this may sound odd..maybe its just me, but my gym in high school had juices in cans...like orange juice and such. well, when you put stuff into a can, you get a sort of metallic taste to the liquid, and the orange juice always tasted "metallic"...and this was the same case...
Actually, I know exactly what your referring to. I prefer soft drinks in plastic bottles because cans add this after flavor. It is worse in juices. We first had a Minuet Maid machine that had different juices in my middle school then they switch contracts and got Ocean Spray. Both had a metallic taste to it.
