Some people like to mix Coca-Cola in their coffee — it’s a sweet and bitter combination with an extra caffeine boost.
The bitterness comes from the black coffee and the sweetness comes from the cola’s caramel flavor.
There are multiple ways to combine the two drinks. You can use both hot and cold coffee. You can also use the soda to top off or thoroughly mix it into the drink — just make sure it doesn’t bubble over! Milk can also be added to the drink.
It’s unclear how long people have been drinking the pairing, but the combo is popular enough that Coca-Cola has developed its own product called Coca-Cola Plus Coffee. It has more caffeine than a regular Coke, but less than a cup of coffee. The soda is only available in Australia, Vietnam, Cambodia, and Thailand.
This isn’t the first version of coffee soda. Coca-Cola used to have a coffee-flavored soda product called Coca-Cola Blak. Pepsi also had one called Pepsi-Kona. One of the original coffee sodas is the Manhattan Special, which was sold in 1895.
