The amount of micro plastic in each. The large one would be the purest taste, the can and small bottle would vary due to light degradation being less in the liner of the can. Can think of no other logical reason.

Types of plastic too. BPA from the can liner(usually), Polyethylene from the jug, wax from the paper carton.
