Kiwi berries are small, bite-sized fruits that resemble a fusion of kiwifruit, grapes, and kumquats. They are a variety of the hardy kiwi, or Actinidia arguta, which is a perennial vine native to Japan, Korea, Northern China, and the Russian Far East. Unlike most other species of the genus, kiwi berries produce a small kiwifruit without the hair-like fiber covering the outside. The fruit is also referred to as the arctic kiwi, baby kiwi, cocktail kiwi, dessert kiwi, grape kiwi, hardy kiwifruit, northern kiwi, Siberian gooseberry, or Siberian kiwi. Kiwi berries have a leathery, smooth, green skin that is edible and does not require peeling, unlike kiwifruit. They are often sweeter than kiwifruit and can be eaten whole. Kiwi berries are rich in vitamins C and E, fiber, magnesium, potassium, and antioxidants. They can be enjoyed as a snack, added to fruit salads, used as a garnish for cocktails, or made into jam. Kiwi berries are usually found in grocery stores such as Trader Joes and Costco.
