Indonesia has a long coffee producing history, but recently their coffees have been overlooked by the specialty market. Thanks to our innovative and ever-expanding supply chain, we are proud to bring you high-quality coffees from many of Indonesia’s unique regions, accompanied by in-depth traceability information.
Indonesia is perhaps best known for its unique wet hulling process (giling basah). Though its exact origins are unclear, wet hulling most likely originated in Aceh during the late 1970s.
Wet hulling’s popularity can be attributed to producers’ need for prompt payments. It was also adopted specifically by many producers who lacked the drying infrastructure that was needed to shelter drying parchment from the high humidity and inconsistent rainfall typical in Sumatra. At higher elevations with constant humidity and unpredictable rainfall, drying can prove to be slow, risky and difficult.
Our Trenggiling Wet Hulled is a gamechanger for Indonesian coffee production. Our efficient supply chain reduces costs to the customer and shares more profits with farmers by removing the circuitous to route export coffees have been taking.
Most people associate the name “Mandheling” with good-quality Indonesian coffees. The name suggests that that coffee was grown on Sumatra; however, it can actually be added to all coffees traded through the major port in Medan, which has been Indonesia’s main hub for trading and export for decades.
Initially, Mandheling was composed entirely of coffee produced on Sumatra, the island where Medan is located; however, as demand for this coffee increased and wet hulling was replicated across Indonesia, the supply chain became ever more complicated. While it’s difficult to know for certain, we estimate that somewhere between 70-90% of all wet-hulled coffee produced in Indonesia is exported via Medan and sold as “Sumatra Mandheling,” regardless of the island where it was actually produced. This opaque and convoluted supply path is driven by the high price the name “Mandheling” demands. Imagine: where a Flores is shipped to Sulawesi to be sold as a Toraja, only to make its way to Medan and, after a trip that can take over 4,000 kilometers, is finally exported and marketed as a Sumatra!
In an attempt to shorten the supply chain, reduce the carbon cost of transport, and deliver more transparency to the marketplace, we introduce our ‘Indonesia Trenggiling’ brand. Trenggiling is sourced through select partnerships across the Indonesian archipelago, where we can verify traceability to the point of village collector or district processor. Our team on the ground controls quality from the point of purchase through export, collaborating with regional mills, warehouses, and logistics providers to deliver the unique flavor of Indonesia, year-round, and with the freshest harvest available.
Our origin QC teams select our Trenggiling lots to deliver the unique flavors of Indonesia at accessible prices using the freshest harvest available, all year-round. Our whole-harvest sourcing and vertical integration means you can get it all at prices that ensure both producer resilience and roaster success.
Cultivation
Most farms are small. On average, farms are between 0.5 to 2.5 hectares. Coffee is usually the primary cash crop for farmers, but most also intercrop their trees alongside vegetables, maize and fruit. This intercropped produce will make up a substantial part of the family’s diet for the year.
In addition to growing coffee as a cash crop, many smallholder farmers also work at hired laborers at the nearby tea plantations. Tea is also a huge crop in the area. The bigger tea plantations are often near coffee farms. When the harvest is finished, coffee farmers will go there and pick leaves under contracted labor.
There are more and more initiatives by farmers to organize themselves into cooperatives. Individually farmers did not have When they’re in cooperatives, farmers can advocate for better prices for their cherry or parchment and cooperative members can share resources, organize trainings and negotiate better opportunities.
Harvest & Post-Harvest
Indonesia is perhaps best known for its unique wet hulling process (giling basah). Though its exact origins are unclear, wet hulling most likely originated in Aceh during the late 1970s.
Wet hulling’s popularity can be attributed to producers’ need for prompt payments. It was also adopted specifically by many producers who lacked the drying infrastructure that was needed to shelter drying parchment from the high humidity and inconsistent rainfall typical in Sumatra. At higher elevations with constant humidity and unpredictable rainfall, drying can prove to be slow, risky and difficult.
The basic process for wet hulling is as follows: Cherry is harvested and pulped at or near the farm, on small hand-cranked or motorized pulpers. The coffee is fermented overnight (in small tanks, buckets, or bags) and washed with clean water the following morning. Parchment is sun-dried for between half a day and two days, depending on the weather, to allow for skin drying which eases the removal of parchment.
At this juncture the moisture content is between 30-40% and parchment is delivered to a processor (often by the village collector) for wet hulling. A wet hulling machine is larger, requires more power, and runs at a faster speed than a traditional dry huller. After the hulling, the coffee seed is whitish and pliable and is called labu. It is laid out to dry on tarps or patios, where it reduces in size and moisture to 14-15%. This stage the green coffee is known as asalan – unsorted and with defects. Much of the internal commercial trade is for asalan. Exporters, most of whom are based in Medan, will finish the drying down to 12-13%, sort and prepare for shipment.
Small Batch Roasting: Roast For You Service – Terms & Conditions
Introduction
Small Batch Roasting now offers a service that offers personalised coffee roasting for customers who want to enjoy freshly roasted coffee tailored to their preferences. This article will discuss the Roast For You Service, its terms and conditions, and provide essential information for customers to make informed decisions when ordering.
Roast For You Service
When you choose to have your coffee roasted for you, we will roast the exact amount ordered and roast this for you to the selected roast profile you have chosen. Our small batch roasting process ensures that your coffee is roasted with care and precision, resulting in a high-quality, freshly roasted product.
Minimum Green Weight Requirement
Please be advised that the minimum green weight for roasting any one single origin is 6kg. Any orders placed with less than 6kg of each origin will be placed on hold and may cause delays in being dispatched. We will contact you to discuss how you wish to proceed in this case.
Weight Loss During Roasting
Please be mindful of the weight loss through moisture loss during roasting, which is typically between 12-20% depending on the level of roast. The darker the roast, the higher the moisture loss. This weight loss should be taken into account when ordering your coffee to ensure you receive the desired amount of roasted coffee.
Order Processing Time
Orders for roasted coffees will naturally take a little longer to process. Please allow a minimum of 3 days for your order to arrive from the point of order. If we are able to drop your order in the roasting schedule sooner, we will always endeavor to do so.
Mixed Orders
Mixed orders which include green and roasted coffees will be dispatched together when the roasted coffees are ready. We are unable to split these orders, so please consider the slightly longer delivery times when ordering mixed coffees.
Packaging
Your coffee will be bulk packed into a 6kg bulk bag with an identifying label on only. This packaging ensures that your coffee remains fresh and protected during transit.
Roast Profile and Liability
We will roast to your desired roast profile, but are unable to take any liability for any taste discrepancies that may arise from this. We are unable to take back any coffees once they have been roasted to your desired roast profile.
Yield Estimate
Typically, a medium roast coffee at 6kg green will yield 5.1kg of freshly roasted coffee. This estimate should be taken into account when ordering your coffee to ensure you receive the desired amount of roasted coffee.
