Anybody who's ever ordered a Coca-Cola at McDonald's knows that it's better than what you'd find at any other soda fountain. We'd even go so far as to say it's better than Coke straight from the can or bottle (and that's even including Mexican Coke). You've probably heard other people wax poetic about the merits of McDonald's Coke. But it's not just you, and it's not just in your head: there are scientific reasons why Coke tastes better at McDonald's. It’s the reason why your first sip of McDonald’s Coke tastes so special—but it’s also why your soda never ends up watery.
