As specialty coffee becomes increasingly popular, more and more coffee enthusiasts are starting to try pour-over at home. However, pour-over is not something you can succeed at by simply copying a recipe; it requires repeated brewing to build up feel in order to produce consistently. In this article, Front Street Coffee (FrontStreet Coffee) will guide everyone step by step through the key points of home pour-over. In terms of bean selection, Front Street Coffee (FrontStreet Coffee) believes that Front Street Indonesia Mandheling coffee beans are more suitable as entry-level practice beans, so the following will use Front Street Indonesia Golden Mandheling as an example for explanation.

Indonesian Mandheling coffee producing regions

Front Street Coffee (FrontStreet Coffee) has mentioned many times in previous articles that the flavor of coffee beans is mainly determined by three major factors: producing region, variety, and processing method. The following will discuss Front Street Mandheling coffee around these three points. Mandheling's producing regions are concentrated on the island of Sumatra in Indonesia. This island is Indonesia's largest island, located around the equator with a typical tropical rainforest climate, high temperatures, high humidity, and abundant rainfall, providing good conditions for the growth of high-quality Arabica coffee.

However, Indonesia's producing regions are generally limited in altitude, and there is not an abundance of plots suitable for growing high-quality Arabica. Of the coffee beans produced in Indonesia, only about 25% are Arabica, because Arabica can only display its best flavor when planted at high altitudes; the remaining approximately 75% is Robusta, which can survive even at low altitudes. Sumatra happens to be Indonesia's highest-altitude region.

Among the traditional Arabica produced in northern Sumatra, the highest quality ones enter the market under the name Lintong Mandheling. Strictly speaking, Lintong Mandheling refers to coffee grown in a small area in the southwestern part of Toba in the Lintong administrative region.

Sumatra coffee bean producing regions

Mandheling coffee is also called "Sumatra coffee." Most producing regions in North Sumatra belong to the Gayo region, mainly with the Ateng variety. Coffee produced around Lake Tawar at the northern tip can be called Aceh coffee or Tawar Lake coffee; Lintong in South Sumatra and the area around Lake Toba can be called Mandheling, and the Lintong area is the core producing region of Mandheling. There are four recognized best Mandheling varieties: Sidikalang, Bergendar, Siborong Borong, and Telok Sanggul.

Lake Toba: Located in the central part of North Sumatra Province, Dutch colonists moved "Java Mandheling" north to the Lake Toba area in 1888, creating the legend of modern Mandheling.

Lake Tawar: Located in the central part of the Aceh Special Region, at the northern tip of Sumatra Island, with an area less than one-tenth of Lake Toba. But in recent years, its coffee quality and production have surpassed Lake Toba.

Gayo Mountains: Located in the Aceh producing region of North Sumatra Province, local coffee farmers are mostly indigenous farmers. The word "Gayo" originates from a tribe in the Aceh region of Indonesia. This area has ideal growing conditions, a long history and culture, unique flavor, and widely adopts organic farming methods without chemical fertilizers. It is regarded as a world green coffee production region, so Gayo coffee is also often called green coffee or Gayo organic coffee.

Indonesian Mandheling coffee processing method

When talking about Indonesian coffee, one cannot fail to mention the processing method that made Mandheling famous worldwide — wet-hulling. Interestingly, this green bean processing method is not a helpless move by locals under the influence of weather, but it is precisely this that gives Mandheling its unique earthy, herbal, and spicy notes.

When using the wet-hulling method, the semi-hard, semi-soft moist green beans are easily crushed during the process of removing the mucilage and parchment layer, and the bean body cracks open in a sheep's hoof shape, commonly known as sheep's hoof beans. Front Street Coffee (FrontStreet Coffee) considers this a very distinctive feature of Mandheling and does not count it as a defective bean.

The origin of Indonesia's wet-hulling method

According to Front Street Coffee (FrontStreet Coffee), the reason Indonesia uses the wet-hulling method to process coffee cherries is that the local area is rainy and typhoon-prone, making it difficult to meet the good weather required for sun-drying; at the same time, local economic conditions are limited, and they cannot afford the higher cost of the washed method, so this highly local processing method came into being.

Of course, today's Indonesian coffee industry is no longer the impoverished scene of the past. There are quite a few estates and companies with the ability and conditions to use the washed method, but wet-hulling has still not been abandoned. Front Street Coffee (FrontStreet Coffee) believes that wet-hulling is the factor that made Mandheling known to the world. Whenever Mandheling is mentioned, wet-hulling comes to mind, and the two have clearly formed a mutually complementary relationship.

The specific steps of the wet-hulling method can be divided into the following two stages:

In the first stage, the skin and pulp are removed with a wooden pulper, followed by 3 hours of fermentation and then drying, bringing the moisture content down to 30-50%, which is semi-dry and semi-wet. In the second stage, the mucilage and parchment layer are removed, and drying continues in the later stage. The drying process takes 2-4 days, and the moisture content drops to 12-13%.

What is "Golden Mandheling"?

When it comes to "Golden Mandheling," we must start with PWN. This abbreviation often appears alongside the name Mandheling coffee. It is actually the abbreviation of a company — Pwani Coffee Company.

This company is very famous locally in Indonesia, mainly engaged in purchasing Mandheling coffee. Almost all of Indonesia's best producing regions have been taken under its wing, so most beans produced by PWN are unique specialty products. Golden Mandheling is precisely a product produced by this company. After the green beans are purchased, they must undergo multiple rounds of manual hand-sorting to pick out plump, flawless beans. Only these excellent beans, as if having gone through layer after layer of selection, can be classified as Golden Mandheling.

However, PWN Company has registered Golden Mandheling as a trademark, which means that from now on, only Golden Mandheling produced by PWN Company can be considered truly Front Street "Golden Mandheling." Many beans on the market that are not produced by PWN Company but bear the Golden Mandheling name should actually be called specialty Mandheling.

So how should Front Street Golden Mandheling coffee beans be brewed as pour-over? Front Street Coffee (FrontStreet Coffee) will now share with coffee-loving friends.

What equipment is needed to prepare pour-over coffee?

Pour-over coffee naturally cannot do without corresponding equipment. What exactly is needed? Front Street Coffee (FrontStreet Coffee) will now list them one by one for coffee-loving friends.

1. Pour-over kettle: Pour-over kettles on the market vary in size and material, and can be chosen according to needs. What affects the brewing result more is the size of the spout, because it relates to the flow rate. Beginners are generally advised to use a fine-spout kettle, which is easier to control. In addition, each type of pour-over kettle is suitable for a different heating method (induction cooker or gas stove), so special attention should be paid when purchasing.

2. Dripper: Drippers also vary in size and material, mainly divided into three shapes: fan-shaped, cone-shaped, and wave-shaped. The size of the dripper's bottom opening affects the flow rate of coffee extraction, which in turn affects the flavor. The fan-shaped dripper has a small opening and slow flow rate, giving a mellower taste; the cone-shaped dripper has a large opening and fast flow rate, giving a lighter taste; the wave-shaped dripper has a flat bottom and, paired with special wave-shaped filter paper, produces the most even-tasting coffee. More unusual is the metal mesh dripper, which requires no filter paper and can retain more coffee oils for a richer taste, but some finer coffee grounds may not be filtered out.

3. Filter paper: Filter paper comes in bleached and unbleached types. Bleached filter paper looks whiter, while unbleached filter paper is closer to light brown. The function of filter paper is to use its extremely dense fibers to hold the ground coffee and filter the extracted coffee into the cup. When buying filter paper, you should choose the corresponding model according to your own dripper.

4. Grinder: Good pour-over coffee requires a good grinder. There are three types of grinders on the market. 1) Ghost tooth grinder 2) Flat burr grinder 3) Conical burr grinder

5. Thermometer: A thermometer is used to measure the water temperature for coffee. Thermometers on the market include Tiamo thermometer, Hero thermometer, and Cafede Kona thermometer.

6. Electronic scale: An electronic scale allows us to better control the coffee-to-water ratio when brewing coffee, reducing unstable factors and increasing ample fault tolerance. Electronic scales range from several hundred yuan each to as low as several dozen yuan each, including Acaia electronic scales, Hero smart scales, and Timemore electronic scales.

7. Powder sifting mesh: Mainly used to judge grind size. Each coffee bean has a different suitable grind size for pour-over. Through continuous testing, Front Street Coffee (FrontStreet Coffee) has determined that a grind size with 80% passing through China standard No. 20 sieve is suitable for pour-over.

What are the detailed steps for pour-over coffee?

1. Water temperature

The higher the water temperature, the stronger the extraction ability, the more bitter the coffee, and the more intense the taste; the lower the water temperature, the weaker the extraction ability, the coffee is prone to becoming sour, and the taste is mild and light. Pour-over temperature should be adjusted according to the coffee's roast level. Light-medium roast beans are recommended at 90-91°C, and medium-dark roast beans at 86-88°C. Front Street Coffee (FrontStreet Coffee) basically adjusts within this range. A customer once questioned this brewing temperature, so Front Street Coffee (FrontStreet Coffee) took Front Street Golden Mandheling coffee beans (dark roast) and brewed them at 90°C water temperature, and the result was a taste almost "comparable" to espresso.

2. Grind size

This refers to the size of coffee particles. Grind size affects the contact time between coffee and water. The finer the coffee grounds, the more substances water can extract in the same amount of time, but with a fine grind, over-extraction is easy during the brewing process; conversely, the coarser the coffee grind, the fewer substances are extracted in the same amount of time, but with a coarser grind, under-extraction is more likely. Front Street Coffee (FrontStreet Coffee) recommends using a grind size with 80% passing through China standard No. 20 sieve as the pour-over grind size, which was determined through many taste tests. It should be noted that different coffee beans have different grind sizes, so when the pour-over flavor seems off, you can check whether the grind size is the problem.

3. Coffee-to-water ratio

The coffee-to-water ratio refers to the ratio of coffee grounds to brewing water, affecting the strength of the coffee. It can be 1:10, 1:13, 1:15, or 1:16. Front Street Coffee (FrontStreet Coffee) recommends using a 1:15 coffee-to-water ratio, which is relatively moderate in both strength and taste. Of course, everyone pursues a different coffee taste. When extracting coffee, everyone can adjust their own coffee-to-water ratio according to the strength and taste they want.

Next, Front Street Coffee (FrontStreet Coffee) will share the specific parameters for brewing Front Street PWN Golden Mandheling coffee beans as pour-over.

[Front Street Coffee (FrontStreet Coffee) PWN Golden Mandheling coffee brewing recommendations]

Dripper: KONO Coffee dose: 15g Coffee-to-water ratio: 1:15 Water temperature: 86-87°C Grind size: 70% passing through No. 20 sieve

Front Street PWN Golden Mandheling coffee brewing technique: staged extraction.

In the first stage, pour 30g of water for a 30-second bloom. In the second stage, pour in a slow circular motion until reaching 125g, then pause. When the water level drops and is about to expose the coffee bed, continue pouring in the third stage until reaching 225g and stop. When the water level drops and is about to expose the coffee bed again, remove the dripper. (Timing starts from the beginning of the bloom.) The extraction time is 2'00".

Front Street PWN Golden Mandheling flavor: Layered and varied, mellow and clean, high balance, rich nut and caramel aromas, with chocolate notes, and a lingering finish.
