Matthew, Mark and Luke all record Jesus saying he will not drink wine until God's kingdom has been restored; Matthew 26:29, Mark 14:25, Luke 22:18. Scripture records Jesus eating with his disciples; Luke 24:42-43, Acts 1:4. Scripture does not record when the early church started partaking of the Lord's Supper, but according to Matthew, Mark and Luke, Jesus could not have been a part of it if they did it in the first 40 days after Jesus rose.
While scripture says Jesus performed many signs in the 40 days after he rose from the dead, I don't think Jesus was constantly in the presence of the disciples in the time. Scripture says Jesus appeared and disappeared. While he did eat on occasion, I don't think he had to eat and drink. If Jesus had to drink, surely the disciples would have drank wine in 40 days and if Jesus was present, it would have been customary for him to also drink wine.
