Flavor Profile Characteristics and Differences of Lintong Golden Aged Tiger Mandheling Coffee Beans

The Differences in Mandheling Coffee

Mandheling is a single-origin coffee often found in coffee shops. Do you know where it comes from, or why it is called "Mandheling"? Today, let's get to know Mandheling coffee together.

Mandheling coffee comes from northern Sumatra, in the western part of Indonesia. In the 18th century, to break the Arab monopoly on the coffee trade, the Dutch East India Company began experimenting with coffee cultivation in what was then the Dutch colony of Indonesia, gradually covering many islands including Java, Bali, Sumatra and Sulawesi. Indonesia sits near the equator and has more volcanoes than any other country in the world. Its suitable geography and fertile soil make it perfect for growing coffee.

In fact, most Indonesian coffee is Robusta, but that has not stopped Indonesia from securing a place in the world's specialty coffee scene — and that is all thanks to Mandheling. The main producing areas of Mandheling are Java, Sulawesi and Sumatra.

Golden Mandheling

Golden Mandheling comes from Lake Tawa near Mount Gayo in northwestern Sumatra. The Japanese especially love this bean, and very strict screening standards have been applied to it. After an initial pass through density and color sorting machines, the beans go through four additional rounds of hand selection until they are uniform in size, glossy and consistent in shape. Legend has it that the name Golden Mandheling comes from the yellowish color the green beans show in sunlight, which is why they are also called "Yellow Mandheling."

Early on, the Indonesian company Pwani Coffee Company, which partnered with Japanese firms, registered "Gold Mandheling" as a trademark.

Tiger Mandheling

The Tiger Mandheling selected by FrontStreet Coffee is produced at the Tiger Estate in Sumatra, Indonesia, which is why it is also called "Mandheling Tiger" or "Sumatra Tiger Mandheling." Northern Sumatra is relatively high in elevation, and Aceh Province, where Lake Tawa lies, and North Sumatra, where Lake Toba sits, are the main Arabica producing regions. The requirement for Tiger Mandheling is that it must carry the aroma of traditional herbal medicine, and only Mandheling beans above 17 mesh with a defect rate below 4% may be called Tiger Mandheling.

Aged Mandheling

Aged Mandheling green beans must undergo proper processing and long-term storage.

Lintong Mandheling

Lintong Mandheling is what we commonly mean by Mandheling. It generally uses the semi-washed method, also known as wet-hulling, which gives it low acidity and high body. Lintong Mandheling green beans are commonly known as "goat hoof beans." That is because with wet-hulling, the semi-hard, semi-soft moist green beans bruise easily when the mucilage and parchment layers are removed. The injured beans split open like goat hooves, creating a very distinctive shape.

The Differences Between Mandheling and Golden Mandheling:

Golden Mandheling is relatively cleaner and richer than regular Mandheling, which is tied to its roast level.

Its sugary sweet aroma is more intense, and its fruit acidity is brighter and more elegant. Generally speaking, Lintong Mandheling is best roasted until after the second crack to effectively reduce off-flavors, but Golden Mandheling maintains good clarity and sweetness whether it is finished before or after the second crack, which leaves more room for roasting interpretation.

FrontStreet Coffee Recommendation

The distinction that matters most here is between Golden Mandheling and everyday Lintong Mandheling, and FrontStreet carries both. The FrontStreet PWN Golden Mandheling is screened to 18 mesh and must show fewer than 3 defective beans per 300g green sample to meet the top G1 standard, after which it is hand-sorted three times to remove every remaining defect. That is what sharpens its cleanliness and its intensity of sweetness, and it is a large part of why supplies are limited.

For the wet-hulled character that defines Mandheling in the first place, the FrontStreet Lintong Mandheling comes from the Lintong district around Lake Toba in North Sumatra and is roasted medium-dark: low in acidity, full-bodied and bittersweet, with clove, woody and spice notes, a minty, herbal edge and a strong, lasting, thick sweetness. Both are wet-hulled, so both show the earthy, herbal depth that the process creates; the Golden Mandheling simply adds a level of cleanliness and sweetness on top.
