Taste a little strange, but also Apple Juice browning,!!!
Yes, but you said, "it's not good." the juice of the juice suggests that several apples are already there. You can add some sweeter fruit than apple
Should be able to drink, I have done before
That's the iron in the apple. It's oxidized. Of course, you can drink it, but you don't drink it for the sake of enjoyment. It's wrong and ugly. Don't drink it. Things through the stomach, not necessarily not waste, and directly throw away is not the same, want to open up a little.
