Why No Wine?

Out of curiosity, I want to hear what everyone’s been told to justify why Jesus drank wine but it’s not allowed anymore. I was told as a teenager it’s because back then it was grape juice not actually wine. I remember realizing on my mission that Jesus drinking grape juice was a ridiculous cop out. I don’t remember how I justified it after that (I’ve been out of the church for a while) so I’m curious what everyone else was told to make it make sense.
