Isaiah 25 depicts a feast:
Mark 14:25
It is the physical/horizontal drink at the last supper which they have just drunk.
What is meant by drinking it 'new'?
The new drink is the heavenly/verticle counterpart of the horizontal fruit of the vine.
What is 'that day'?
It refers to the day of the heavenly banquet of the marriage supper of the Lamb.
Jesus knew that the fruit of the vine on that Passover night was his last celebrative drink before he died. Jesus bound himself by a divine promise/sacrifice not to drink the equivalent heavenly wine until we celebrate the marriage supper of the Lamb in the consummated kingdom of God.
The enemies of Paul bind themselves not to eat or drink in Acts 23:12 in order to show that they mean serious business:
Death is no more. It is a heavenly feast. A similar feast is described in Revelation 19:6 On this mountain the Lord Almighty will prepare
a feast of rich food for all peoples,
a banquet of aged wine—
the best of meats and the finest of wines.
7On this mountain he will destroy
the shroud that enfolds all peoples,
the sheet that covers all nations;
8he will swallow up death forever.
The Sovereign Lord will wipe away the tears from all faces;
he will remove his people’s disgrace from all the earth.
Luke 14:15 talks about the feast in the kingdom of God:6 Then I heard what seemed to be the voice of a great multitude, like the roar of many waters and like the sound of mighty peals of thunder, crying out,
“Hallelujah! For the Lord our God the Almighty reigns. 7 Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready; 8 it was granted her to clothe herself with fine linen, bright and pure”— for the fine linen is the righteous deeds of the saints.
9 And the angel said to me, “Write this: Blessed are those who are invited to the marriage supper of the Lamb.” And he said to me, “These are the true words of God.”
Then Jesus proceeds to tell them the parable of the Great Banquet. This theme of a heavenly feast runs through the OT and the NT.When one of those at the table with him heard this, he said to Jesus, "Blessed is the one who will eat at the feast in the kingdom of God."
Mark 14:25
What is the fruit of the vine?Truly I tell you, I will never again drink of the fruit of the vine until that day when I drink it new in the kingdom of God.
It is the physical/horizontal drink at the last supper which they have just drunk.

The new drink is the heavenly/verticle counterpart of the horizontal fruit of the vine.

The enemies of Paul bind themselves not to eat or drink in Acts 23:12 in order to show that they mean serious business:
Jesus does not swear an oath but simply says "Amen, I tell you". Certainly, Jesus means it. It will happen.The next morning some Jews formed a conspiracy and bound themselves with an oath not to eat or drink until they had killed Paul.
