Indonesian Arabica Coffee Beans

Highland lots from 1,100 to 1,900 m, wet hulled, washed, or natural dried, scoring 83 to 87 points on the SCA protocol.

Arabica is the species buyers come to Indonesia for when they want character rather than volume. Our arabica grows between 1,100 and 1,900 metres on five islands, is counted at 300 g under SNI 01-2907 and SCA green grading, and scores between 83 and 87 points on the cupping table at Grade 1. Every island coffee is offered from Grade 1 to Grade 6 on one page rather than split into a product per grade, so you can compare processing methods and altitudes first and fix the grade with the contract.

  • 83 to 87 points at Grade 1

Why Indonesian arabica tastes the way it does

Two things set it apart. The first is altitude combined with equatorial rainfall, which gives long, uneven ripening and a dense bean. The second is wet hulling, the giling basah method used in Aceh and Toraja, where parchment is removed at 30 to 50% moisture instead of 11%. That single step is responsible for the swollen bluish bean, the low perceived acidity, and the heavy, savoury, cedar-and-earth cup that people mean when they say a coffee tastes Sumatran. Washed lots from Java and Kintamani, and the natural dried Bajawa lots, sit at the other end of the same catalogue.

How we grade and score arabica

Each coffee is sampled at 300 g and counted for defects, under SNI 01-2907 for the grade and under SCA green grading for the specialty figure, with screen retention measured on sieves rather than estimated. The sample is then roasted to a cupping profile, rested, and scored by two Q Graders on the SCA protocol. We publish the actual defect count and the score band, not a marketing grade, because your own cupper will check both. Grade 1 is the specialty sort; the lower grades come from the same mills and go into blend and roast programmes.

How arabica buyers usually contract

Specialty roasters take one or two islands per season, book at harvest, and hold the coffee in barrier liners to protect the cup. Blenders take the washed Java and Kintamani lots for consistency and uniform screen size. Private label buyers usually skip green entirely and contract the roasted version of the same lot. All three patterns work from the same offer list, and a container can carry more than one island if the volume per lot justifies the split.

Frequently asked questions

Ordering, samples, shipping, and payment.

What cup scores do your Indonesian arabica lots reach?

Between 83 and 87 points on the SCA cupping protocol at Grade 1, scored in house by two Q Graders. Sulawesi Toraja is usually our highest at 85 to 87, Sumatra, Bali and Flores sit at 84 to 86, and the washed Java coffees at 83 to 85. Lower grades from the same mills score below those bands and are priced for blending. Scores are re-run on the pre-shipment sample, so the figure on the contract is the figure on the coffee that ships.

Which arabica lots are wet hulled and which are washed?

Gayo from Aceh and Toraja from Sulawesi are wet hulled at 30 to 50% moisture (giling basah). Ijen in East Java and Kintamani in Bali are fully washed. Bajawa on Flores is natural dried on raised beds for 18 to 22 days.

When are Indonesian arabica harvests available for shipment?

Gayo peaks October to February, Toraja May to September, Kintamani and Bajawa May to September, and Ijen June to October. Because the islands sit on different cycles, at least one fresh crop arabica is usually available for prompt shipment. Season contracts are booked ahead of the relevant harvest, particularly on certified volume.

Are certified arabica programmes available on these lots?

Yes. Kintamani ships Organic under EU and NOP rules and Fairtrade, Toraja ships Organic, Ijen ships Rainforest Alliance and 4C, and Bajawa ships Fairtrade. Certified volume is allocated at harvest against the producer group's certificate, so book earlier than you would a conventional lot.
