Navel raw orange juice takes some getting used to… I could see this having a bit of water added or something. But this is the same flavor I experienced in Southern California when I drank Evolution Orange Juice for 17 days.
Valencia has the tanginer, tartier, snappy sweet taste to it. It’s much easier to down. But it also gives you a sharp acid burn if you drink it too fast. Navel not so.
Also, the organic Navel oranges are nearly the size of grapefruits while the conventionals are only as large as valencias.
This fast is going to be on conventional juice. It should be interesting.
