McDonald’s points to pre-chilled water and syrup, a syrup ratio that accounts for melting ice, filtered water and a slightly wider straw. The way it serves the drink gets a lot of attention.

McDonald’s chills the water and Coke syrup first

According to McDonald’s own explanation, both are chilled before they reach the dispenser. The fountain system stays cold, too.

The syrup ratio accounts for melting ice

The company says its serving ratio allows for ice to melt. That’s more precise than saying it has a secret extra-sugary recipe.

It also doesn’t establish that ordering without ice is a guaranteed sweeter-drink trick. McDonald’s doesn’t make that promise in its explanation.

The water gets filtered

McDonald’s says it filters the water before it enters the fountains. Its FAQ doesn’t claim that every other restaurant uses an inferior system.

Yes, McDonald’s mentions the straw

The chain says its straw is a little wider than a typical one to let more Coke flavor reach your taste buds. That’s its explanation, rather than proof that everyone will prefer the drink.

Does everyone think McDonald’s Coke tastes better?

Taste is personal. You can prefer a can, a bottle or another restaurant’s fountain Coke. McDonald’s describes steps it takes to serve its soda consistently, not a taste-test result that settles the argument.

So if you’ve always thought the drive-thru Coke hits differently, those are the details the company actually confirms.

For the other half of that order, here’s what to know about requesting fresh McDonald’s fries and why the vegan answer changes by country.
