Dana355,
This sound like an omen. You should make the sacrifice and drink it.
On the other hand, it may have had some residual sugar and wasn't quite finished. Or not gassed off good. I always leave my bottled wine to stand upright for several days to let the gasses escape in case I didn't do a good job de-gassing.
Maybe someone else will gesture a guess?

I assume that is CORKED for the several days? (New to This!)
