Coconut water (buko juice, in the Philippines) is the liquid inside young coconuts. It’s watery and only subtly coconut flavored–sort of sweet and grassy, notes StriperGuy–and nothing like the sweet, oily water found in mature coconuts.
Young coconut juice can be used as a sport drink or a simple beverage. It’s high in potassium, calcium and magnesium. And you can find it in Asian or Latin markets, in bottles or cans.
You can order a good brand at Amazon.
