How Should You Brew Golden Mandheling at Home?

A three-pour schedule keeps the bed even. The goal is a clean, full-bodied cup with caramel sweetness instead of burnt bitterness or a thin body.

The name comes from the Mandailing people of Sumatra, a transliteration that spread after the Second World War.

Adjust grind finer for more body and coarser for clarity, and keep water temperature just below boiling to protect the sweet notes.

Among Indonesian coffees, Mandheling is basically the signature star. Mention these three characters, and many people directly equate them with the quality of Indonesian beans. Front Street currently also lists Mandheling as the only representative of Indonesian beans, and its flavor profile leans toward intense chocolate and nut notes, with the most captivating part being that thick, full mouthfeel that is hard to replicate in coffees from elsewhere.

However, some friends have never quite understood: why is Mandheling called "Mandheling"? What origin lies behind this? Today Front Street will tell this story.

"Mandheling" is actually a transliteration of the Indonesian Mandailing people. During World War II, when Japan occupied Indonesia, a Japanese soldier drank a cup of aromatic coffee in a café and asked the owner what kind of coffee it was. The owner mistakenly thought the other person was asking where he was from, so he answered: Mandailing. After the war ended, the soldier recalled the "Mandheling" he had drunk in Indonesia, so he asked someone to ship 15 tons of coffee from Indonesia to Japan, and it turned out to be hugely popular. Thus the name Mandheling spread.

Mandheling coffee is regarded by many as one of the most full-bodied coffees in the world. When tasting, the tip of the tongue can feel an obvious smoothness, and the acidity is low, but this acidity does not disappear completely; it can still be clearly felt—a lively touch of mild acidity interwoven with rich aroma, letting one easily experience a bit of liveliness within a gentle and fragrant whole. In addition, this coffee also carries a faint earthy note, which some also describe as an herbal plant aroma.

Golden Mandheling is not a grade, but a trademark registered by the Indonesian company N.V. Pawani Medan, abbreviated as PWN. The company was founded in 1957 and deals in the export of Indonesian products such as coffee, rubber, cinnamon, cloves, and patchouli oil. It was the first company in Indonesia to export coffee from North Sumatra, and also the earliest company to make the name "Mandheling coffee" famous in Japan. Since 1977, the company has focused on exporting high-quality coffee beans, including Sumatra Arabica coffee Mandheling Grade 1 and Robusta coffee AP-I Grade 2, mainly sold to Japan, Taiwan, China, and the United States, with exports to Japan and Taiwan, China accounting for more than 95%. In Japan and Taiwan, China, "PWN" is almost synonymous with "quality assurance." N.V. Pawani Medan holds the "Golden Mandheling" trademark, so Japanese companies had to register the separate trademark "Gold Top Mandheling." Mandheling refers to semi-washed or natural beans from the hilly area of Lintong at 900-1200 meters above sea level on the southwestern shore around Lake Toba in north-central Sumatra; Front Street Golden Mandheling undergoes four rounds of hand sorting, is one grade higher than ordinary Mandheling, and also has larger beans; the uniform and consistent bean appearance of Golden Mandheling also drove another wave of market demand, and even Europe and America became fascinated by it.

Precisely because Front Street Golden Mandheling is outstanding in quality, its price is also considerably higher than ordinary Mandheling, which is also why many fake Golden Mandhelings appear on the market.

Front Street believes that truly authentic Golden Mandheling must be a product of the Indonesian PWN coffee company (the Golden Mandheling trademark belongs to PWN). When importing Golden Mandheling green coffee beans, a PWN company certificate of authentication is attached (used to identify authenticity). If the seller cannot provide source information for the Golden Mandheling green beans (certificate or jute bag), then you should be extra cautious.

Front Street Golden Mandheling coffee beans are produced in the Gayo Mountains of Aceh, Grade G1, and undergo 3 rounds of hand sorting to ensure large, plump beans (19 screen size) with few defects. It presents a very clean, full-bodied mouthfeel and high sweetness, and is a representative of high-quality Mandheling coffee.

So how should Front Street Golden Mandheling coffee be brewed to taste good?

Front Street's brewing approach for Mandheling coffee is: to express a full-bodied yet clean mouthfeel, highlight caramel, chocolate, and its signature herbal aroma, while trying as much as possible to avoid unpleasant bitterness. Next, Front Street will explain from equipment selection and important brewing parameters, using Front Street Golden Mandheling for the demonstration.

Front Street recommends brewing with freshly roasted coffee beans, as only then can you experience the coffee's rich flavors to the greatest extent. The coffee beans shipped by Front Street Coffee (FrontStreet Coffee) are all within 5 days of the roasting date, because Front Street is very clear about how much bean freshness affects flavor. Front Street's roasting principle is "freshly roasted good coffee," so that every customer who places an order receives the freshest possible state when the coffee arrives. The resting period for coffee is about 4-7 days, so when customers receive it, it is exactly at its best flavor.

For the dripper, Front Street chose the Kono Meimon dripper. The biggest feature of the Kono dripper is that the ribs extend from the bottom to the middle, while the upper part is a smooth dripper wall. In this way, after the filter paper fits the dripper, water cannot "secretly" bypass the coffee grounds and slip away, which helps improve the fullness of the mouthfeel.

The dose Front Street uses is still 15g. More coffee powder is not necessarily better, nor is less necessarily better; it specifically depends on the dripper size. Front Street uses a 1-2 cup dripper, and a dose of 15-20g is within a reasonable brewing range. Brewing outside this range will be relatively difficult.

For the coffee-to-water ratio, Front Street recommends 1:15. Although some may suggest 1:13 or an even smaller coffee-to-water ratio, Front Street mentioned in previous articles that concentration and fullness are not necessarily related, and being too concentrated can make people uncomfortable. Therefore, using a 1:15 coffee-to-water ratio can also very well present Mandheling's full-bodied mouthfeel.

For grind size, Front Street uses a coarseness with a 70% passing rate on a No. 20 sieve. When brewing Front Street Golden Mandheling, the grind size should be a bit coarser than for light-roast coffee beans, because Front Street Golden Mandheling is dark roasted, with a looser structure and easier absorption and release of coffee substances. If it is ground to the coarseness of light-roast beans, it is easy to brew out burnt bitterness; if it is ground coarser, the coffee will become thin and tasteless, with a mouthfeel as thin as water.

For water temperature, Front Street recommends brewing with 87-88°C water. The reasoning is the same as for grind size: too high a water temperature easily produces burnt bitterness, while too low a water temperature makes the coffee flat and can also produce unpleasant sour, spoiled notes.

The brewing method uses three-stage pouring. Dividing it into three stages can better show Front Street Golden Mandheling's full-bodied mouthfeel and caramel sweetness. The specific water distribution is: the first stage is 30ml for blooming, which should wet all the coffee grounds and allow degassing, preparing for better extraction of flavor substances afterward; the second stage pours 100ml; the final stage pours 95ml, used to increase the coffee's sweetness.

The Front Street Golden Mandheling coffee brewed this way shows an overall thick, full-bodied mouthfeel, along with caramel sweetness and chocolate, nut flavors.
