Coconut water (also coconut juice) is the clear liquid inside coconuts (fruits of the coconut palm). In early development, it serves as a suspension for the endosperm of the coconut during the nuclear phase of development. As growth continues, the endosperm matures into its cellular phase and deposits into the rind of the coconut pulp. The liquid inside young coconuts is often preferred to the liquid of a ripened coconut. Coconut water from young green coconuts is also known specifically as buko juice in Philippine English.
Coconuts grow in tropical climates on trees scientifically known as Cocos nucifera, and are botanically considered a fruit.
Coconut water is the liquid found in the center of a young, green coconut. It helps nourish the fruit. As the coconut matures, which takes around 10–12 months, some of the liquid remains while the rest ripens into the solid white flesh known as coconut meat.
Coconut water typically comes from young coconuts about 6–7 months of age, though it’s also found in mature fruit. An average green coconut provides about 1/2–1 cup of coconut water.
Coconut water contains 94% water and very little fat. It should not be confused with coconut milk, which is made by adding water to grated coconut meat. Coconut milk contains about 50% water and is quite high in fat
