The iconic kiwi fruit is not just a single variety but a diverse group of cultivars, each with distinct characteristics that set them apart. The most common varieties found in stores are defined by their internal flesh color: green, gold, and the more recent red. Understanding these differences can help you appreciate their unique flavor profiles and nutritional benefits.
The Classic Green Kiwi
The green kiwi, particularly the Hayward variety, is the type most people are familiar with. Its appearance is defined by its fuzzy, brownish skin and a distinct oval shape.
- Flavor Profile: Green kiwis have a perfect balance of sweet and tangy, with a citrusy, vibrant flavor. They are often described as having a zesty kick.
- Texture: The green flesh is typically firmer and more fibrous than other varieties, with a satisfying bite. It has a larger core with numerous tiny black seeds.
- Nutritional Highlights: This variety is particularly rich in dietary fiber, which aids in digestion and can help lower cholesterol. It also contains the enzyme actinidin, which helps break down protein.
- Ripening: Green kiwis are often firmer when purchased and require a few days at room temperature to soften and ripen fully.
The Sweet Gold Kiwi
Golden kiwis, like the popular Zespri SunGold variety, offer a sweeter, less tart alternative to their green cousins. They are the result of natural breeding programs and feature a distinctly different look and taste.
- Flavor Profile: With tropical undertones reminiscent of mango and melon, gold kiwis are noticeably sweeter and less tangy. The flavor is smooth and fragrant.
- Texture: The skin of a golden kiwi is smooth and hairless, or only lightly fuzzy. Inside, the vibrant yellow or golden flesh is softer and has a smaller white core with fewer, smaller seeds.
- Nutritional Highlights: Golden kiwis contain significantly higher amounts of Vitamin C—sometimes nearly double that of green kiwis. They are also a good source of folate.
- Ripening: Gold kiwis are often ready to eat when purchased and become even sweeter as they soften. They also have a longer shelf life in the refrigerator than green kiwis.
The Emerging Red Kiwi
A newer innovation in the kiwifruit family is the red kiwi, which is now commercially available in some markets. This variety combines appealing aesthetics with a delicate flavor.
- Flavor Profile: Red kiwis are known for their sweet, berry-like taste with a slight tang. Many compare the flavor to a hint of raspberry.
- Appearance: With a striking red core surrounded by yellowish flesh, the red kiwi offers a visually stunning experience. It typically has smooth, thin skin.
- Characteristics: Because it is a newer variety, the industry is still learning the optimal growing conditions for red kiwis, but they have been well-received in market trials.
