Where do you think the 100 g coffee comes from?
The 10 g cup is Burundi Nemba — that one is already known. This question is about the main 100 g cup.
Name the origin.

The thinking behind this pairing.
These two coffees were chosen for their surface similarity — both lean toward sweetness and fruit, both sit in a tonal register that surprises on first sip. Placed side by side, they create a meaningful comparison: coffees from very different places, sharing a character, yet arriving there through different trees, different altitudes, and different processing traditions. The pairing is also an exercise in assumption. Honey-processed Gayo often expresses something that doesn't match the regional expectation most people carry for Indonesian coffee. Burundi Nemba is there to highlight that surprise.
Both coffees land in the medium-to-full body range. Both carry sweetness as a defining character — though it reads differently in each cup. Both have a quality of restraint: no sharp edges, no single aggressive note dominating. They are each, in their own way, coffees that ask you to slow down. The similarity is real enough to confuse, and meaningful enough to teach.
Honey processing retains mucilage on the bean during drying, allowing natural fruit sugars to transfer into the seed. The result is a cup that reads as tropical fruit, stone fruit, or berry — notes typically associated with East African washed coffees. Gayo 1 and Gayo 3 varieties have light cellular structures that absorb these sugars cleanly. Add high altitude at 1,600 MASL, cool nights, and slow cherry maturation, and you get a cup that consistently confounds expectation.
Acidity is the clearest dividing line. Burundi Nemba, fully water-washed, retains a bright citric acidity — structured, clean, and immediate. Pantan Sile's acidity is softer, rounded, sitting quietly behind the sweetness. The texture also differs: Pantan carries a syrupy mouthfeel typical of honey-processed Gayo. Burundi sits lighter, more delicate. If you could place them on a scale — Pantan leans warm, Burundi leans bright.
