh browning as the most limiting factor in storage. Gardener’s World advises checking the fruit regularly for rot and removing any that is soft or mouldy.

Can you freeze quince or use it for paste?

The sources in this guide do not give a verified freezing method or a shelf life for frozen quince, and they do not give a tested method for paste. For canned or shelf-stable products, follow tested guidance from the USDA National Center for Home Food Preservation or a state extension office.
