Arabica constitutes the largest, approximately 70% share in worldwide coffee production, and its cultivation is much more expensive. The benefit of such an investment is a more delicate and nuanced flavor, which will definitely be appreciated by every coffee enthusiast. Robusta is much less refined, but stronger – it contains significantly greater amounts of caffeine, essential to all coffee lovers, not only in the morning. The Robusta bean brew contains from 1,8 to 4% of caffeine, while Arabica contains only up to 1,5%, depending on where it is cultivated. Which one should you choose then? How about both? A classic espresso blend consists of 40% Brazilian Arabica, 40% Robusta and 20% of high quality Arabica beans which supplement the coffee with more subtle flavors and aromas. It is also worth remembering, that the type is only a partial answer to the question about good coffee. There are also factors such as conditions of cultivation, method of processing and roasting, and others which affect the coffee’s flavor.
