What basis do you have for calling it a Pharisee wedding? There is nothing in John’s account to indicate that any Pharisees were there. If it had lasted half a day, it isn’t likely they would have run short of wine.

Everything about it was Pharisee. Everything about Judea was Pharisee. The first of Yeshua’s Earthly missions was to demolish the false worship demanded by the Pharisees, and return his people to his Torah.
It was the event that Yeshua chose to demolish the Pharisees’ “washing of the hands” by despoiling their hand washing pots when he filled them with wine.
Each and every miracle that Yeshua did was purposed to demolish one of the Pharisees’ Takanot.
You seem to have an exaggerated vision of how much wine even a wealthy man, such as the groom must have been, might have available. The available land on which to grow grapes in Israel was always limited. The slopes were dry and rocky; only the river valley was arable land.
