What’s a Kiwi Berry? Kiwi Berries are a bite-sized, fuzz-less, sweet super-fruit that looks like a mini-kiwifruit. Kiwi Berries are a vine fruit the size of a Grape, have smooth skin and are a surprisingly delectable sweet ‘n tangy snack! You eat them whole – no cutting or peeling! They’re perfect for snacking when soft-ripe.
