What kind of angels? Seraphim? Cherubim? Arch?
Makes a difference.
Well, cherubim, in the Bible, are usually angels guarding some form of the presence of God. There's one that guards the entrance to the Garden of Eden after humans are expelled, another associated with the ark of the covenant. And, of course, later they are connected with baby angels. Neither seems likely.
The archangels generally seem to be killing things, wrestling with things, being the highest order of angels.
Raphael does what might be called heralding in Paradise Lost, but he doesn't sing. And of course angels are involved in telling Mary what is happening to her, but also not by singing. I think that's just in Christmas carols.
The seraphim are the ones that circle the altar of God, singing Holy, Holy, Holy, so they are the best bet. I'm guessing, though, that that song gets monotonous (see Dudley Moore in Bedazzled), so if they were the ones who were singing, it might be a sign that the wine was monolithic and spoofed (I am tempted to say, like the Judeo-Christian god).
When wine sings for me in angelic tones, its usually the Vienna Boys Choir singing You Can't Always Get What You Want.
