What are the flavor and mouthfeel of Indonesian Java coffee beans? How should Indonesian Arabica Java coffee beans be brewed?

Java coffee, produced on the Indonesian island of Java, originally belonged to the Arabica coffee species. Pests and diseases forced Java, which once produced high-quality Arabica coffee, to switch to cultivating Robusta coffee due to fear of pest infestations. The treasured Arabica Java coffee subsequently disappeared from people's sight, and the immense favor and pursuit that Java coffee once enjoyed completely vanished. Indonesian coffee grading is based on defect proportions, divided into 6 levels: G1 to G6, with G1 being the highest grade. Java coffee beans are processed using the washed method.

Indonesia's Coffee Production History

Among coffee-producing countries, Indonesia is one that deserves significant attention. Indonesia is an island nation in the Indian Ocean, with its islands distributed on both sides of the equator. Among these, three islands—Java, Sumatra, and Sulawesi—produce globally important coffee. In the mid-17th century, the Dutch brought coffee trees to Ceylon (Sri Lanka) and Java in Indonesia. By the 18th century, Indonesia had become a major coffee production area, with its high-quality Arabica coffee almost entirely supplied to Europe. However, by the 19th century, coffee leaf rust that first appeared in Ceylon in 1869 also affected Indonesia. By 1877, most coffee plantations on the Indonesian islands had been destroyed by rust disease, forcing the Dutch to introduce other coffee varieties from Africa, namely Robusta coffee. This variety is more resistant to pests and diseases but is somewhat inferior in quality. Approximately 90% of Indonesian coffee is Robusta beans, about 6.8 million bags annually, with less than 10% being Arabica coffee.

At the end of the 17th century, the Dutch East India Company transplanted Arabica trees (Typica) from India to Jakarta on Java Island. Due to suitable climate and soil conditions, Arabica quickly spread to Sumatra in the northwest of Java Island and another large island in the northeast, Sulawesi. However, in the 1880s, a severe leaf rust outbreak occurred in Java, causing most Arabica plants to wither and die. The Dutch switched to the more disease-resistant Robusta variety, stabilizing Indonesia's coffee industry. To this day, Robusta remains the mainstay of Indonesian coffee, accounting for 90% of Indonesia's coffee production, distributed in low-altitude areas of Java and Bali Islands. The elegant-flavored Arabica is mainly distributed in northern Sumatra, Sulawesi, and higher altitudes on Java Island. Although it only accounts for about 10% of Indonesia's coffee production, the reputation of Mandheling, Golden Mandheling, Lake Tawar, Gayo Mountain, Ache, Sulawesi, Aged Mandheling, and Old Brown Java has made Indonesian coffee famous in the specialty coffee industry for decades, unaffected by other inferior Robusta varieties.

Flavor Profile of Java Coffee

Java's Arabica coffee has a wonderful fruity flavor, tasting of blackberry and grapefruit, making it a favorite among many coffee connoisseurs. This coffee features excellent medium purity with a crisp and refreshing mouthfeel. Its flavor is fresh and most suitable for making iced coffee in summer. When tasting this coffee, pairing it with acidic fruits like grapefruit will surely provide you with the best coffee experience.

Indonesia's main coffee bean production areas are on three islands: Java, Sumatra, and Sulawesi, all of which have volcanic terrain. Indonesian coffee beans are generally considered to have a strong aroma with low acidity, slightly reminiscent of herbal medicine and earthy notes. The Mandheling coffee produced in the mountainous regions of Sumatra is world-famous for its rich texture. Robusta beans produced on Java Island have a unique aroma and are often used as one of the components in espresso blends due to their rich oil content. Coffee from Sulawesi is rated as having a special herbal aroma, deep and clean. Notably, there is a special animal in the mountains of Indonesia called the civet cat (which has also appeared in Taiwan and is currently listed as one of the representative animals of Yangmingshan). It enables Indonesia to produce what is almost the most expensive coffee in the world—civet coffee. This cat likes to eat coffee berries, and the hard coffee beans, being indigestible, are eventually excreted. During their passage through the digestive tract, the coffee beans undergo fermentation, producing a unique and complex aroma that many food enthusiasts appreciate. However, due to extremely limited production, its price is extremely high, reaching hundreds of dollars per pound.

The bitterness and richness of Java coffee, combined with the sweet intensity of chocolate syrup, make Java coffee even more mellow and smooth.

FrontStreet Coffee's Recommended Brewing Method:

Dripper: Hario V60

Water Temperature: 88°C

Grind Size: Fuji grinder setting 4

Brewing Method: Water-to-coffee ratio 1:15, 15g coffee grounds. First pour 25g of water for a 25-second bloom. Second pour to 120g and pause. Wait until the water level in the coffee bed drops to halfway, then continue pouring slowly until reaching 225g. Extraction time around 2:00.

Analysis: Using a three-stage brewing method to clearly distinguish the front, middle, and back-end flavors of the coffee. Because the V60 has many ribs and drains relatively quickly, pausing during pouring can extend the extraction time.
