What is the real deal with caffeine in coffee?
Coffee is one of the most popular drinks in the world and is valued above all for its invigorating effects, which it owes to the caffeine it contains. The exact amount of caffeine in coffee depends on a number of factors, including the type of coffee, how it’s made and the cup it’s served in – here’s a quick rundown of the key points:
The type of coffee: There are different types of coffee beans that contain different amounts of caffeine. Arabica beans are the most common and typically contain less caffeine than Robusta beans. So the type of coffee you drink affects the amount of caffeine you consume.
The manufacturing method: The manufacturing method of the coffee also affects the amount of caffeine in the drink. The brewing process plays a role here. Filter coffee usually contains less caffeine than espresso in 100 ml, but due to the larger quantities that are drunk, you usually consume more caffeine than with the same number of espressos.
The cup: The size of the cup that the coffee is served in also affects the amount of caffeine in the drink. A small cup (e.g. a cup of espresso) therefore contains less caffeine than a large cup (e.g. a cup of filter coffee).
In summary, the amount of caffeine in coffee depends on various factors. Basically, however, it can be said that a cup of black coffee contains around 95 mg of caffeine, which is about as much as a cup of tea.
What does caffeine do to us?
Most people drink coffee because they are tired and want more energy. Caffeine causes heart rate to increase and blood vessels to dilate. As a result, the blood is transported through the body faster and the muscles are better supplied with oxygen. Caffeine is therefore a pleasantly effective stimulant that increases physical and mental performance. If you are hypersensitive to caffeine, we recommend the equally aromatic variety “Without” from our NABER Viennese coffee factory, available as beans, capsules or ESE pods. The invigorating effects of caffeine generally don’t last long. After about one to one and a half hours, the body begins to break down the caffeine. Then the heart rate drops again and the blood vessels contract again to their normal size.
