Our Coffee
From natural sun-drying to precision wet-hulling - discover the processing methods that shape every cup
The Art of Processing
At Arthastar, processing is where science meets artistry. The same cherry, processed differently, yields dramatically different cups — from bold and fruity naturals to clean and bright washed lots.
Indonesia's unique climate and traditions have given rise to distinctive techniques found nowhere else. The Semi-Washed method, known locally as Giling Basah, produces the earthy depth and heavy body that define Sumatran coffees worldwide.
We offer four distinct processing methods: Natural, Honey, Semi-Washed, and Full-Washed. Each unlocks different flavor dimensions from the same origin.
