The Unique Taste of Sumatra Coffee
Nestled in the heart of Southeast Asia, Sumatra is home to a diverse ecosystem that nurtures the growth of some of the world’s most sought-after coffee beans. The island’s rich volcanic soil and unique processing methods give Sumatra coffee its unparalleled taste, featuring earthy undertones, spicy nuances, and a sweet complexity that sets it apart from other coffees.
The distinctive taste of Sumatra coffee emanates from the Giling Basah processing method, also known as wet hulling. This technique gives the beans a different flavor and reduces acidity, resulting in a rich, full-bodied taste that entices the palate. Coffee enthusiasts highly prize Sumatra coffee, attributing its appeal to optimal growing conditions yielding flavorful beans and the Giling Basah processing method that neutralizes acidity.
Earthy Undertones
Sumatra’s rich volcanic soil and unique processing methods contribute to the earthy flavors found in its coffee beans. The characteristics of Sumatran coffee include:
Rich and earthy flavors
Distinct flavor profile
Nutty undertones
Low acidity
The volcanic soil provides the necessary nutrients and minerals for the coffee plants to thrive, resulting in the distinct flavor profile of Sumatran coffee. The wet-hulling processing method, Giling Basah, further enhances these earthy flavors, setting Sumatra coffee apart from other beans.
While Sumatra coffee is known for its earthy undertones, it’s not alone – Costa Rican Poas Tierra Volcanica coffee and Poas Volcanic Earth blend also have a similar flavor profile, thanks to the mineral-rich volcanic soil they’re grown in.
Spicy Nuances
The wet hulling process and inherent bean characteristics give rise to the following flavors in Sumatra coffee:
Rich flavors of earthiness
Complexity
Cedar
Spice
Herbal notes
The wet hulling process imparts distinctive earthy, herbal, and sometimes spicy notes to the flavor profile.
Some specific Sumatra coffee varieties exhibit the following flavors:
Spicy
Earthy
Wild
Mushroomy
Fruity
Floral
With their rich flavor, these particular flavors make them a delightful experience for the adventurous coffee drinker.
Sweetness and Complexity
A combination of growing conditions, processing, and roasting techniques contribute to the sweetness and complexity of Sumatra coffee. The humid tropical climate, rich volcanic soil, and high altitudes contribute to the coffee’s sweetness and complexity. The wet hulling process, or Giling Basah, further enhances the sweetness and richness of the coffee by creating a unique drying method, signature characteristics of the beans, and a unique technique.
The end result is a rich, full-bodied cup with a smooth, sweet, and intense flavor that leaves a lingering sensation on the back corners of the tongue, with chocolatey notes in the finish.
The Role of Wet Hulling in Sumatra Coffee’s Quality
Wet hulling significantly impacts the quality of Sumatra coffee, adding to its full-bodied, smooth mouthfeel and preserving its distinctive flavors. During the wet hulling process, the de-pulped beans are left to ferment overnight before the remaining pulp is removed by hand and the beans are left to dry on a patio.
This unique processing method enhances the flavors and characteristics of the beans, making Sumatra coffee highly sought after by coffee drinkers worldwide.
Reducing Acidity
The wet hulling process in Sumatra coffee involves the following steps:
Rapidly drying the coffee beans until they reach approximately 50% moisture.
At this point, the beans are still swollen inside.
Removing the hull and husk.
Preparing the beans for export.
This process lowers acidity in Sumatra coffee, making it more palatable for those sensitive to acidic coffees.
This method is commonly used in Indonesia and contributes to Sumatra coffee’s smooth, earthy taste.
Enhancing Body and Mouthfeel
Wet hulling contributes to Sumatra coffee’s full-bodied, smooth mouthfeel, setting it apart from other coffee types. The wet hulling process in Sumatra coffee influences the mouthfeel by creating a rich robust, syrupy body with low acidity, resulting in a distinctive flavor profile that sets it apart from other coffee beans.
The wet hulling process and the unique growing conditions in Sumatra create a unique taste and aroma in its coffee, making it a favorite among coffee connoisseurs worldwide.
Preserving Distinctive Flavors
The wet hulling process helps preserve the unique flavors of Sumatra coffee, ensuring a rich and satisfying cup. During the wet hulling process, the beans are depulped and allowed to undergo fermentation in water-filled tanks. The beans are then hulled and dried, creating a rich and rustic flavor that is unique to Sumatra coffee.
This process, involving coffee cherries, results in a complex and piquant earthy chocolaty factor that is characteristic of Indonesian island coffee.

Arabica beans from Sumatra offer a more refined flavor profile compared to Robusta beans, which can be harsh and bitter. Sumatra Arabica coffee beans have a rich, full-bodied taste with a smooth, sweet, and intense flavor, while Robusta coffee beans tend to be nuttier, more bitter, and have a stronger, earthy flavor with higher acidity.
The superior taste of Sumatra Arabica coffee bean makes it highly sought after by coffee drinkers around the world.
