It is better to mix coffee with several different beans.

Since it is a blending, it naturally refers to the blending of more than two kinds of raw beans, but a special example is that it can also match the same kind of coffee beans with different roasting degrees, or even the new crop and aged coffee or old crop of the same kind of coffee beans, so the type referred to in the blending is no longer a coffee variety in a narrow sense, but extends to the flavor of coffee in a broad sense. Generally use 2 to 6 kinds of coffee beans when blending, too many kinds will not be able to show the unique flavor of coffee.

Blended coffee usually does not take the 1:1 blending ratio, because this may suppress each other's unique flavor, so the blending must be primary and secondary in order to produce a better taste than a single coffee. If you want the coffee to taste complex and changeable, you can reduce the proportion of raw beans, and vice versa.

The blending of coffee depends on constant attempts, so a blending schedule should be drawn up mathematically before blending, and then the best plan should be determined through the process of blending-tasting cups.

Do not think that this is a negative and stupid approach, in fact, it is only through the experience, inspiration and painstaking attempt of the blender that you can make a good cup of coffee and not just mix the beans together. Sometimes the blending of two kinds of boutique coffee will suppress each other's unique flavor; blending is not simply blending several kinds of boutique coffee together. Matching is like the painter adjusting and creating charming colors in the color palette, the mixer can reconcile the attractive taste according to the different characteristics of the coffee beans. It is no exaggeration to say that matching is an art. As an artist, the assembler needs not only experience and inspiration, but also scientific calculation. The emergence of works of art will not be accidental, but the outbreak of long-term accumulation.
