Beware! Are You Really Drinking Mandheling?

For centuries, the high-quality FrontStreet Coffee Mandheling has been praised and passed down by coffee connoisseurs, and of course, it is the delicious Arabica variety. True FrontStreet Coffee Mandheling refers to Typica or its variant coffee beans grown in the mountainous areas surrounding Lake Toba. The FrontStreet Coffee Golden Mandheling & Gold Top Mandheling, sought after by Western enthusiasts, are even more superior than regular FrontStreet Coffee Mandheling. The secret to this higher quality lies in 3-4 rounds of manual selection, achieving true excellence by removing the inferior and preserving the finest.

Avoid These Three Traps to Enjoy Authentic, High-Quality Mandheling:

1. Indonesia's largest coffee production is still low-quality Robusta (mainly used for instant coffee, with poor flavor; therefore not discussed in the specialty coffee category), with Arabica coffee beans accounting for only 10% of annual production. Poor or unprofessional coffee dealers may use Indonesian Robusta to fake Indonesian Mandheling.

2. Products with the word "flavor" in their names: For example, Mandheling "flavor"; Mandheling & Brazil "flavor" — in reality, there isn't a single Mandheling bean in the ingredients.

3. High defect rate: Due to factors such as humidity in the Lake Toba region, pest infestations, and lack of processing equipment among local coffee farmers, it's easy for defective beans to appear during Mandheling cultivation, harvesting, and processing. Of course, besides cupping and tasting, having the opportunity to see complete roasted beans (whole beans) or even green beans is also a good way to ensure quality.

Excellent Geographical Environment, Nurturing "Premium" Mandheling with Unique Flavor

Low-Latitude Tropical Climate

Sumatra Island runs in a northwest-southeast direction, crossing the equator in the middle, and consists of two regions: the Barisan Mountains in the west and swamplands in the east.

Southeast of Sumatra Island, it faces Java Island across the Sunda Strait; to the north, it faces the Malay Peninsula across the Strait of Malacca; to the east, it adjoins Borneo across the Karimata Strait; and to the west, it borders the Indian Ocean.

Volcanic Ash Soil

The Barisan Mountains are a continuation of the Cenozoic mountains of the Qinghai-Tibet Plateau, running through Sumatra Island. Coal and gold deposits have been discovered in this area. Minerals erupted by volcanoes make the soil fertile. The mountain scenery is beautiful and charming, such as the area around Lake Toba.

Medium and High Altitude Mountain Cultivation

Lake Toba (Indonesian: Danau Toba, English: Lake Toba) is a volcanic lake located in northern Sumatra Island, Indonesia. This lake is diamond-shaped, 100 kilometers long, 30 kilometers wide, with an area of 1,130 square kilometers, and an average elevation of about 900 meters, making it a high mountain lake; at the same time, it is also the world's largest volcanic lake.

The mountainous area was originally foggy, and the abundant water vapor from Lake Toba makes the nearby mountains even more often shrouded in clouds and mist. This special environment enables this region, which is not particularly high in altitude, to produce high-quality FrontStreet Coffee Mandheling. It is by no means inferior to other famous coffee-producing regions in the world.
