“The word got out that Jesus was allegedly a glutton and a “winebibber.””
That’s what Jesus’ enemies said of him, wrongly.
As this criticism came largely from Pharisees, who were copacetic with alcohol induced jollies in religious contexts (Purim, for example, came with a tradition that you should get so drunk you couldn’t tell cursing the enemy from blessing the hero) I think it was based not on the fact that Jesus was jolly at banquets but that He was doing it with the “wrong people,” people who were notorious for things so bad that the Pharisees would not give them the time of day. Jesus had none of that narrow minded finickiness, of course, and was bent on saving souls.
