Kiwi Berries known as ‘cold hardy kiwi’ fruit, are the miniature cousins of the familiar fuzzy brown kiwi. They can be referred to as kiwi berries, kiwi grapes, or baby kiwis. The kiwi berry (Actinidia arguta) is thought to be a forerunner of its larger cousin the kiwifruit. Kiwiberries have an appealing sweet flavour with a fine and delicate tangy finish. Their taste has been described to be similar to that of kiwi fruit with overtones of strawberry, passion fruit, pineapple, feijoa or melon.
The growth in popularity of the kiwi berry is large due to it being recognised as a super food. Known as the queen of super-fruits, kiwi berries have an amazing nutrient profile. If you look at vitamin C, a 100g serving of kiwi berries has 20 times that of the same amount of apples, twice that of strawberries and three times that of raspberries. In addition kiwi berries vitamin E content is nearly twice that of avocado and 20 times that of strawberries. Couple this with their vitamin B8, or inositol, which is the highest in the world. I should point out recent studies indicate the lack of B8 may contributed to diabetes.
