resty, now I understand you aren’t a nutritionist or a vintner, but how long are grapes on the vine? A few weeks out of the year, perhaps? But let’s go so far as to say there are ripened grapes on the vine for a whole month, so maybe, just maybe, the people (before refrigeration) had fresh stomped grapejuice for a month out of every year. How long do you think you could keep grape juice in a warm climate before it turned rancid or fermented?
Seriously, try it. Set some grapejuice out on your kitchen counter for a month, then drink it.....I’m sure that’s what all the people in Biblical times did, they just drank old rank grapejuice (that hadn’t fermented) LOL
You are too, too funny dear.
