What do you get when you take two or more types of coffee beans and put them together? A coffee blend! By combining different types of beans as well as adding flavors, a coffee professional can give coffee a more complex or balanced taste. Coffee beans, whether Arabica or Robusta, can have very different tastes if they are from different regions. Some beans may have a good level of acidity but lack aroma, body or color. A blend may be made of up of two or ten different types of beans in varying quantities in order to get a good balanced blend. Roasting is also part of blending, as beans can be heavily roasted to have a strong flavor or lightly roasted for a milder taste.
