Caffeine Levels in Coffee Vs. Coke


Caffeine is a natural substance occurring in plants like tea, coffee, and cacao pods, but it can also be synthetically made to be added to products like soda. It stimulates the brain and central nervous system to keep you awake and alert and give you a pump of energy.

Many people reach for a cup of coffee or tea in the morning for the caffeine, but some prefer to get their kick from coke. Coke is one of the most consumed soda brands with the highest caffeine content. So should you reach for a cup of coffee or coke for higher caffeine content?

How Much Caffeine Is in Coffee?

According to the Food and Drug Administration, a typical eight-ounce cup of coffee contains between 80 and 100 milligrams of caffeine. However, not all coffees have the same caffeine content, and it depends on several factors.

One of the most common factors is the type of coffee beans used. Robusta coffee beans usually have a more bitter taste and a higher caffeine content than arabica beans which have a sweeter and fruitier taste.

Grind size is another factor that affects caffeine levels because finer ground coffee means more surface area of the coffee is exposed to water, meaning a higher caffeine content.

Another critical factor is the brewing method and time. The longer the coffee grounds remain in contact with water, the higher the caffeine content will be.

Whether making your coffee at home or ordering from a coffee shop, the type of coffee determines how much caffeine you get. Espresso usually has the highest caffeine content. It would help if you also considered the brand you buy from because different coffee sellers have different brewing methods and different coffee beans.

You should also consider the type of roast, whether it’s dark or light. While the roast type does not directly affect the caffeine content, it affects the mass of the beans.

Light-roasted beans are usually denser than dark-roasted beans, meaning that if you measure the same amount of the two in terms of scoops, you will get a higher caffeine content from the light-roasted beans.

However, if you use weight, you will get more caffeine from the same ounces of dark-roasted beans than light-roasted ones. This difference, however, is not usually not that much.

How Much Caffeine Is in Coke?

The amount of caffeine you get from coke depends on the type and serving you get. Classic coke contains around 21 milligrams of caffeine in 7.5 ounces, while diet coke contains approximately 28 milligrams in 7.5 ounces.

If you want to cut on caffeine levels, you can go for the decaffeinated coke drink and always check on the ingredients and content list before buying.

Final Words

Whether you’re reaching for a Coke or a Coffee when you need a caffeine boost, both are likely to give you that burst of energy that you are looking for. While the burst of energy that you feel from coffee will be stronger, Coke can also be a good source of Caffeine if you are looking for a more subtle boost. This all depends on your personal caffeine tolerance of course. We hope that this article has given you some insight into the difference in caffeine levels in Coffee vs Coke.
