This seems like a XKCD / Randall Munroe “What if” kind of question. I.e., how long would a person survive if all of the water inside them was turned into wine?
A quick search suggests that blood is 80% water. Turning that into wine at a weak concentration of 5.5% results in around at 14.5% BAC which is over 10 times greater than the highest ever recorded, so it would be certainly lethal.
Pretty much immediately. You wouldn’t even know it.
Acidic pH like wine denatures proteins. It would destroy you on the cellular level, basic cell functions would cease to work. You could say it would stop your breathing or cause an instant heart attack, but it would be more like as if it fried your brain and heart like an egg in an instant.
I have a different question. How much wine extract can i add to the water in my body to be able to correctly state i exist out of 80% wine and still live.
To be specific, it’d likely immediately fuck up the electrical signals in the brain, thus killing the brain.
