A self-contained, consumer-ready product from a coconut that has a seed-case, a layer of coconut meat inside of the seed-case, and an internal cavity containing sterile coconut water, in a condition that is ready for a consumer to access and remove the sterile water within the coconut, and a method for providing such a product. One method comprises forming an aperture that extends through the seed-case of the coconut but does not extend through the layer of coconut meat; forming a coconut pre-product in a first location, by affixing to the apertured coconut a closure member that is adapted to close the aperture and to be easily removed by a consumer in a second location different from the first location; and providing a self-contained, consumer-ready coconut product, by associating, with the coconut pre-product, a pre-selected plunger member that includes an elongated lance member that the consumer slides within the aperture after removal of the closure member in the second location and penetrates through the layer of coconut meat and into the internal cavity containing the sterile water.
