To determine if a kumquat is ripe, check for a bright orange color with no green patches. It should feel slightly soft to the touch, similar in size to a large olive, and ideally be in season from late fall to early spring.

How To Tell If A Kumquat Is Ripe

Kumquats are unique in the citrus family. While larger citrus fruits give clear signs of ripeness, kumquats are a bit more mysterious.


A ripe kumquat will have a bright, vivid orange hue. Any green patches or an overall dull appearance can indicate that the fruit isn’t fully ripe yet.


Gently press the kumquat between your fingers. It should feel slightly soft but not mushy. A very hard kumquat isn’t ripe.


Generally, a mature kumquat is about the size of a large olive or grape. Anything significantly smaller might not be mature enough.


Kumquats are typically in season from late fall to early spring. Purchasing them during this time increases your chances of getting a ripe fruit.

How To Harvest Kumquats

Kumquats, the bite-sized citrus delights, require a keen eye and gentle touch when it’s time to harvest. Let’s explore the ideal timeframe and techniques for plucking these fruits at their prime.


The best period to harvest kumquats spans from late fall to early spring. Keep a close eye on the fruit’s color, which should shift from green to bright, radiant orange, signaling its ripeness.

For a more hands-on approach, conduct a taste test: a ripe kumquat boasts a sweet skin contrasted by a slightly tart flesh.


Arm yourself with sharp, sterilized pruning shears or scissors for a clean cut. Approach the kumquat with care, holding the fruit in one hand and using the shears with the other. Cut just above the fruit, ensuring a tiny portion of the stem remains attached to prevent damage.

For optimal results, harvest during the cooler morning hours, which not only minimizes stress on the tree but also helps in prolonging the fruit’s freshness post-harvest.

How To Tell If Kumquats Are Bad

Kumquats, like all fruits, have a shelf life. To ensure you’re enjoying them at their best, it’s essential to recognize the signs of spoilage. Here’s how to tell if Kumquats have gone bad:

  1. Texture: Good kumquats have a firm texture. If they feel mushy, overly soft, or have started to wrinkle significantly, they’re past their prime.
  2. Appearance: Check for any discolorations or dark spots on the skin, which can indicate decay or mold. Mold can appear as white, green, or black fuzzy patches.
  3. Odor: Spoiled kumquats might have an off-putting or sour smell, different from their usual fragrant citrus aroma.
  4. Taste: While a quick visual and olfactory check can be informative, tasting is definitive. If the kumquat tastes off, overly fermented, or just not right, it’s best not to consume it.
  5. Mold Inside: Sometimes, mold can develop inside the fruit even if the exterior looks fine. If the inside has any mold or an abnormal appearance, discard the kumquat.

Always trust your senses when evaluating any food item. If in doubt, it’s safer to discard questionable kumquats rather than risk consuming spoiled fruit.

How To Store Kumquats

Kumquats, with their tangy sweetness, are treasures you’d want to savor for as long as possible. Discover the best ways to store these citrus gems to keep them fresh and flavorful.

For immediate consumption within a week, place kumquats in a cool, dry spot away from direct sunlight. This helps retain their freshness while keeping them at hand for snacking or culinary use.

Extended Freshness

To prolong the fruit’s life, store kumquats in the refrigerator inside a breathable plastic or mesh bag. This method can keep them fresh for up to two weeks, ensuring they remain juicy and flavorful.

Freezing for Long-Term Storage

Once frozen, transfer them to a freezer bag, pushing out as much air as possible. This method allows you to enjoy kumquats for several months.
