Aventinus is a deliciously dark full beer with sweet flavours and a very rich malty taste. Perfect for cooking ham with!
I'd put the presoaked ham in tinfoil, pour over some Aventinus, and even add mustard and pepper/spices to the mix. You could even make a glaze afterwards with a mix of a little beer, some brown sugar, mustard, pepper etc. Just make the glaze mixture and 20 mins before the end of cooking, open the foil and spoon on, leaving uncovered until ham is ready.
In fact, I might have ham myself tonight...!!
