Three Major Coffee Varieties

Arabica, Robusta, and Liberica are the three main coffee varieties, though Arabica and Robusta are the most commonly traded on the market. Each variety has its own strengths and weaknesses, with different purposes and uses.

Arabica: Premium Coffee Beans with Excellent Flavor and Aroma

Arabica is a representative variety originating from Ethiopia and is also produced in South Africa, African, and Asian countries, accounting for 70%-75% of world coffee production. Arabica has weaker resistance to pests and diseases, making highland areas more suitable for cultivation. Arabica beans grown above 1500 meters are of the best quality.

Ancient Pure Varieties of Arabica: Typica and Bourbon

Typica

Typica is the original variety of all Arabica types. Typica originates from southern Sudan, and its mature fruit is red. It has relatively low yield and extremely poor disease resistance, but its excellent cupping quality still makes it popular worldwide.

Typica Coffee Varieties: Geisha, Jamaican Blue Mountain, Hawaiian Kona, Maragogipe, Sumatra Typica (Mandheling)

Blue Mountain

Produced from the Typica variety in the Blue Mountain range of eastern Jamaica, the mountains are surrounded by the Caribbean Sea. On clear days direct sunlight strikes the azure sea surface, and the peaks reflect the brilliant blue light of the seawater—hence the name Blue Mountain. The highest peak of Blue Mountain reaches 2256 meters, making it the highest in the Caribbean region and a famous tourist destination. Located in a seismic zone with fertile volcanic soil, fresh unpolluted air, and a humid climate of year-round fog and rain (average precipitation of 1980mm, temperature around 27°C), such conditions have created the world-renowned Jamaican Blue Mountain Coffee, which is also the second most expensive coffee in the world.

FrontStreet Coffee Recommendation

Among the Typica-derived varieties, Sumatra Typica—better known as Mandheling—is one of FrontStreet Coffee's most distinctive offerings. Coffee was planted on Java by the Dutch in the late 17th century and later spread to Sumatra. After leaf rust devastated Java in the early 20th century, production shifted north to Sumatra, which today accounts for more than 60% of Indonesia's Arabica and Robusta output; only Aceh and North Sumatra grow Arabica at high altitude. Sumatra's heavy rain, humidity of 70-90%, rainfall above 2000mm, and frequent typhoons made natural or washed processing impractical, so farmers developed the region's signature wet-hulled method, removing the parchment while the bean is still semi-dry—a technique that has shaped Mandheling's flavor since the 1970s.

For the highest grade, FrontStreet Coffee recommends the PWN Golden Mandheling, produced by Indonesia's PWN company to a strict standard: beans of 18 screen or larger, fewer than 3 defects in a 300g raw-bean sample to meet the top G1 grade, then three rounds of hand-picking to remove defects entirely, which lifts the cup's cleanliness and intensity of sweetness. It is given a medium-dark roast, carrying rich roasting aromas, a clean cup, and a full body—ideal for anyone who dislikes acidic coffee.

FrontStreet Coffee's Lintong Mandheling, from the traditional Lintong area around Lake Toba in North Sumatra, is likewise wet-hulled and medium-dark roasted, showing a strong and stimulating entry with clove and woody aromas, low acidity, spice and mint notes, and a powerful, lasting sweetness. Those who want Mandheling on an espresso machine can try the FrontStreet Coffee Classic Blend, which layers a medium-dark Mandheling over Brazilian creamy nuttiness for butter, roasted chestnut, and caramel notes, with the Mandheling adding sandalwood, herbal, and spice character and a small amount of Robusta boosting crema for latte art or a layered Dirty. To brew Golden Mandheling as pour-over, FrontStreet Coffee suggests 87-88°C water, 15g of coffee, a 1:15 ratio, a coarse-sugar grind, and a three-stage pour.
