Decomposition of ethanol

Hi everyone! I was hoping some people could pitch in and help me with a little joke I had in mind...

I was wondering if there was some sort of safe-to-consume compound that could act as a sort of 'catalyst' (not necessarily in the literal sense) to breaking down ethanol in an alcoholic beverage to, say, acetic acid. The drink still has to be perfectly safe to drink (save for the potentially awful flavor) - remember this is a hypothetical joke, not a felony! Bonus points if it was almost undetectable (didn't change the flavor much) as I don't think parties involved would be incredibly impressed to find that their 'investment' was 'sabotaged'.

All suggestions and comments are welcome.

That is perfect! Thankyou!

... Though some chemical solutions wouldn't be bad either.
