Why Coke tastes better at McDonald’s than anywhere else?

If you think Coke tastes better at McDonald’s than anywhere else, you are not alone.

If you’ve never had a Coca-Cola from McDonald’s, you’re truly missing out. But if you have had the pleasure of slurping down a Coke under the Golden Arches, then you already know the secret: Coke from McDonald’s tastes better than cola from any other fast food joint, or even soda from the bottle.

That delicious secret isn’t happenstance. It’s for very specific reasons.

Some people claim it’s because there’s more syrup in the Coca-Cola at McDonald’s. Others say it’s the contrast between the saltiness of McDonalds’ fast food with the sweetness of Coca-Cola, making you crave the sugary drink more. But is there more to this?

A new theory has emerged, and it’s largely due to the unique relationship between McDonald’s and Coca-Cola. After all, McDonald’s is Coca-Cola’s largest customer. Starting from the 1950s, they each helped one another grow into two of the largest companies in the world.

Their partnership was so close that Coca-Cola began customizing it’s delivery system for McDonald’s. While other restaurants received Coca-Cola in plastic bags, Coca-Cola used stainless steel tanks for McDonald’s. People now suspect it’s these stainless steel tanks that preserves the freshness of Coca-Cola as its being transported all around the world.
