Why McDonald's Coke Tastes Different

McDonald's Coca-Cola is especially delicious due to a conglomeration of small factors and a few aspects particular to the brand that sets its Coke apart.

Moreover, McDonald's uses a concentrated syrup and water ratio to maintain flavor even as the ice melts. Their straws are also, so you get more Coke in every sip.

McDonald's has a unique relationship with the Coca-Cola brand, as Coke has helped McDonald’s expand over time and will not sell its syrup at a lower price to other businesses.
