Kiwifruit belongs to the Actinidiaceae family. There are two main varieties of Kiwi: green and yellow (or gold); both have a brown skin covered with light down. The pulp in both varieties has a central white part surrounded by edible seeds. The two varieties differ mainly in their sweetness as the kiwi gold is very sweet compared to the slightly more acid green one.
Originally from southern China, it was considered a delicious fruit already by the Chinese emperors. In the twentieth century it spread widely in New Zealand where the kiwi is grown intensively; the current name of the fruit derives from the bird symbol of this nation.
