There is a very simple explanation to your question. Let’s read Luke 22:14-18, “When the hour had come, He sat down, and the twelve apostles with Him. Then He said to them, ‘With fervent desire I have desired to eat this Passover with you before I suffer; for I say to you, I WILL NO LONG EAT OF IT UNTIL IT IS FULFILLED IN THE KINGDOM OF GOD.’ Then He took the cup, and gave thanks, and said, ‘Take this and divide it among yourselves; for I say to you, I WILL NOT DRINK OF THE FRUIT OF THE VINE UNTIL THE KINGDOM OF GOD COMES’” (NKJV).

The Lord Jesus was on His way to suffer on the cross as the “Passover Lamb.” Because of this He had a real desire to eat the Passover with them one more time. I want to emphasize this was NOT the “Last Supper” (which we will see in a few minutes) but the “Passover.” In saying He will not EAT or DRINK of the bread and wine He is simply saying, “I will not be celebrating the Passover with you until the kingdom of God is established on earth.” He was NOT saying He would not eat any bread or drink any wine until then, for after His resurrection He did indeed eat bread with two disciples in their home in Emmaus (see Luke 24:13-31, especially verse 30).

The Lord Jesus also drank wine again; in fact, He drank wine IMMEDIATELY after the Passover. We will now continue in our reading in Luke 22 by reading verses 19-20, “And He took bread, gave thanks and broke it, and gave it to them, saying, ‘This is My body which is given for you; do this in remembrance of Me.’ Likewise He also took the cup after supper, saying, ‘This cup is the new covenant in My blood, which is shed for you.” We see in this passage that the Lord used the bread and the wine that had been used in celebrating the Passover to institute the Lord’s Supper. The Passover reminded them of their deliverance from bondage in Egypt through the death of an innocent lamb and the shedding of blood. The Lord’s Supper would remind them of the deliverance He was about to accomplish by laying down His life (i.e. body) on the cross and by shedding His blood. The bread was a fitting SYMBOL of His body and the wine was a fitting SYMBOL of His blood.

I trust you have seen that the Lord still drank wine after the Passover and that His words regarding not drinking wine until the kingdom of God is set up on earth is in relation to the Passover and does not include drinking wine for other reasons. This teaches us a valuable lesson and that lesson is we must always consider the CONTEXT in which a verse is found in order to interpret its true meaning. (316.6) (DO)
