Gayo Jumbo 18 Up is a premium Arabica coffee from the Gayo Highlands, Aceh, graded at screen size 18 and above. The ≥18 screen classification means the beans measure at least 7.14 mm in diameter. This large size ensures visual uniformity and stable roasting performance.

Where Does Gayo Jumbo 18 Up Grow?

Gayo Jumbo 18 Up grows at 1,200–1,700 meters above sea level in the Aceh Highlands. Farmers cultivate the coffee in volcanic soil with temperatures between 13–28°C and annual rainfall of 1,500–3,000 mm. These environmental factors slow cherry maturation and improve sugar development.

How Does Terroir Influence Its Flavor?

High altitude slows bean development and increases density. Volcanic soil supplies minerals that influence aroma and body. The nine-month maturation cycle allows cherries to accumulate natural sweetness. This process supports clarity, balance, and structured acidity in the final cup.

What Aroma and Flavor Profile Does It Offer?

Gayo Jumbo 18 Up delivers a fresh almond fragrance with nutty sweetness. The flavor shows herbal notes, soft fruit hints, and light spice. Medium acidity provides structure without sharpness. The body ranges from medium to high, creating a smooth and consistent mouthfeel.

What Are the Technical Specifications?

The coffee maintains a moisture content of up to 13%, which protects stability during storage and roasting. Defect count is limited to a maximum of 11, and triage value does not exceed 6. These standards align with Indonesian export-grade Arabica requirements.

How Do Farmers Harvest and Process It?

Farmers use selective hand-picking and controlled mechanical support to collect ripe cherries. The beans undergo a semi-washed process, commonly associated with Indonesia’s wet-hulled method. This process enhances body, preserves sweetness, and produces a clean, structured cup profile.

How Does It Perform in Roasting and Brewing?

The large bean size supports even heat distribution during roasting. Uniform density reduces uneven development risk. In brewing, the coffee performs well in filter, espresso, and manual methods. The cup expresses balanced acidity, subtle chocolate undertones, and a smooth finish.
