Meet Asman Arianto - The Man Behind the Coffee

The soul of any coffee is imprinted by the passion and dedication of those who nurture it from seed to cup. Asman Arianto, the visionary founder of the Ribang Gayo Musara Cooperative, has poured his heart and soul into this extraordinary coffee. Arianto's unwavering commitment to ensuring farmers receive fair prices, coupled with his keen eye for quality, lays the foundation for a coffee experience that is as unique and inspiring as the man who orchestrated its creation.

Ribang Gayo Musara Cooperative - Empowerment and Sustainable Growth

At the heart of the Sumatra Gayo Coffee story is the Ribang Gayo Musara Cooperative. With over 350 members, it's a catalyst for community growth, development, and sustainability.

Ensuring fair wage for coffee pickers is a cornerstone of the cooperative. Regardless of global coffee market flux, members receive stable, above-average pay, promoting quality in every bean harvested.

Premiums from superior coffee sales are reinvested into the community, enhancing farming equipment, processing facilities, or advancing agricultural education and training.

The cooperative also champions continual learning, fostering knowledge exchange and innovation. Improved practices lead to superior beans, higher premiums, and further community investment. 

By prioritizing its people and coffee quality, the cooperative shapes a brighter future for Sumatran coffee, serving as a blueprint for others to follow.


The Cultural Influence - How the Sumatran Region and Processing Methods Shape the Coffee

Situated in the verdant landscapes of Indonesia, the Sumatran region confers a distinct character upon every coffee bean cultivated within its borders. This unique profile is a product of not just the area's unique climate and volcanic soils, but also of cultural heritage deeply rooted in coffee cultivation. Traditional techniques passed down through generations merge seamlessly with innovative practices such as transitioning from the local wet-hulled method to fully washed processing.

Historically, Sumatran farmers employed a method known as wet hulling or "Giling Basah." This technique, renowned for creating coffee with earthy, spicy flavors and a full body, involved removing the coffee bean's parchment layer when still damp, post a brief drying period to bring the moisture down to about 30 to 35%. However, wet hulling often led to inconsistent quality and potential damage to the coffee beans due to early parchment removal.

Asman Arianto, challenging tradition for the sake of quality, adopted the fully washed processing method for his Sumatra Gayo Coffee. By fermenting the beans in water tanks, thoroughly washing away any residual fruit, and allowing for slow drying before the final hulling, this method presents cleaner, brighter, and more consistent flavors. 

This shift in processing also symbolizes a wider cultural transition - an inclination towards embracing new techniques to enhance quality while preserving the core heritage. Local festivals celebrating the harvest and cooperative learning between farmers further enrich this cultural tapestry. Since this shift has occurred, it feels like the curtains have been lifted, revealing the stunning coffees that were once hidden.
