There is no word in the Bible called "grape juice".
The word used is "beverage" and context determine if it is alcoholic or not.
The reason the Passover supper that we call "the Lord's Supper" is not wine (one of the many reasons) is that Passover is considered the first day of the feast of unleavened bread and no yeast of any kind was allowed -- not even yeast used in making wine.
"The role of yeast in wine making is the most important element that distinguishes wine from grape juice. In the absence of oxygen, yeast converts the sugars of wine grapes into alcohol"
First of all, after fermentation the yeast has died off, the sugars needed to feed the yeast are eaten away by the yeast. The alcohol which is left does not allow the yeast to remain. As for Passover unleavened bread is bread made on the spot in haste, wine is a process which requires time. Wine was a staple for the Hebrews and was made in advance and would have been stored once turned to wine, and would be on hand. Grape juice does not have a long shelf life, and when pressed and stored goes bad quickly and has to be used within a day or two at most once pressed or extracted. Christ used WINE at the Last supper not grape juice, my family makes wine and knows the shelf life of grape juice.Christ drank wine in his life:
Jesus Testifies about John Luke:733-35
…33For John the Baptist came neither eating bread nor drinking wine, and you say, ‘He has a demon!’ 34
The Son of Man came eating and drinking, and you say, ‘Look at this glutton and drunkard, a friend of tax collectors and of sinners!’ 35But wisdom is vindicated by all her children.”…
At the wedding feast at Canaan Christ turned water into wine not grape juice.
John2:8-11
8 Then he told them, “Now draw some out and take it to the master of the banquet.”
They did so, 9 and the master of the banquet tasted the water that had been turned into wine. He did not realize where it had come from, though the servants who had drawn the water knew. Then he called the bridegroom aside 10 and said, “Everyone brings out the choice wine first and then the cheaper wine after the guests have had too much to drink; but you have saved the best till now.”
11 What Jesus did here in Cana of Galilee was the first of the signs through which he revealed his glory; and his disciples believed in him.
Why do you suppose Christ did this at the Wedding feast and last supper? This is the establishment of the Eucharist,
and is the table of the Lord, which we come to when we participate in and do in memory of Him.
Luke22:19
19
And He took the bread, gave thanks and broke it, and gave it to them, saying, “This is My body, given for you; do this in remembrance of Me.” 20In the same way, after supper He took the cup, saying, “This cup is the new covenant in My blood, which is poured out for you.…
Christ is truly present in this sacrificial memorial, this must be approached in faith.
John 6:52-54
Jesus the Bread of Life
…52At this, the Jews began to argue among themselves, “How can this man give us His flesh to eat?” 53
So Jesus said to them, “Truly, truly, I tell you, unless you eat the flesh and drink the blood of the Son of Man, you have no life in you. 54Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day.…
Any one who denies Christ is truly present in this sacrament of faith, denies Christ's words. Now, the times are dark and will grow even darker, there will come a time when the sacrifice is completely abolished:
Michael's Deliverance and the End Times Daniel 12:12
…11"From the time that the regular sacrifice is abolished and the abomination of desolation is set up, there will be 1,290 days. 12
"How blessed is he who keeps waiting and attains to the 1,335 days! 13"But as for you, go your way to the end; then you will enter into rest and rise again for your allotted portion at the end of the age."…
We see glimpses of this happening with the Papal decree of 1994 which was made formal in1998 with the removal of the Tabernacle from off the altar. All modernist RCC's have conformed. Some traditionalist have not. This will happen in our life times:When the abomination which makes desolate comes about, the heretical followers will set up the abomination, in churches and synagogues =unity of all religions under one man as god . Christianity will be illegal, and any public practice of the sacrificial offering of the Body and Blood of Christ will be abolished:

verb
verb:
abolish; 3rd person present:

abolishing
formally put an end to (a system, practice, or institution).What does this mean for the faithful of all denominations? You will eat bread in haste, in seclusion and hiding, like the first church and the first followers of Christ. All believers in faith know the Holy Spirit transforms the wine and bread. Priest and shepherds will not be around for many.The few that are against the Vatican will be helped by the Holy Spirit to persevere to the 1,335 days spoken in Daniel. So most of the faithful will have to preserve this sacrifice privately. The first Woe is at hand, World war and cosmic events. Pray! The revealing of the Man of Sin is upon us.
