Decaf coffee is increasingly sought after by people who still want a daily cup of coffee but don't want heart palpitations, insomnia, or stomach upset. This guide explains what decaf coffee is, how much caffeine it actually contains, who it's suitable for, and how to choose a good decaf coffee.
What is decaf coffee?
Decaf coffee (from decaffeinated) is coffee that has had most of its caffeine removed before the beans are roasted. The process takes place while the beans are still green: the beans are moistened, then the caffeine is "pulled" out with water, carbon dioxide, or a special food-safe solvent. The beans are then dried and roasted like regular coffee.
The result is still coffee: the aroma, bitterness, and body are still there. The only thing drastically reduced is the caffeine. In many countries, the term decaf is used for coffee that has had about 97% or more of the caffeine removed.
Decaf coffee = low caffeine coffee, not zero caffeine
This is a common misconception. Decaf coffee still contains a small amount of caffeine, so it's more accurately called low caffeine coffee. As a rough illustration:
- A cup of regular brewed coffee (±240 ml): around 80–100 mg caffeine.
- A cup of decaf coffee of the same size: generally only about 2–15 mg.
The exact amount depends on the type of bean, the decaf process, and the brewing method. But the difference is clear: a cup of decaf contains only a fraction of the caffeine in regular coffee. Therefore, many people can drink decaf coffee in the afternoon or evening without disturbing their sleep.
Who is suitable for drinking decaf coffee?
- Caffeine sensitive people — easily nervous, hands shaking, or restless after drinking regular coffee.
- Who wants to sleep better — caffeine can linger in the body for hours, so an afternoon coffee can disrupt your nighttime sleep.
- Those who want to reduce caffeine without giving up coffee — the coffee ritual remains, just reduce the caffeine.
- Elderly people and those who are regulating their caffeine intake on the advice of a doctor — for example, due to high blood pressure, pregnancy, or certain medications. For conditions like these, first ask your doctor about safe limits.
Is decaf coffee healthier?
