I have never had UCC but that sounds a lot like what cheap instant coffee tastes like to me. Initially I thought it might be an auto reaction to old break rooms when people were allowed to smoke so I associated instant coffee with cigarette smoke, but I had a cold brew in a bottle the other day and that same sensation happened.
