From Robotics to Roasting: Why I Left Tech for Indonesian Coffee

Ten years ago, I was hosting back-to-back online meetings, building tech products that impressed corporate boards but never touched real lives. Today, I'm sitting cross-legged on woven mats with farmers in Indonesia, creating something that brings joy to people's mornings worldwide. This isn't just another tech-to-passion career pivot story—it's about discovering that the most advanced coffee culture in the world isn't in Melbourne's laneways or Berlin's third-wave cafés, but right here in Indonesia, where farmers and roasters collaborate at the same table, revolutionizing what specialty coffee can be.

Giling Basah: The Indonesian Coffee Tradition That Changed Everything

Giling basah, Indonesia's revolutionary wet hull process, transforms necessity into art. Born in 1970s Aceh, this method removes parchment at 30-50% moisture—flipping traditional coffee processing completely.

From Sumatra's famous "Mandheling" with its syrupy body and cedar notes to Flores' emerging forest coffees, wet hulling creates Indonesia's signature jade-blue beans. Once misunderstood, today's wet-hulled coffees score 85+ in competitions.

Discover how JYN Coffee's Bajawa forest coffee represents wet hull's evolution—ancient forests meeting modern innovation. This Independence Day, taste how Indonesian farmers turned practical solutions into world-class specialty coffee.
