- January 16, 2025
Coffee, the favourite drink of many, is known for its delicious flavour and energising effect. But what about the amount of caffeine in your cup of coffee? Is an espresso really stronger than filter coffee, or does the brewing method make more difference? In this article, we dive into the world of caffeine. We explain how many mg of caffeine are in different types of coffee and what to watch out for. That way, you can enjoy your daily cup consciously!
What exactly is caffeine?
Caffeine is a natural substance found in coffee beans, tea leaves and even cocoa beans. It acts as a stimulant on your central nervous system, making you feel more alert and energetic. Once you drink a cup of coffee, the caffeine is quickly absorbed into your blood and reaches your brain within 15 to 30 minutes.
What does caffeine do exactly? It blocks a substance in your brain, adenosine, which normally slows down your brain activity and makes you sleepy. The result? You feel more awake, sharper and maybe even a little euphoric.
How many mg of caffeine are there on average in a cup of coffee?
The caffeine content in coffee can vary greatly depending on the type of coffee, the brewing method and the size of your cup. Below you’ll find an overview of some common coffee types:
| Type of coffee | Caffeine content in mg (average) |
|---|---|
| Espresso (30 ml) | 60-80 mg |
| Filter coffee (120 ml) | 90-120 mg |
| Instant coffee (120 ml) | 60-85 mg |
| Decaf (120 ml) | 2-5 mg |
| Ristretto (20 ml) | 50-65 mg |
| Americano (120 ml) | 60-100 mg |
| Cold Brew (240 ml) | 150-240 mg |
| Cappuccino (150 ml) | 60-80 mg |
| Latte (240 ml) | 60-80 mg |
The amount of mg caffeine in coffee depends on several factors, such as:
- The bean type: Robusta beans contain about twice as much caffeine as Arabica beans.
- The roasting process: Lightly roasted coffee often has a higher caffeine content than dark roasted coffee.
- The brewing method: The longer the water is in contact with the coffee, the more caffeine is extracted.
With this knowledge, you can consciously choose how much caffeine you consume. Whether you need a strong espresso or a mild decaf, the choice is yours!
Caffeine content in other drinks and foods
Besides coffee, there are many other drinks and foods that contain caffeine. It’s interesting to see how they compare. Here are a few well-known examples:
| Product | Caffeine content in mg (average) |
|---|---|
| Black tea (200 ml) | 30-50 mg |
| Green tea (200 ml) | 20-35 mg |
| Energy drink (250 ml) | 80-100 mg |
| Dark chocolate (50 g) | 20-30 mg |
| Cola (330 ml) | 30-35 mg |
| Decaf tea (200 ml) | 0-5 mg |
How much caffeine is too much?
Although caffeine can be a nice pick-me-up, it’s important to consume it in moderation. The European Food Safety Authority (EFSA) recommends a maximum daily intake of 400 mg caffeine for adults. This corresponds to approximately:
- 5 cups of filter coffee
- 10 cups of black tea
- 5 energy drinks
For pregnant women and breastfeeding mothers, a lower limit applies: a maximum of 200 mg caffeine per day.
What happens with too much caffeine?
Excessive caffeine intake can lead to:
- Heart palpitations
- Restlessness
- Sleep problems
- Headaches
- Nausea
An acute "overdose" of caffeine, where more than 600 mg is consumed in a short time, can even cause severe symptoms such as tremors or panic attacks. Fortunately, this rarely occurs with a normal diet.
Tip: Keep track of how much caffeine you consume daily, especially if you drink tea, cola or energy drinks alongside coffee. This way, you can enjoy your daily caffeine moments in a healthy way!
Whether you love a strong espresso or prefer a gentle latte, a bit of knowledge about caffeine helps you enjoy your favourite drink even more. So take that next sip, knowing exactly what’s inside. Cheers!
