they offered Jesus wine mixed with a bitter drug [i.e., for the purpose of dulling the pain of crucifixion. Mark 15:23 calls it "myrrh"], but when He tasted it He refused to drink it.

The soldiers also mocked Him; they came to Him, offering Him sour wine [to drink],

Now Jesus knew that everything had been completed [i.e., relating to His crucifixion], so then He said, in order to fulfill Scripture [Psa. 69:21], "I am thirsty."

But

Truly I tell you, I will not drink of this fruit of the vine [i.e., grape juice] any more until that day when I will drink it again [i.e., figuratively] in the kingdom of God."

And the disciples did [just] as Jesus had asked them, and they made preparations for the Passover meal.

for I tell you, I will not drink this fruit of the vine [i.e., grape juice] from now on until [I do, figuratively, when] the kingdom of God has come."

Then one of the soldiers ran and filled a sponge full of sour wine, put it on a stick and gave it to Him to drink, saying, "Let him alone; let us see if Elijah comes to take him down [from the cross]."
