The coffee beans produced in Java, Sumatra and Sulawesi, especially Java, are beans called W, I, B, which are a little round. They are the highest grade of Robusta varieties and are very suitable for making mixed coffee, so they are widely used.

Robusta varieties are not easy to grow mold, so if mixed with Arabica species, it can produce a good variety with good taste and strong disease resistance. Java Robusta coffee, once roasted, is bitter, not strong in flavor, but not sour. It is often used to make mixed or instant coffee.

Romsda (Java): as the ideal bean for mixed coffee, it has little acidity, strong bitterness and few pure drinks. It is the representative variety of Nanyang coffee. If the comprehensive coffee is mixed with Romsda coffee, the concentration and sweetness of the coffee can be increased.
