Are you drinking straight from aluminum cans or plastic bottles, or is it McDonald’s fountain pop through a paper straw?
These details matter. A cold can of Diet Coke can’t be beat. But the Coke Zero is the better option at McDonald’s…
I have a system. I prefer not to drink from the can.
For this test, I'll pour each into an identical red plastic cup, like the college kids use for beer pong. I'll chill some cups now.
