The above factors combined with the treatment of raw coffee beans have created the diversity of coffee from different countries and regions in the world. Arabica and Canephora are two very important varieties in the commercial coffee industry. Arabica coffee accounts for 70% and 80% of all coffee production.

Although both are widely cultivated, there are significant differences in Arabica Canephora Robusta. Beans are different, plants are different, and then, their scope of use is also different. Arabica coffee has a rich and delicate taste, strong smell, high acidity and slippery texture: it is not easy to be bitter; caffeine is lower than Robusta coffee. Its excellent flavor and aroma make it the only coffee that can be drunk directly. The world-famous Blue Mountain Coffee uses Arabica coffee beans. Robusta coffee beans have a unique aroma and bitter taste, and the content of caffeine is much higher than that of Arabica.

This means that less oil is quenched into coffee, thus reducing the effect of oil on foam stability, so increasing Roberta will reduce the overall amount of oil quenched from coffee powder, which means you have a higher chance of producing a more stable and richer Crema.
