Coffee is one of the world's most loved drinks, and it has a magical ingredient that speeds up our mornings and helps us through hectic work days – caffeine. Caffeine gives us the life-giving energy boost we seek, an experience that is perhaps the very best medicine to wake up our tired minds. In this article we will explore the fascinating world of caffeine in coffee, from its benefits and content to answering the most common questions on the subject.


What is caffeine?

Caffeine is a naturally occurring stimulant found in plants, including coffee beans. The chemical formula for caffeine is C8H10N4O2, and in its pure form, it appears as a toxic white powder. When consumed through brewed coffee, caffeine rapidly affects the central nervous system by blocking adenosine, a hormone that regulates sleep and wakefulness. This leads to increased attention and reduced fatigue.

What factors affect the caffeine content of coffee?

The caffeine content of coffee varies considerably depending on several factors: Coffee beans: There are several varieties of coffee beans, and each has its own natural caffeine content. Arabica beans usually contain less caffeine than Robusta beans.

  • Roasting method: Dark-roasted coffee has a deeper flavor, but usually contains less caffeine than light-roasted coffee, as roasting breaks down the caffeine.
  • Type of coffee: The caffeine content varies between different types of coffee such as brewed coffee, espresso, instant coffee and decaffeinated coffee.
  • Serving size: The amount of caffeine you get from a cup of coffee varies depending on how much you brew and serve.

How much caffeine is in a cup of coffee?

The caffeine reaction varies from person to person. Some people are more sensitive to caffeine and may experience unpleasant side effects such as rapid pulse, nervousness and anxiety. Genetic differences may play a role in how well you tolerate caffeine. Up to 500-600 mg of caffeine per day (equivalent to 6-7 cups of coffee) is considered safe for most people.

Filter coffee usually contains 50-60 mg of caffeine per deciliter, so a large cup (2 dl) contains approximately 100-120 mg of caffeine.

Espresso has a significantly higher caffeine content, with approximately 120 mg per deciliter, which is equivalent to 240 mg in two small cups of 1 deciliter.

Decaffeinated coffee is a good option for those who want to enjoy the taste of coffee without the extra dose of caffeine. Generally, 90-99 percent of the caffeine is removed from decaffeinated coffee, although the coffee is often made from older or low-quality beans that are dark-roasted to hide unpleasant flavors. However, by choosing quality beans and careful roasting, you will find that the difference in quality between decaffeinated coffee and regular coffee is minimal.

Caffeine and health

Caffeine has both positive and negative health effects, depending on the amount consumed. It is also important to distinguish between caffeine from coffee/tea and caffeine from energy drinks. Energy drinks often contain other substances such as inositol, taurine and glucuronolactone, which can affect the body's functions. These substances are also found in food, but energy drinks often contain higher levels of them, which can lead to symptoms such as nausea, palpitations, nervousness and muscle tremors, even with moderate consumption.

Coffee or energy drink?

Coffee has more health benefits compared to energy drinks. For example, a regular cup of coffee contains more caffeine than an equivalent amount of energy drink. This means you can achieve a more effective caffeine response with less sugar and fewer potential side effects. Choose coffee as your caffeine of choice for a healthier experience.
