The Story of Mandheling Coffee: The Source of Courage from Sumatra Coffee Beans and the Correct Way to Drink Mandheling

FrontStreet Coffee: The Story of Sumatran Mandheling

Indonesia is one of Asia's great coffee producers, and Mandheling is the name it is best known for. The country is made up of islands — 17,508 of them in all — which is why it has long been called the "Thousand Island Nation."

One of those islands is Sumatra, source of a coffee prized the world over for its heavy body and intense aroma. Sumatra has a story worth telling.

Sumatra was colonized in turn by the British and the Dutch, and the Japanese left their mark there too. That is where the story begins.

On February 14th, 1942, 320 Japanese aircraft came down at Palembang, in Sumatra's oil field region. The Netherlands still held the island at the time, but in less than a month the Dutch surrendered. Japan then took over the administration of Indonesia. Life for the locals was, relatively speaking, peaceful — they did not dare resist, and so they coexisted with the occupying forces.

One day a Japanese soldier was drinking coffee in a Sumatran café when he came across a cup with unusually heavy body and a powerful flavor. He asked the owner, "What is this coffee?" The owner did not understand Japanese and took the question to be about where he was from. Rolling his eyes inwardly, he answered: "Mandheling."

In 1945, when the Japanese Emperor announced the surrender, the soldier went home — but he never forgot that cup. He phoned a contact and asked him to buy a batch of "Mandheling" on his behalf. The man, whose name was Pwani, shipped coffee beans from the Lake Toba region of Sumatra to Japan, where they were an instant hit. And that is how Mandheling coffee traveled the world, giving rise to the tale of Sumatran Mandheling.

All of it, in the end, in the service of sharing a good cup.

FrontStreet Coffee Recommendation

If the story has you reaching for a cup, these are the FrontStreet Mandheling selections to look for.

FrontStreet PWN Indonesia Gold Mandheling. Gold Mandheling is the benchmark of top-tier Mandheling, and FrontStreet's comes from PWN in Indonesia, a company that applies unusually strict standards. Beans must be 18 mesh or larger, and a 300g green sample may contain fewer than 3 defective beans — the bar for the highest G1 grade. On top of that, the beans are hand-sorted to strip out every remaining defect, which lifts the cleanliness and the intensity of the sweetness. Those standards explain both the quality and the limited output, and they are why FrontStreet PWN Gold Mandheling stands at the top of the category. It is a wet-hulled coffee from the Aceh region, medium-dark roasted, with black chocolate and caramel flavors and Mandheling's wild herbal streak intact.

FrontStreet Lintong Mandheling. From the Lintong region around Lake Toba in North Sumatra, this is the traditional Mandheling profile. Medium-dark roasted for low acidity, it is rich and full, with a bittersweet edge and a forceful, stimulating entry. Look for clove and woody aromas, spice and mint notes, and a strong, lasting sweetness. This is the cup that the region's wet-hulled, microbially fermented processing makes possible — heavy, earthy, and herbal.

FrontStreet Classic Blend. For espresso machines, this is the blend customers come back for. It builds on the creamy, nutty character of Brazilian coffee with the addition of medium-dark Mandheling, which brings butter, roasted chestnut, and caramel to the front. The Mandheling also lifts the body of the whole cup and lends it sandalwood, herbal, and spice notes, while a small proportion of Robusta adds richness to the crema. Latte art or a layered Dirty — either is effortless.
