Recently, Taru Wangi welcomed an international intern from ISIPCA, France, one of the world’s leading institutions for fragrance, cosmetics, and aromatic sciences.
Students at ISIPCA learn about fragrance formulation, aroma chemistry, and raw materials. But there is one part of the fragrance industry that is harder to learn in a classroom: where ingredients truly come from.
So, instead of spending most of his internship behind a desk, we introduced a different experience.
We sent him to Sulawesi.
Not to simply observe, but to spend time directly in the upstream patchouli supply chain, where cultivation, drying, and distillation happen every day.
Before long, local partner farmers gave him a nickname: Acho.

Learning Patchouli from the Source
In Sulawesi, Acho joined our farming partners to understand how patchouli oil is produced.
He learned how healthy planting materials are selected and how cultivation practices affect crop quality. He also followed the post-harvest process, from drying patchouli leaves to watching traditional steam distillation in action.
The goal was simple: to understand patchouli oil by seeing how it is made.
For many people in the fragrance industry, raw materials are often understood through specifications, GC-MS reports, and formulation performance. Yet spending time at origin offers a very different perspective.
Patchouli oil takes time to produce. Farmers spend months cultivating the crop before harvest. After that comes drying, distillation, and careful handling to preserve quality.
Behind every kilogram of patchouli oil are farming decisions, technical processes, and skilled hands.
At some point, patchouli becomes more than a fragrance ingredient. It becomes easier to understand the work, knowledge, and people involved in producing it.
Why Understanding Origin Matters

At Taru Wangi, we believe better understanding leads to better partnerships.
When people understand where patchouli oil comes from, they also better understand quality, consistency, and traceability.
This is why we continue creating opportunities for learning and industry engagement. We believe stronger connections between farmers, producers, and downstream industries help build a more transparent supply chain.
Internship and Industry Visit Opportunities
We welcome students, academics, and young professionals who want to learn more about the essential oil industry.
Participants can experience patchouli cultivation and distillation activities in Sulawesi. They can also learn about production processes, refinement, quality management, and business development at our headquarters in Yogyakarta.
We also welcome fragrance houses, brand owners, and B2B buyers interested in visiting our operations to better understand how Indonesian patchouli oil is cultivated, distilled, refined, and managed through our supply chain traceability and community farming partnerships.
Because understanding an ingredient often begins by understanding where it comes from.
