Many coffee shops advertise themselves with "100% Arabica." When a coffee bean or powder can carries that line, the price is rarely low. Could Arabica really be the premium label of the coffee world?

Understanding Arabica

Arabica is one of the world's most important coffee tree species, accounting for roughly 65%-80% of all coffee beans produced. The claim "100% Arabica" describes the species and nothing more; it carries absolutely no implication of quality or excellence.

Coffee trees are shrubs or small trees of the Rubiaceae family. Ripe coffee fruit looks like a cherry: bright red, with sweet flesh, and a pair of seeds inside that are the coffee beans. Whenever people mention coffee, they usually mean the fruit of one particular species, and that species is Arabica. Arabica is the world's main coffee bean, grown across dozens of producing countries between the Tropic of Cancer and the Tropic of Capricorn.

Getting to Know Arabica Coffee Beans

1. Arabica is a premium coffee species widely used commercially

Arabica is naturally low in caffeine, with content about one-half to one-third that of Robusta. Grown at different altitudes, Arabica produces beans with significant taste differences, offering diverse flavors with distinctive character. Blending coffee from different origins is another natural advantage of the species, making coffee taste richer.

2. Arabica's high price comes from difficult cultivation

Arabica's growing conditions are demanding: higher altitudes, from above 600 to 2000 meters, fertile soil, sufficient humidity, appropriate sunlight and shade. That is not all. Arabica trees have poor resistance to pests and disease and are easily damaged, so the annual yield per unit area is also lower.

3. Blue Mountain Coffee is one of the earliest sub-varieties of Arabica

Among the Arabica family, three earlier sub-varieties are the Blue Mountain varietal, the Typica varietal and the Bourbon varietal. Blue Mountain Coffee, taking advantage of Jamaica's unique natural conditions, has become recognized as the world's finest coffee. Note, though, that 99.9% of the Blue Mountain Coffee available in China is simply grown near the Blue Mountain range. Only coffee produced from the 6,000 hectares of land above 1600 meters altitude can truly be called Blue Mountain, and production has always stayed below 900 tons. Most importantly, 90% of the world's Blue Mountain Coffee is bought by Japanese buyers.

Arabica is not the only coffee tree species, however. More than 120 coffee tree species have been identified to date, but only one rivals Arabica in popularity: Coffea canephora, commonly known as medium-grain coffee, or Robusta.

Understanding Robusta

1. Robusta is difficult to grow

The term Robusta is essentially a brand name that promotes its coffee tree species' characteristics. It was first discovered in the late 19th century in what was then the Belgian Congo (the Democratic Republic of Congo). Compared with Arabica, Robusta can be planted and bear fruit at lower altitudes, adapts to high temperatures and resists disease better. Because its growing requirements are less strict, the cost of producing Robusta beans is much lower. Robusta also has an unavoidable drawback: the coffee is not very tasty.

2. Robusta is mainly used for instant coffee production

Robusta does of course come in different grades, and high-quality Robusta can be produced. For many years Robusta has been an important component of espresso culture, but in recent years most of the Robusta grown worldwide has ended up in large commercial factories, turned into the most despised product in the industry: instant coffee.

3. Robusta is actually one of Arabica's parents

The coffee industry has always treated Robusta as Arabica's ugly sister, until an interesting genetic discovery revealed the truth. Once scientists compared gene sequences, they found that the two species are not siblings or cousins at all: Robusta is actually one of Arabica's parents. The most likely birthplace of Arabica is southern Sudan, where Robusta cross-pollinated with another coffee species, Eugenioides, creating an entirely new plant, Arabica. This new species subsequently branched out and spread to Ethiopia to continue reproducing, and Ethiopia has long been considered the origin of coffee ever since.

How to Distinguish Between Arabica and Robusta

From appearance:

Arabica coffee beans are smaller and oval on the front, with a narrow, curved crack down the middle. The back of the bean has a relatively flat arc, somewhat like half a peanut.

Robusta coffee beans are larger and rounder on the front, with the cracked side slightly puffed up and very straight grooves. The back is round and convex.

From flavor perspective:

Arabica beans possess varied and broad flavor potential. Grown in different regions, altitudes and climates, Arabica develops its own character, showing completely different personality flavors. Unroasted, it smells of fresh grass. After an appropriate roast it displays fruit aroma at light to medium roast and caramel flavor at dark roast. It suits both single-origin and blended use, and can be brewed by a range of methods, from French press and drip to espresso machine.

Robusta beans usually taste plain, dull and pungent. Because most Robusta worldwide is grown at low altitude, with the exception of the rare high-altitude, high-quality washed Robusta now grown in India, flavor differences between regions and climates are not significant, and the coffee lacks personality. Unroasted, it smells of raw peanuts. Cheap Robusta after roasting usually shows flavors somewhere between wheat tea at light to medium roast and rubber tire at dark roast, and it struggles to display delicate flavors.
