At our last party one of Charlie’s friends brought two 5 liter mini-kegs of Warsteiner beer. We put the kegs in the fridge and promptly forgot about them.
“What a waste”, we thought. But then we tasted the first keg.
It seems that Charlie’s friend wasn’t being generous, he was unloading some really nasty beer on us.
I still have one of the kegs, untapped. I was going to throw it out but now I’m thinking this beer should be destroyed for the good of humanity.

Any suggestions?
