I think it's about a relationship, where two people are in love, but one changes in a different direction, and how things can't be the same anymore. Things were happier before she changed, but there was no going back because things like that happen. The structure between them both didn't fit anymore, and their building broke.
They used to have water, and it changed to wine, which they weren't happy with.
But the whole setting of this song is sad, and I think the person talking was sad and heartbroken because he misses what things used to be like, and helpless because it couldn't ever be like that again. Water can turn to wine, but water can't turn back to wine.
