Kiwi fruits are sweet, tangy, juicy, and slightly soft when they’re perfectly ripe. But if you picked some hard kiwi fruits at the store or from your own tree, you might be wondering what you can do to get them to ripen at home. Luckily, kiwi fruits continue to soften and sweeten up when you simply leave them on your counter at room temperature! In this article, we’ll go over how to ripen kiwi fruits , how to tell if they’re ripe , and how to store them in the fridge or freezer so they last for longer, all with the help of personal chef Markeicha Dulaney and the culinary experts at Marrow Private Chefs. Keep reading to find out more!
What is the fastest way to ripen kiwi fruits?
Place unripe kiwi fruits in a paper bag with a banana or apple. These fruits produce ethylene gas, which tells the kiwis to ripen. Simply leave the bag on your kitchen counter at room temperature, keeping it away from light or heat. Most firm kiwi fruits will ripen in 1 to 2 days.
Steps
Ripening Kiwi Fruits
-
Set the kiwis you want to ripen on the counter at room temperature. Kiwi fruit continues to ripen after it’s picked—if you bought some firm, unripe fruits, they’ll soften and sweeten up at home. Just place the kiwis in a bowl on your countertop and keep them away from direct sunlight and heat, as this can cause them to rot quickly or get discolored. [1] X Research source
- How long does it take the kiwis to ripen? Most firm kiwi fruits will ripen on the counter in 3 to 5 days if stored at room temperature.
- Most kiwi fruits that you find in the grocery store, like the green and golden flesh varieties, ripen perfectly fine off the vine.
- If you're growing your own kiwi fruit plant , check the variety you have to determine whether you should leave your fruit on the vine until it's ripe or harvest it while it's hard.

To speed up ripening, place the kiwis in a paper bag with a banana or apple. The quickest way to ripen a firm kiwi fruit is to store it near fruits that produce ethylene gas, like bananas, apples, and pears. This exposes the kiwis to more ethylene, which tells them to ripen faster. Simply place the kiwis in a paper bag with the other fruits and keep them on your counter at room temperature.

- Keep the bag out of direct sunlight and away from heat sources, as this can cause the fruits to rot quickly.
- Do not place the kiwi in a plastic bag. This can reduce air flow and trap moisture, causing the fruits to rot and grow mold.
How to Tell If Kiwi Fruits Are Ripe
-
Press the kiwi fruit lightly to see if it has a little give. According to Dulaney, the best way to tell if a kiwi fruit is ripe is to give it a gentle squeeze with your thumb. If the kiwi is mostly firm with a little give and softness, it’s perfectly ripe.
- Avoid kiwi fruits that are very soft or mushy, advises Marrow Private Chefs, as this is a sign that they’re overripe and will go bad quickly.
- Remember, if you pick a kiwi that’s very firm and unripe, it’ll soften and sweeten up if you leave it on your counter at room temperature.
-
2Smell the kiwi for a sweet, fruity scent. When kiwi fruits ripen, they have a noticeable and pleasant fruity smell. If the scent is very faint or nonexistent, the fruit is probably unripe. And if the kiwis smell fermented, sickly sweet, or slightly sour, they’re most likely overripe and starting to rot. [4] X Research source
-
Make sure the outside of the kiwi fruit is unblemished. Look for a kiwi fruit that doesn't have any dark spots, bruises, mushy areas, or tears in the skin. The fruit should be plump and round without any wrinkles, flat spots, or sunken areas. [5] X Research source
- Most kiwi fruit varieties that you find in the store have brown, fuzzy skin. However, there are some varieties that have red or green skin.
-
Check that the seeds are black. If you have a lot of fruit to spare, cut a kiwi open and look at the seeds. A kiwi is unlikely to ripen if its seeds are still green or yellow—the seeds must be black. Black seeds indicate the kiwi has enough sugar to ripen properly. [6] X Research source
-
Eat the ripe kiwis within 1 to 2 days. Make sure to eat the kiwi fruit when they're at their peak ripeness, or within about 1 to 2 days when left on your counter. Because kiwis continue to ripen at room temperature, they can get overripe and start to rot quickly.

Tips
- Kiwi fruits are good sources of vitamins and minerals, including vitamins C and E, potassium, magnesium, and copper. Kiwi fruits have few calories, are high in fiber, and contain no fat or sodium.

- Kiwis must be exposed to ethylene gas after they’re picked to start the initial ripening. If the growers and shippers don't begin to ripen the fruit, the starches aren't converted to sugars quickly enough, and the fruit shrivels.Thanks
