In this article, we will delve into the intriguing world of kiwis and explore why this otherwise vibrant and juicy fruit possesses a distinctively bitter taste.

From its unique composition to the environmental factors affecting its flavor, we will unravel the mystery behind why kiwi is so bitter.

Join us on this flavorful journey as we uncover the secrets of one of nature’s most intriguing fruits.

Is Kiwi sour or bitter?

Why Does Kiwi Taste Sour

Kiwi fruit is typically described as sweet and tangy rather than sour or bitter. It has a refreshing flavor with a hint of tartness.

The flesh of a ripe kiwi is usually sweet, while the skin is slightly tart.

Overall, the taste of kiwi can vary depending on its ripeness and personal preference, but it is generally considered more sweet than sour or bitter.

Why Kiwi is So Bitter?

Kiwi is primarily known for its tangy and slightly sweet taste, but occasionally, you may come across a kiwi that is disappointingly bitter.

There are several reasons why this bitterness may occur. Firstly, the level of ripeness plays a significant role.

If a kiwi is not fully ripe, it tends to be more acidic and less sweet, resulting in a bitter flavor.

Additionally, certain kiwi varieties naturally possess a higher level of acidity, leading to increased bitterness.

Another factor that can contribute to bitterness is improper storage. Kiwis are sensitive fruits that should be stored at room temperature until they ripen.

If they are stored in cold temperatures, such as a refrigerator, their flavor can be negatively affected, resulting in a bitter taste.

Why is My Kiwi Not Sweet?

If you find that your kiwi lacks sweetness, there are a few possible explanations. Firstly, as mentioned earlier, the level of ripeness is crucial.

Kiwis that are harvested prematurely may not have had enough time to develop their natural sugars fully, resulting in a less sweet taste.

Furthermore, environmental factors and growing conditions can impact the sweetness of kiwis.

Factors such as soil composition, sunlight exposure, and temperature fluctuations can affect the fruit’s sugar content.

Additionally, certain kiwi varieties inherently have a lower sugar content, leading to a milder sweetness.

Why is Kiwi Bitter with Milk?

Many people enjoy adding kiwi slices to their cereal, yogurt, or smoothies. However, some individuals have noticed that when they consume kiwi in conjunction with milk or dairy products, a bitter aftertaste occurs.

This phenomenon is due to an enzyme called actinidain present in kiwis. Actinidain breaks down proteins, including the proteins found in milk, resulting in a bitter flavor when combined.

To avoid this bitter taste, it is recommended to consume kiwi and milk separately or with a gap in between.

Kiwi, at its best, offers a delightful combination of sweet and tangy flavors.

When perfectly ripe, it has a refreshing sweetness reminiscent of a mix between strawberries and melons.

The fruit’s acidity provides a pleasant tartness that balances out the sweetness, resulting in a unique and enjoyable taste experience.

The juicy and succulent texture of the flesh adds to the overall appeal of kiwi, making it a popular choice among fruit enthusiasts.

How to Make Kiwi Taste Good?

If you find the taste of kiwi to be too sour or bitter for your liking, there are several ways to enhance its flavor.

Firstly, ensure that you choose ripe kiwis by gently pressing them. Ripe kiwis should yield slightly to pressure without being too soft.

Another method to improve the taste of kiwi is by pairing it with other fruits.

The natural sweetness of berries, bananas, or oranges can complement the tanginess of kiwi and create a more balanced flavor profile.

Additionally, blending kiwi into a smoothie with a hint of honey or maple syrup can add sweetness and mask any bitterness.

Lastly, consider incorporating kiwi into savory dishes or salads.

The combination of kiwi’s tartness with ingredients like avocado, cucumber, or citrusy dressings can create a delicious balance of flavors.


Kiwi, with its tangy and slightly sweet taste, is a delightful fruit that can be enjoyed in various ways.

While some kiwis may occasionally exhibit bitterness, understanding the factors that contribute to this taste can help you choose and store your kiwis more wisely.

By selecting ripe fruits, pairing kiwi with other flavors, and exploring new culinary combinations, you can truly appreciate the unique and refreshing taste of this wonderful fruit.

So go ahead, indulge in the vibrant flavors of kiwi, and let your taste buds dance with delight.
