🏔️ Terroir & Technical Specifications
Cultivated in the fertile volcanic highlands of the Karo Regency in North Sumatra, these trees grow alongside pristine fruit orchards. The unique high-altitude climate slows bean maturation, allowing the cherries to develop complex sugars perfectly suited for advanced processing techniques.

🍈 The ‘Wet-Hulled Melon’ Co-Fermentation Process
This exceptional coffee is defined by its experimental Wet-Hulled Melon Co-Fermentation process. It seamlessly adapts Sumatra’s historical Giling Basah (wet-hulling) technique into a controlled, flavor-infused environment.
- The “Melon” Integration: Freshly harvested, hand-picked Catimor cherries are pulped. During the overnight fermentation stage—where the remaining fruit mucilage is broken down—actual fresh melon fruit and natural juices are added to the sealed tanks. The porous coffee seeds act like natural sponges, absorbing the vibrant, sweet esters from the melon as they ferment.
- The “Wet-Hulled” Stage: Following fermentation, the beans are washed and partially sun-dried until they hit roughly 20-24% moisture. They are then immediately mechanically wet-hulled to remove their outer parchment shells while still soft and moist, giving the coffee its signature deep Sumatran body.
- The “Dairy” Finish: Because the melon fruit co-ferments with the bean’s natural sugars, it creates a lactic acid breakdown that yields an incredibly velvety, smooth, and milky mouthfeel reminiscent of a luxury milk-based dessert
🍵Why does it taste so special?
The harmony between the intense volcanic soil compounds and the melon co-fermentation elevates this cup profile beyond standard coffee boundaries, making it exceptionally clean and natural-tasting:
- Explosive Melon Sweetness: The cup opens with dominant notes of juicy honeydew melon, cantaloupe, and vanilla candy.
- Creamy Dairy Texture: An luxurious, smooth body carrying distinct structural hints of milk chocolate, vanilla cream, and buttery cashews.
- Clean, Spiced Accent: A perfectly integrated finish of brown sugar and delicate brown spices that ensures excellent structural balance.
☕ Roasting & Brewing Guidance
To protect the fragile, volatile fruit aromatics and the milk-chocolate sweetness, Karo Melon Dairy is roasted exclusively as a Filter Roast.
To extract the complex fruit layers and the creamy dairy finish, manual pour-over extraction is highly recommended:
- Brew Method: V60, Origami, or Kalita Wave.
- Recipe: 15g of medium-ground coffee to 225ml of water (1:15 ratio).
- Water Temperature: Keep your water at 91°C–94°C. A steady pour allows the sweet melon profile to shine alongside a brilliantly balanced acidity.
