I take young coconut water and culture the sugar out with water Kefir grains for a couple days I do several coconuts at a time ---
then I strain out the kefir starts and add
fresh lemon and lime juice & (at least one lemon or lime per coconut)
Stevia to taste
Cranberry concentrate for color and to help the kidneys :-)
Pomagranite and black cherry concentrate if I have them available
then I add 50% by volume purified water then
leave it set out for a while with a tight caped jar to get the fizz going and then refrigerate
it will keep for a good while
this is the best blood pressure medicine I have found
