If you've done it right, yes you'll be totally fine. And if you've done it wrong, maybe you'll die.
Maybe only have a tiny bit as a test. Like a few sips. And if in an hour you feel fine, maybe half a glass, then a glass and then you should know ur fine.
... But this is only a hypothesis. I dunno if it wont just kill you all at once, regardless of the amount of consumption.
Well, that depends
Yes of course if you know how to make it.
it can be if you make it properly
