Coffee from Bali Sumatra
The traditional Giling Basah (wet-hulled) processing method sets Sumatra apart from every other origin. In this unique Indonesian technique, parchment coffee is hulled at a higher moisture content than fully washed coffees. This step, combined with Sumatra's humid climate, creates the region's hallmark profile: a syrupy body, deep spice notes, and a distinctive tea-like finish.
Produced by smallholder farmers who typically cultivate coffee on 1-2 hectare plots, this coffee is part of a long tradition of community-driven agriculture. Farmers often hand-pulp and ferment the coffee locally using simple methods passed down through generations. Many communities invest in shade-tree planting and soil stewardship to maintain long-term productivity and protect their surrounding ecosystems.
Coffee is a cornerstone crop in Sumatra, providing vital income for thousands of families across remote villages. Your subscription directly supports these farming communities and their sustainable practices.
Learn More About Coffee From Sumatra
Sumatra is one of Indonesia's premier coffee-growing regions, known worldwide for producing some of the most distinctive coffees available. The island's unique geography, volcanic soils, and humid tropical climate create ideal conditions for coffee cultivation.
The wet-hulling process (Giling Basah) is a distinctive Indonesian innovation born from necessity. In Sumatra's humid climate, traditional drying methods would take too long and risk spoilage. By removing the parchment layer earlier in the drying process, farmers adapted to their environment while accidentally creating one of coffee's most beloved flavor profiles.
Smallholder farming is the backbone of Sumatra's coffee industry. These dedicated producers, often working plots passed down through generations, maintain traditional cultivation methods while embracing sustainable practices. Hand-sorting beans twice to achieve GR1 DP status demonstrates their commitment to quality.
The remote villages where this coffee is grown rely heavily on coffee as their primary source of income. By subscribing to our Sumatra coffee, you're supporting sustainable livelihoods and helping preserve traditional coffee farming practices for future generations.

Frequently Asked Questions
Sumatra coffee is unique due to its wet-hulled (Giling Basah) processing method, which creates a distinctive flavor profile unlike any other origin. This process, combined with Sumatra's humid climate and volcanic soils, produces coffee with a syrupy body, earthy depth, and complex layers of flavor including black tea, brown spice, and citrus notes.
Wet-hulling is a traditional Indonesian processing method where the parchment layer is removed from the coffee beans while they still have higher moisture content (around 30-35%) compared to fully washed coffees (10-12%). This unique step contributes to Sumatra's signature heavy body, low acidity, and earthy, herbal characteristics.
GR1 DP stands for Grade 1, Double Picked. This is the highest quality classification for Sumatran coffee, meaning the beans have been hand-sorted twice to remove any defects. This meticulous selection process ensures you receive only premium quality beans in every bag.
Yes, Sumatra coffee is known for its low acidity, making it an excellent choice for those who prefer a smooth, mellow cup or have sensitive stomachs. The wet-hulling process and the coffee's natural characteristics create a cup that's full-bodied and earthy rather than bright and acidic.
Store your coffee in an airtight container in a cool, dark place away from direct sunlight, heat, and moisture. Avoid storing coffee in the refrigerator or freezer as condensation can affect flavor. For optimal freshness, use within 2-4 weeks of the roast date.

The earthy, herbal notes are a signature characteristic of Sumatra coffee and are highly prized by coffee enthusiasts. These flavors come from the wet-hulling process, the region's volcanic soils, and the humid climate. If you prefer brighter, fruitier coffees, you might explore African or Central American origins.
