Arabica
Arabica coffee beans are responsible for 75% of the global production. Arabica beans are more mild and sweeter than Robusta, and come in different flavors. The aroma and taste of coffee are affected by the conditions under which it is grown and the processing methods employed.
The word "coffee" is derived from the Arabic word that means berry. Coffee beans are actually seeds that grow inside bright red berries. It is believed ancient Ethiopian shepherds noticed that their goats were energized by eating these berries. The cultivation of coffee quickly spread around the world.

Blending is a way to control the flavour, aroma as well as body and acidity of the coffee. It is usually preferred to achieve an even and consistent taste that appeals to a larger market.
Robusta
Robusta beans (Coffea canephora) are the second most popular type of coffee bean grown in the world. They have more caffeine per bean and are more protected against diseases and pests. They also have higher levels of chlorogenic acids that are antioxidants naturally found in. However, these acids may cause oxidation during the coffee brewing process and can cause undesirable flavors.

While it may seem counterintuitive Robusta beans are frequently combined with arabica to create coffee blends. If you notice the names of countries such as Uganda or Kenya listed on a bag of coffee and you can be sure that there's some Robusta in there as well.
Most roasters employ a mixture of arabica and coffee beans to cut costs and ensure quality. To preserve the flavor integrity, you should choose the best quality beans from a reliable source. The best method to achieve this is to buy your beans directly from the farmer.
