Why Does Kiwi Taste Sour?

Kiwis have a natural acidity that gives them their characteristic sour taste. This acidity comes from the presence of organic acids, primarily citric acid and malic acid, in the fruit.

These acids contribute to the tanginess and zingy flavor that many people associate with kiwis.

The levels of acidity can vary depending on the variety, ripeness, and growing conditions of the fruit.

What Makes Kiwifruit Sour?

The sourness of kiwifruit can be attributed to several factors. Firstly, the organic acids present in kiwis, such as citric acid and malic acid, contribute to the overall sour taste.

These acids are essential for the fruit’s metabolism and play a role in its flavor profile. Additionally, kiwis contain enzymes called actinidain, which break down proteins and further enhance the sourness.

Furthermore, the ripeness of a kiwi affects its sourness. As the fruit ripens, the concentration of sugars increases while the acidity decreases, resulting in a sweeter taste.

So, if you prefer a less sour flavor, choosing a ripe kiwi might be more suitable for your palate.

Are Kiwis Supposed to Be Sour?

Yes, kiwis are naturally supposed to have a sour taste. In fact, the sourness is one of the defining characteristics of this fruit.

The balance between sweetness and sourness varies among different cultivars and stages of ripeness, but a certain level of tartness is expected in all varieties of kiwis.

Can You Eat Sour Kiwi?

Absolutely! While some people may find the sourness of kiwi too intense, others enjoy the tangy flavor.

Sour kiwis are safe to eat and provide various health benefits. Kiwis are rich in vitamin C, vitamin K, fiber, and antioxidants, making them a nutritious addition to your diet.

However, if the sourness is overpowering for your taste buds, there are ways to make kiwi less sour.

How Do You Make Kiwi Less Sour?

If you find the sourness of kiwi too strong, there are a few tricks you can try to make it less sour:

Ripen the kiwi: Allowing the kiwi to fully ripen will increase the sugar content and decrease the overall acidity, resulting in a sweeter taste. You can leave the kiwi at room temperature until it becomes soft to the touch.

Pair it with sweeter ingredients: Combining kiwi with sweeter fruits or ingredients can help balance the sourness. Add slices of ripe banana or berries to a kiwi fruit salad for a delightful blend of flavors.

Sprinkle a pinch of sugar: If you prefer a quick fix, you can sprinkle a small amount of sugar over sliced kiwi to help counteract the sour taste. This method is especially useful when using less ripe kiwis.

Blend it into a smoothie: Blending kiwi with other fruits, yogurt, or a sweetener of your choice can mellow out the sourness and create a refreshing and balanced beverage.

Experiment with these techniques to find a flavor profile that suits your preferences.

How Do You Know if Kiwi is Spoiled?

Determining if a kiwi is spoiled is crucial for your health and enjoyment. Here are a few signs that indicate a kiwi may be spoiled:

Mold or excessive softness: If you notice mold growth on the skin or the fruit feels overly soft and mushy, it’s best to discard it. These are common indicators of spoilage.

Off-putting odor: A strong, unpleasant odor coming from the kiwi is a clear sign that it has gone bad. Fresh kiwis have a distinct, pleasant aroma.

Discoloration or wrinkling: Kiwis that have turned brown, shriveled, or have an unusual discoloration should be avoided. These changes in appearance often accompany spoilage.

Sour or off-taste: While kiwis are naturally sour, if the taste becomes overwhelmingly acidic, bitter, or off, it’s a sign of spoilage. Trust your senses when assessing the taste of a kiwi.

By paying attention to these indicators, you can ensure that you consume fresh and delicious kiwis while avoiding any potential health risks.


Kiwifruit is renowned for its sour taste, which stems from the organic acids present in the fruit.

While the sourness of kiwis may not appeal to everyone, it is an inherent characteristic of this delightful fruit.

Fortunately, there are ways to make kiwi less sour by ripening it, pairing it with sweeter ingredients, adding a touch of sugar, or incorporating it into a smoothie.

However, if a kiwi exhibits signs of spoilage such as mold, excessive softness, off-putting odor, discoloration, or an unpleasant taste, it’s best to discard it to ensure your well-being.
