Putra Siregar — Head of Sourcing for Indonesia Specialty Coffee, leading lot selection from supplier to Medan warehouse.
Putra grew up in North Sumatra, surrounded by the coffee logistics flowing in and out of Medan. He spent ten years working with cooperative groups across Lintong, Mandailing, and the Aceh Gayo highlands before joining Indonesia Specialty Coffee's sourcing team.
His expertise sits at the intersection of origin knowledge and grade discipline — he can read a lot's elevation, processing method, and screen size from a single cup, then negotiate the price tier that fits both buyer and farmer. "A sourcing decision is a relationship. Not a transaction."
His writing on specialtycoffee.id focuses on what most buyers underestimate — price benchmarks per kg across grades, regional flavor distinctions, and the structural differences between Lintong, Mandheling, Gayo, and Bali Kintamani profiles.
From the plantation walk to the dry mill — the day-to-day reference points behind every lot selection.
