Storage chart
| Pantry | Fridge | Freezer |
|---|---|---|
| Until ripe | 3 weeks | Not recommended |
Fridge at 40°F (4°C) or colder, freezer at 0°F (−18°C). Freezer times are for best quality; food kept frozen stays safe indefinitely.
Storage tips
- Ripe is when this item is tender, fully developed and ready to eat.
- Timeline for refrigerator applies to ripe fruit.
Keep it longer
Keep most produce whole and unwashed until you use it; washing adds moisture that speeds spoilage. Store fruit that gives off ethylene (apples, bananas, avocados) away from leafy greens.

How long do kumquats last in the fridge?
3 weeks in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze kumquats?

Until ripe in a cool, dry pantry.
How can I tell if kumquats have gone bad?
Throw them out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
