Indonesia's specialty coffee growers scene showed rapid growth for the last 5 years. Driven by young and passionate coffee growers, the local coffee industry experiences massive movement in terms of coffee growing and processing. The young generation is getting more interested in exploring the potential of Indonesian coffee through countless experimental processes. For coffee processors like Pak Aziz, he began working with anaerobic washed processes since they fit the local geography and microclimate.
Fully washed processes often exhibit clean, bright acidity, smooth texture, and high flavour clarity. It often lacks the depth of flavour normally found in honey or natural-process coffee. By incorporating anaerobic fermentation prior to being fully washed, it adds another layer of taste and flavour that makes a fully washed coffee stand out on the cupping table. This particular lot went through 72 hours of natural anaerobic fermentation before going through the normal fully washed process.
The result is a creamy texture with fine tropical fruit acidity, like pineapple The coffee significantly improved in acidity and body intensity, with much better clarity. The moderate fermentation taste gives an impression of cascara flavour, which is enjoyable for creamy and lightly aromatic coffee.
Sumatra is a blessed land, growing one of the finest arabicas in Southern Asia. What makes it even more interesting is the scale of coffee production that covers the northern and southern parts of Sumatra Island. There is a particular coffee growing region that really attracts us as coffee buyers, which often gives us the perception that coffee quality is close to Panama coffee. This tasting experience led us to buy coffee directly from Kerinci, Jambi, and West Sumatra.
Rukun Saudara Tani, established by Abdul Aziz Thohari, is no longer a stranger in the local or international specialty coffee scene. Operating at the foothills of Mount Kerinici, Rukun Saudara Tani is a small cooperative processing coffee cherries that come from smallholder farmers around Mount Kerinci. Pak Aziz is mainly responsible for monitoring coffee processing, farm management, and quality control checks.
After years of dedication, Pak Aziz finally landed his first achievement by winning the Cup of Excellence COE competition, first held in Indonesia in 2022, with lactic natural process coffee. This achievement continues with winning first place in the KKSI (local version of COE) competition in the fully washed coffee category with anaerobic washed coffee. After 4 years of working together, we are happy to keep offering the finest coffee produced by Rukun Saudara Tani.
