Which brings us to our first question: What IS Arabica? Arabica is a species of coffee indigenous to the mountains of Ethiopia prior to its spreading to coffee growing regions around the world. It is believed to be the first species of coffee to be cultivated.
Arabica is said to produce better tasting coffee than other coffee species, and there is a reason why: Caffeine. Or the lack of it. Highly caffeinated coffees, like Robusta which has twice the caffeine as Arabica are consistently and exceedingly bitter to the taste. Arabica contains less caffeine than any other commercially cultivated species of coffee and therefore has the most natural sweetness. In the cup, a well-prepared espresso borne of exclusively high-quality Arabica is noticeably aromatic with a natural sweetness and pleasing acidity with only a mild bitterness.
