You are right, Jesus hated those Pharisaic formalities that prevented people from actual loving others. However Jesus did participate in other Jewish “formalities”. He celebrated the Passover, the festival of tents, he was presented at the temple, and so on.

To say Jesus believes all formalities are bad is not true.

For this partially question, what is wine, I don’t think it is preventing us from loving God and neighbor. I do think it is important because of the centrality of wine in the Gospels. T he miracle of the wedding feast at Cana, image of the vine and branches, and with the culmination of the last supper.
