Bitter means that something is alkaline or basic.  Sour is acid.  Silver Oxide 
is
a base, and silver hydroxide spontaneously changes to silver oxide upon
standing.  Since all you have to start with are silver, oxygen and hydrogen, the
only likely canidate is silver oxide.

I would say you let it go too long or at too high a current.
