All I can say is that good wine is wine from the best grapes, and aged for the proper amount of time. For the master of the feast to call it good wine, it had to contain alcohol. Grape juice would not cut it at a wedding feast during this era.
Jeremiah 13:13
then say to them, ‘Thus says the Lord, “Behold I am about to fill all the inhabitants of this land—the kings that sit for David on his throne, the priests, the prophets and all the inhabitants of Jerusalem—with drunkenness!
Jeremiah 51:39
“When they become heated up, I will serve them their banquet And make them drunk, that they may become jubilant And may sleep a perpetual sleep And not wake up,” declares the Lord.
Isaiah 24:20
The earth reels to and fro like a drunkard And it totters like a shack, For its transgression is heavy upon it, And it will fall, never to rise again.
There are many references to becoming drunk, several that say something similar to "but not with wine", but the symbolism stands, imo.
