Flavor, Growing Region, and Brewing Parameters of Indonesia West Java Aromanis Estate Single-Origin Beans

BALI

Coffee arrived in Bali relatively late, initially growing in the Kintamani highlands. Production was severely affected when Mount Gunung Agung erupted in 1963, causing over 20,000 deaths and widespread destruction across eastern Bali. By the late 1970s and early 1980s, the government distributed Arabica seedlings to promote production, though some considered the effort limited, since roughly 80% of the island's current output is Robusta. Tourism provides the largest income source, but agriculture employs the most people, with Japan historically the largest buyer.

Java produces refined, aromatic coffee with relatively low acidity, a delicate mouthfeel, and excellent balance. Its fragrance and acidity surpass those of Sumatra and Sulawesi. Java's best plantations include Blawan, Jambit, Kayumas, and Pankur. Java Mocha coffee is a blend of Java coffee and Yemen Mocha.

Sumatra, Indonesia's second-largest island, is the center of the country's petroleum industry, and its rubber and timber are also famous exports. But Sumatra's coffee is even more remarkable, similar to Java coffee but with slightly heavier beans. Mandheling and Ankola beans are also highly valued, with the former hailed as the world's fullest-bodied coffee.

West Java Province is a first-level administrative division of Indonesia. Located in the western part of Java Island, it borders the Java Sea to the north and the Indian Ocean to the south, and includes offshore islands. Covering 46,300 square kilometers, Java has a tropical rainforest climate, hot and humid year-round. The plains along the northern coast have the highest temperatures, while mountainous regions are much cooler. High humidity often creates enervating conditions.

November to March is the northwest monsoon period, with rainy and cloudy weather; April to October is the southeast monsoon period, with more sunny days and less rainfall. Jakarta's average annual rainfall is about 1,760 millimeters (69 inches). Its average daily high is 30°C (86°F), with lows of 23°C (74°F). In the inland highlands of Tosari (altitude 1,735 meters, or 5,692 feet), the average temperature ranges from 22-8°C (72-47°F). Because volcanic ash periodically fertilizes the soil, Java's soil is very fertile.

"Aromanis" is a traditional Indonesian sweet snack made from flour and sugar. Here it is used to name this coffee, indicating that the beans have a cotton-candy-like mouthfeel. The beans come from Ciwidey and Garut in West Java. No special coffee seeds are used; it is the sun process that draws out such distinctive flavors. Of course, this flavor is not widely recognized in West Java itself.

At the estate, we tasted distinctly different Indonesian coffee.

Farmers used the simplest hot water immersion method to brew coffee from their plants for us.

Meticulous cultivation and processing

Allowed the coffee's flavor to break free from the established framework of Indonesian coffee.

Fruit sweetness, lemon fragrance, and even floral notes

Were all boldly presented across different varieties,

Truly subverting our perception of bitter, rich flavors.

Processing Method: Honey Process

Honey Process

The honey process, also called Honey Process or Miel Process, produces Honey Coffee. Plantations in Costa Rica, Panama, Guatemala, and elsewhere have adopted it. The so-called honey process refers to producing green beans that are sun-dried with the mucilage remaining. After removing the outer pulp from the coffee beans, a layer of viscous, gelatinous substance remains. Traditional washed processing would rinse it away, but due to water resource limits in some high-altitude regions, this direct drying method was developed.

Honey processing is a relatively complex, time-consuming, and difficult method. The first step is selecting high-quality fruit, then removing the pulp while keeping the parchment, which is the core of honey processing. The parchment contains abundant sugars and acids that slowly penetrate into the beans during drying. The second step is drying, the most important condition for producing high-quality beans.

The honey process lets coffee retain the cleanliness of washed processing. Although brightness decreases, sweetness and caramel notes increase. Depending on the degree of honey processing, honey coffees are divided into yellow honey, red honey, and black honey. The advantage is that it best preserves the original sweet flavors of ripe coffee fruit, giving the coffee subtle brown sugar flavors and nut sweetness, while berry flavors support a red-wine-based aroma, considered very elegant products.

Coffee beans are picked from the branches and separated from the fruit, then rinsed and immediately dried. The beans are "diserok" (stirred) every hour to ensure even drying, including at midnight. "This is very important at night because of the high humidity," said Ariyev of Transformed Coffee (August 5, 2014).

The coffee processing takes 25-26 days. Unsurprisingly, Aromanis beans cost slightly more than regular coffee. The Coffee Farmers Cooperative sells raw Aromanis green beans for 130,000-150,000 rupiah per kilogram, while Transformed Coffee offers them at a retail price of 80,000 rupiah per 200-gram package.

Sulawesi Island, located between Borneo and New Guinea, is sometimes also called Celebes. Coffee produced there has full-bodied beans and rich aroma. The best beans come from Kalossi and Rantepao in the south of the island. Among the many brands, try Celebes Kalossi coffee.

Overall, Indonesian coffee has a rich taste and mellow flavor with slightly syrupy notes and excellent acidity. Its two main export markets are Germany and Japan, which indirectly reflects the coffee's quality. What attracts consumers is the superior quality characteristic of Arabica beans. You can add milk or cream to high-quality Indonesian coffee without worrying about affecting its flavor. Indonesian coffee is divided into six grades, with AP the best, though no one is certain what those two letters actually represent.

When steamships replaced sailing ships, coffee from these islands faced the same problem as coffee from Mysore, India: consumers had grown used to journey-affected coffee and were unwilling to accept the taste of this "fresh" coffee. To solve the problem, the Indonesian government tried to imitate journey-affected coffee by "storing" beans for up to a year. Disappointingly, the flavor of this moisture-treated coffee was not widely accepted, affecting its reputation.

Indonesia's "aged" or "journey" coffee is still produced today, generally sold under brands like "Old Government," "Old Brown," and "Old Java."

Despite Indonesia producing so many acclaimed coffees, it's puzzling that local residents prefer drinking Turkish-style coffee rather than its renowned European-style coffee.

Indonesia Aromanis Estate's sun-dried beans taste unlike typical Indonesian beans. This bean has its own unique intense fruit aroma: mango, red wine, peach juice, plus plum and jackfruit, with a clean, sweet aftertaste. Cupping scores reach as high as 92 points, making it hard to believe this is a coffee bean from Indonesia. Its English name, Aromanis, means "sweet mango" in Indonesian.

In Indonesia, coffee beans gradually spread from Java Island to neighboring islands, first reaching Sulawesi in 1750, though not extending to northern Indonesia at that time. In 1888, cultivation began around Lake Toba, and it eventually spread to Lake Tawar in the Gayo region in 1924.

SUMATRA

Sumatra has three main growing areas: Aceh North District, the area slightly south of Lake Toba, and the more recently emerged islands near Mangkuraja. Smaller regions can also be traced in the following areas: Takengon and Bener Mariah in Aceh Province, and Lintong, Sidikalang, Dolok Sanggul, and Seribu Dolok around Lake Toba. Previously, beans from this region were commonly sold as "Sumatra Mandheling," though there is actually no place called Mandheling; the name comes from the local islanders' tribal name. Usually Mandheling has grade distinctions, divided into Grade 1 or Grade 2, and the grading method undoubtedly reflects cupping quality rather than the green beans themselves. Even so, I have reservations about recommending Grade 1, as this grade seems to have become overused. It is odd to divide different varieties into different batches, so most Sumatra beans are mixed from unknown varieties. Sumatra beans are exported through the port of Medan, but lingering there before export harms bean quality because of the humid climate.

Altitude: Aceh 1100-1300m, Lake Toba 1100-1600m, Mangkuraja 1100-1300m

Harvest: September - December

Varieties: Typica (including Bergandal, Sidikalang, Djember), Timtim, Ateng, Onan Gajang

JAVA

This region inherited Dutch colonial practices and customs, so it has more large coffee plantations. The four main coffee farms, covering 4,000 hectares, were previously government-owned. At that time, beans from this region enjoyed a first-class reputation, though not long ago large quantities of blend beans replaced other coffees in "Mocha-Java." Java beans stayed high-priced for a long time but saw significant price drops in the 20th century. Growing areas cover the area around Ijen volcano in eastern Java as well as the western region.

Altitude: 900-1800m

Harvest: September - September

Varieties: Typicas, Ateng, USDA

SULAWESI

Although seven major plantations supply about 5% of Sulawesi Island's production, local output is still dominated by smallholders. Most Arabica is grown at high elevations around Tana Toraja, while Kalosi in the south has become a brand name. There are two lesser-known regions: Mamasa to the west and Gowa south of Kalosi. A few particularly interesting washed-processed beans are worth exploring and highly recommended when the opportunity arises. Semi-washed processing is common in Sulawesi, and the region also produces considerable Robusta.

Altitude: Tana Toraja 1100-1800m, Mamasa 1300-1700m, Gowa average 850m

Harvest: May - November

Varieties: S795, Typicas, Ateng

FLORES

Flores is a small island about 320 kilometers (200 miles) east of Bali, one of the Indonesian archipelago. Joining the coffee industry relatively late, it has developed a good reputation for cultivation. In the past, much of Flores's coffee production went to domestic consumption or was mixed with other coffees for export, and it was rarely sold directly under the name "Flores coffee." The island has active and dormant volcanoes, and the mixture from Bajawa volcano has had extremely positive effects in the main growing areas. In processing, semi-washed processing is the most common, with some beans still produced using fully washed processing.

Altitude: Tana Toraja 1200-1800m, Mamasa 1300-1700m, Gowa average 850m

Harvest: May - September

Varieties: Typicas, Ateng, Robusta

FrontStreet Coffee Recommendation

If West Java's wild, fruit-forward Indonesian character surprises you, the other side of Indonesia is the classic deep, full-bodied cup. FrontStreet Coffee's PWN Golden Mandheling is the benchmark. Sourced from the Indonesian company PWN, it is selected from beans of 18 screen size and above, with fewer than three defective beans per 300-gram green sample to meet the top G1 standard, then hand-sorted three times to remove defects entirely, which lifts both cleanliness and sweetness. It is uniform, plump, and large with a low defect rate, and after a medium-dark roast it carries rich roasted aroma, a clean cup, and a full body, ideal for anyone who dislikes acidic coffee.

For the traditional Mandheling growing area, FrontStreet Coffee's Lindong Mandheling comes from around Lake Toba in North Sumatra. The region has diverse plant species, a suitable growing altitude, and the local wet-hulled method plus microbial fermentation, producing the mysterious, distinctive Mandheling flavor: intense aroma, thick body, and a strong taste. Expect clove, woody aromatics, low acidity, spicy and minty notes, and a strong, lasting sweetness.
