“100% arabica” and “arabica and robusta blend” describe a coffee's composition. This is useful information, but it cannot tell you on its own which coffee you will enjoy most. When choosing coffee beans, consider origin, roast, preparation guidance and tasting notes alongside it.
What does composition mean?
Arabica and robusta refer to types of coffee with different characteristics. As Nespresso explains in its arabica and robusta comparison, they can offer different profiles, including fruity, cereal, nutty or woody notes. These are tendencies, not a guaranteed description of every pack.
For a blend, a label such as 70% arabica and 30% robusta describes its composition. It does not mean 70% intensity or allow you to calculate the caffeine in a cup. If the proportions are not stated, do not infer them from the name or bean colour.
Read four details together
- Composition: species and proportions, where declared.
- Origin: growing country or region; do not confuse this with the roaster's country.
- Roast: the manufacturer's description and recommended preparation method.
- Tasting notes: sensory references that help compare the expected profile.
A “chocolate” note describes a perceived flavour or aroma; it does not prove that chocolate has been added. Check the product information to find out whether it contains added ingredients.
Turn the label into a practical comparison
Choose two options with identifiable differences and prepare them using the same equipment. Record the dose, drink quantity and any adjustments needed. Taste first without sugar, then as you normally drink your coffee. If you enjoy it with milk, include that preparation in your comparison.
Avoid choosing solely by the word “intense”: scales from different brands may not be comparable. There is also no universal percentage that suits everyone and every machine.

From composition to choosing coffee
After comparing arabica and robusta, read our coffee roasting guide to separate composition from bean treatment. For an automatic machine, the bean selection guide helps turn label information into a tasting with your usual recipe.
