10 Best Sumatra Coffee: Unusual Beans with Extraordinary Flavor

| ,

What makes Sumatra coffee so special and why do many people either love it or not? We’ve spent hours putting together our list of the best Sumatra coffee beans for your enjoyment.

Ever wonder what makes Starbucks coffee unusually delicious? It’s all in the choice of coffee beans! As a matter of fact, Starbucks uses Sumatra coffee beans in some of its coffee blends to balance the taste of its roast. That’s why Starbucks is one of the primary buyers of the Sumatran roast. 

What is Sumatra Coffee?

Sumatra coffee exhibits an earthy, mossy, and spicy flavor. Some love the earthy and depth of flavor of this coffee blend. Others despise it and prefer coffee blends from Ethiopia or Costa Rica. If you’re searching for a premium gourmet coffee from the Sunda islands, the Mandheling, Lintong, and Ankola are some of the recommended coffee.

Where does Sumatra Coffee come from?

Sumatra is generally harvested from the Sunda islands. Sunda is a group of islands in the Malay archipelago that is also located in the green coffee belt. It is divided into two principal regions: the Greater Sunda and the Lesser Sunda. 

The Greater Sunda is composed of big islands where Sumatra is included along with Java, Sulawesi, and Borneo. The Lesser islands are islands that you may find at Maritime Southeast Asia, north of Australia.

Although Indonesia has 17,508 islands, with 6000 of it being inhabited, Sumatra is one of Indonesia’s significant islands with coffee as its prime crop. It’s an island in Southeast Asia that is ideally suited for Arabica coffee cultivation. 

The Sumatran soil is well-balanced due to ando soils, a fertile soil developed from the andesitic volcanic sediments. These sediments came from the different volcanoes that you can find on this island. Two of the most active volcanoes in Sumatra are the Marapi and Karinci.

Aside from these, the island experiences a tropical climate which is ideal for growing Arabica coffee plants. There are seasons of rains and sunshine throughout the year. That’s why Sumatra is considered as one of the coffee paradises in Southeast Asia.

Why is Sumatra coffee lower in acidity?

For coffee lovers with sensitive stomachs, low acidity Sumatra is the most recommended coffee blend. This coffee has a low level of acidity because it is cultivated in low elevations. Some roasters reduce the acidity in coffee by mixing stomach-soothing powder with a non-invasive taste. Other coffee blends that are low in acidity are Brazil, Guatemala, Peru, and Mexico.

Since Sumatra is less acidic, it is usually roasted between medium to dark roast. Compared to Mexican and African coffees, Sumatran coffee has more body and mouthfeel finish. 

Does Sumatra Coffee have more caffeine?

Sumatra coffee contains caffeine because it is harvested from Arabica coffee plants of the Bourbon and Typica varietals. Most Arabica coffee beans have 1.5% caffeine content. Yet, its caffeine level is less than what Robusta coffee beans contain, which is 2.7%.  

However, the coffee beans’ origin is not enough proof to describe the level of caffeine in a bean. Factors including the processing method and roasting can help you understand how much caffeine there are in the coffee beans. Generally speaking, Sumatra coffee has the same caffeine quantity as other Arabica coffees.

Facts about Sumatra Coffee

Coffee was first introduced to Southeast Asian soil back in the 17th century when the Dutch brought coffee to one of the Greater Sunda Islands, Java. Initially, the Dutch first brought the Arabica beans in the Indian soil to cultivate but failed miserably. 

However, the Javanese were forced to switch to Robusta by the 19th century. A strain of rust disease destroyed thousands of Arabica coffee plants. For love for Arabica coffee beans, small coffee farmers still planted this variety of coffee using the Dutch equipment and methods. Most of the Arabica coffee bean imports come from small coffee farms in Sumatra and Sulawesi.

To understand the origin of the Sumatra Coffee, here are some interesting Sumatran Coffee facts.  

  • Sumatra coffee is processed using the wet hull method or Giling Basah.
  • The Giling Basah method involves the following processes: coffee cherries’ outer skin removal, drying the mucilage for a day, rinsing, and drying coffee cherries for the second time. Lastly, the cherries are hulled and processed.
  • The Sumatra coffee has two varieties: the regular bean and the aged bean.
  • The aged Sumatra coffee bean has spicy notes, which is unique to this bean. When blended with other coffee beans, it amplifies the flavors of different coffee beans.
  • The famous Sumatra Mandheling coffee is named after the Mandailing natives that cultivate the top specialty coffee. This Sumatran coffee grows in the volcanic soil in an elevation between 2500 and 5000 feet above sea level. It is produced in the coffee farms near Padang, the capital city of the West Sumatra province.
  • Sumatra coffee is independently cultivated by small coffee growers, with farms sizing to roughly 2.5 acres. These farms work together as a structured cooperative to sell their coffee products and divide the profits equally. (Please read our Pachamama Coffee Review to learn more about coffee cooperatives!)
