As much as coffee is a favorite with many people worldwide, many myths surround caffeine’s intensity depending on roast types. The types of coffee roasts are light, medium, and dark.

For this reason, those that like their coffee bitter prefer dark roasts to light roasts and assume that the longer roasting time brings out more caffeine content from the coffee beans.

Others think that light roast contains more caffeine because the shorter roasting time does not burn off the caffeine. In this article, we set to debunk any myths concerning roasting time and its effects caffeine content in your coffee drink.

Factors that affect caffeine content in coffee

Coffee gets its caffeine content from the beans, and besides the roasting time, other factors affect its levels. The factors that affect caffeine levels include the type of coffee beans, type of roast, brewing method, and coffee type.

Coffee beans

The caffeine content in your cup depends on whether you are drinking Arabica or Robusta coffee beans. Arabica and Robusta are the most popular type of coffee beans, and they come with different caffeine levels. The majority of the elite coffee houses worldwide use Arabica beans because they are better in quality compared to Robusta beans.

Even though Robusta beans have lower quality than Arabica, they contain more caffeine levels. Brewing and roasting methods are the only possible processes that alter both coffee beans’ caffeine levels.

Type of roast

The most popular types of coffee roasts are dark and light roast coffee. Dark roast has a bolder and deeper flavor than a light roast, but it does not mean that it contains more caffeine than the light roast does. Both dark and light roasts include the same levels of caffeine though some say that light roasts have more caffeine because they go through a short roasting time, which helps preserve the bean’s caffeine content. Caffeine levels depend on the number of beans that you use during the roasting process. If you have the same scoop of both dark and light roasts, you should have the same caffeine content.

Brewing method

If you use coffee brewing methods with higher extraction levels, you will have coffee with more caffeine content. Besides the brewing method, other factors that affect caffeine content during the process include water temperature and grind size.

Instant or brewed coffee

If you chose to drink instant instead of brewed coffee, then you will have less caffeine content in your coffee cup. The average caffeine content in an instant coffee cup is 65 mg, while brewed coffee contains an average of 115 mg per cup.

Conclusion

Now you know that roasting time only changes the taste and flavor of the coffee and the mass density without changing the caffeine content. Caffeine levels only vary depending on the number of coffee beans you use on your coffee cup or the other factors listed above.
