Making coconut milk is not difficult. All you need is a blender, a cloth (old pillow cut into 18-inch squares is perfect), a large mixing bowl, and a concrete sidewalk or other concrete slab. First, take out the coconut water by poking the soft "eye". There's always one eye that is soft, and it can be opened with a pointy knife and then the hole enlarged with a bamboo chopstick. Shake some of the water into a glass, then rest the coconut on top of the glass until all the water has dripped out. This water is excellent and nutritious, and you can use it as part of the water in a later step of the recipe.
Second step: shell-busting - this is fun and kids will enjoy it: put the coconut in a plastic bag (ziplock or grocery), close the bag, and take it to your concrete slab. Throw the coconut up, about 8 feet, so it will land on the slab. It will break and the pieces will stay inside the bag. Repeat until all the pieces are manageable, 4 to 6 times usually does it. A lot of the meat will even detach itself from the shell. Return to your kitchen and finish removing the meat from the shell. Taste the meat, because some coconuts aren't fresh any more (when in doubt, throw it out).
Third step: blending. Rinse the meat and transfer to a blender. You should have about a cup of meat. Add 3 cups room-temperature water (less if you want coconut cream). Blend on high (I do it in a Vitamix, for 1 minute).
Fourth step: "milking the coconut". Line the bowl with the cloth, pour the milk in. Wash your hands thoroughly and rinse them well. This is a hands-on step, and again, kids love to do this. You'll get coconut milk on your hands, which is a wonderful moisturizer. Pick up the cloth by the corners and hold the four corners in one hand, then pick up the new corners that have formed in the middle of the square sides, so that you hold the cloth at 8 points. Twist the cloth to wring out the milk into the bowl. Voila!
I get about 4 cups coconut milk per coconut, which is a lot cheaper than store-bought, and tastes incredibly fresh and wonderful. I use the remaining meat to make coconut flour pancakes and other baked goods for the SCD/GAPS diet.
I don't know what the nutrition composition is for the home-made milk, but if you look up coconut nutrition facts you'll get a pretty good idea. Some of the components will remain in the flour, so it's not exactly that. I do know it's delicious, cheap, easy, and *no additives*! I suspect that a good portion of the minerals gets transferred to the milk, and note that it's a source of manganese, magnesium, selenium, zinc, copper, iron, potassium, Vitamin C, Folate , Thiamin, Pantothenic Acid. And some of the best protein available from any source, animal or vegetable.
It seems long as written above, but with the concrete-slab shell-busting method, it really is quite fast and easy.
