FrontStreet Coffee briefly describes the relationship between roast level and caffeine content.

The Relationship Between Roast Level and Caffeine

Actually, the roast level does not affect caffeine content. What truly plays a decisive role is the coffee bean variety. Common coffee bean varieties include Arabica and Robusta, with the latter having the highest caffeine content. According to tests, the caffeine content in Arabica coffee is only half that of Robusta coffee.

About Coffee and Health

Drinking too much coffee may cause a series of adverse effects on the body, such as irritability, insomnia, and trembling limbs. MedlinePlus suggests that normal adults should drink no more than 3 cups of coffee per day, as this intake level will not bring any negative effects to the human body.

Additionally, you must also pay attention to caffeine intake from other sources. It's important to know that caffeine is widely present in plants, so products such as soda, tea, and chocolate also contain caffeine. Medications like aspirin also have high caffeine content, so you must comprehensively consider all sources and strictly control your daily caffeine intake.
