A young coconut, also known as a green coconut, is the immature fruit of the coconut palm tree, Cocos nucifera. It is typically harvested when it is about six to seven months old. The outer shell is green or yellowish, and the inner flesh is soft and jelly-like, while the liquid inside is known as coconut water. Young coconuts are popular for their refreshing taste and hydrating properties. The coconut water is low in calories and rich in electrolytes, making it a natural sports drink. The soft flesh can be eaten with a spoon and is often used in desserts and smoothies.
