I think I see the source of your difficulty here. You don't think Catholics realize that the wine used for the Eucharist is "the fruit of the vine."

In fact, these are the very words used in the Canon of the Mass, for example, Eucharistic Prayer IV:

In a similar way, taking the chalice filled with the fruit of the vine, he gave thanks, and gave the chalice to his disciples, saying:

TAKE THIS, ALL OF YOU, AND DRINK FROM IT: FOR THIS IS THE CHALICE OF MY BLOOD, THE BLOOD OF THE NEW AND ETERNAL COVENANT; WHICH WILL BE POURED OUT FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS IN MEMORY OF ME.

Jesus and the Apostles certainly must have drunk of the other cups of Passover wine during the Last Supper, before the consecration of what He said is "the chalice of my Blood." It does not follow that he had partaken of the consecrated wine, His blood, which he gave his Apostles. The text doesn't say that.

This was His last meal before His death. The time would be short. This is why He said "But I say to you that I shall not drink again from this fruit of the vine until the day in which I shall drink it with you new in the Kingdom of my Father.”

This meal was His last drinking of the Passover wine before His death.

Notice how your mystery religion makes subtle changes to dupe the foolish who will not read what the Bible ctually says? And any catholic could fix stupid by reading the actual texts, but apparently they prefer the deception because it is familiar. What a brilliant coup satan has fabricated with Catholicism.
