Jesus did not serve fomented wine in the upper Room..
FACT IS HE DID NOT CALL IT WINE
His words were
Mat 26:28 For this is my blood of the new testament, which is shed for many for the remission of sins.
Mat 26:29 But I say unto you, I will not drink henceforth of this -->fruit of the vine,<<---
until that day when I drink it new with you in my Father's kingdom.
The blood of grapes was symbolic of the Blood of Jesus.
WHAT JESUS SAID WAS RECORDED IN THREE OF THE FOUR GOSPELS
Mat_26:29 But I say unto you, I will not drink henceforth of this -->fruit of the vine,<-- until that day when I drink it new with you in my Father's kingdom.
Mar_14:25 Verily I say unto you, I will drink no more of the
--> fruit of the vine,<--- until that day that I drink it new in the kingdom of God.
Luk_22:18 For I say unto you, I will not drink of -->the fruit of the vine,<-- until the kingdom of God shall come.
==>JESUS REFERRED TO HIMSELF AS THE VINE IN
Joh_15:4 ==> Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
AND HE MADE IT MORE SPECIFIC IN..SAID HE IS THE VINE..
Joh_15:5 ==>I am the vine, ye are the branches:<== He that abideth in me, and I in him, the same bringeth forth much fruit:
for without me ye can do nothing.
I can see your point....
However, I always considered Psalm 104
15 " And wine that maketh glad the heart of man, and oil to make his face to shine, and bread which strengtheneth man's heart."
as to being wine that is fermented.
The fruit of the "vine" in the cases you present is the grapevine.
And there is no reason to think that Jesus did not partake of fermented wine, as it was common in his time. From what I know, it was rather concentrated, and was diluted with water.
