FrontStreet Coffee: Introduction to the Three Major Coffee Varieties

Arabica

Raw Arabica beans are smaller than Robusta beans, somewhat oval in shape, with a smoother and more complete back. Main producing regions include Ethiopia, Nicaragua, Costa Rica, Brazil, and various countries in Central and South America. They are also known as small-fruit coffee beans.

The coffees we commonly hear about, such as Mandheling, Blue Mountain, and Brazilian coffee, all belong to the Arabica variety. Because of their higher value, Arabica beans account for nearly 70% of global production.

Arabica beans offer better flavor and higher bean grades, and are typically more expensive than Robusta beans - sometimes two to three times more costly. They have lower caffeine content (between 0.9% and 1.2%), and contain more fat and sugar than Robusta, which makes them taste more fragrant and sweet, with aroma and wine-like acidity. Their higher quality makes them more popular among coffee enthusiasts.

Depending on the growing environment, water availability, location, and soil, each bean develops different colors and flavors. This is why we have varieties like Blue Mountain coffee, Golden Mandheling, and Ethiopian coffee beans. Based on the aroma and mouthfeel of each bean, there are suitable roasting temperatures and brewing techniques. The reason baristas become baristas is that they understand the taste and flavor of every coffee bean, brewing them according to their unique characteristics to fully express each bean's distinctive qualities.

Robusta

Robusta beans are shorter and more rounded than Arabica beans, and less smooth. Main producing regions include Africa, Vietnam, Indonesia, and parts of West Asia. Typically, Robusta is mixed with Arabica to reduce the cost of coffee powder. However, Robusta is not added just because it is cheaper - sometimes it is incorporated to enhance the coffee powder's flavor. Because Robusta has richer crema, some people prefer Robusta over Arabica.

Robusta plants have stronger vitality and better environmental adaptability, making them easy to cultivate. They are typically grown at altitudes below 800 meters. Compared with Arabica, they are less affected by pests, harsh climates, and other factors. They require minimal care - even left in the wild, they can grow. Harvesting is generally done by machine, which saves labor and time.

Most Robusta varieties do not have the rich aroma of Arabica beans. They have higher caffeine content (between 1.6% and 2.4%), and lower fat and sugar content than Arabica. Their taste is quite bitter, but this does not mean their grade or quality is necessarily inferior to Arabica. Good Robusta can enhance coffee's mouthfeel and flavor, and some high-quality Robusta beans can even be more expensive than Arabica beans. Most Robusta coffee beans are used for instant coffee or coffee bags, typically not as freshly ground and brewed coffee powder.

Liberica

Its fruit is larger, sometimes more than twice the size of Arabica beans. The main producing region is Liberia in Africa. Due to its low economic value and inferior taste compared with the previous two varieties, it is mainly consumed by people in Northern Europe, and fewer people are cultivating it.

Knowledge Point

"Arabica" is not synonymous with good coffee. Even within the Arabica species, there are grade differences.

FrontStreet Coffee Recommendation

Among coffees, Mandheling is one of the most beloved full-bodied profiles, and FrontStreet Coffee's PWN Indonesia Golden Mandheling is the standard-bearer. Coffee came to Indonesia's Java in the late 17th century by way of the Dutch, and after coffee leaf rust devastated Java in the early 20th century, the industry moved north to Sumatra, which now produces more than 60% of the country's coffee. Sumatra's northern Aceh and North Sumatra provinces grow Arabica at higher elevations, mainly around Lake Tawar in the Gayo highlands and Lake Toba in the Lindong region. The region's rainy overlap with the harvest gave rise to the distinctive wet-hulled process, developed since the 1970s: the skin and pulp are removed and the beans partially dried, then the parchment is stripped off while the beans are still half-wet and semi-dry, exposing them to the air to speed drying.

Golden Mandheling is the best representative of that style. The PWN company applies extremely strict standards, using beans of 18 screen and above and requiring fewer than 3 defective beans per 300g green sample to meet the top G1 grade, then adding three rounds of hand sorting to remove defects and boost the cup's cleanliness and sweetness. The result is even, plump, translucent beans with a low defect rate, and after a medium-dark roast it carries a rich roasted aroma, a clean cup, and a full body - ideal for anyone who dislikes acidity.

FrontStreet Coffee's Lindong Mandheling shows the traditional side of the style: aromatic and full, bitter-sweet, with a strong, stimulating entry, clove and woody aromas, low acidity, spice and mint notes, and a long, thick, sweet finish. If you want to use Mandheling on an espresso machine, FrontStreet Coffee's Classic Blend adds medium-dark Mandheling to the creamy nut character of Brazilian coffee, so butter, roasted chestnut, and caramel come to the fore, while the Mandheling lifts the body and lends sandalwood, herbal, and spice notes; a small amount of Robusta rounds out the crema, making latte art and layered Dirty drinks easy to pull.
