NATCHA Lots
Exotic & Rare releases developed around origin, processing and cup character.
The company behind NATCHA
A West Java coffee company built around processing, product development and long-term buyer relationships.

PT Teknologi Solusi Jaya Abadi works at the point where coffee origin, processing discipline and market application meet.
The company is headquartered in Bandung, with processing facilities in Pangalengan, Kabupaten Bandung. Its work covers controlled post-harvest processing, distinctive cup development and the creation of finished coffee formats.
NATCHA is the company’s coffee innovation brand. It translates the processor’s work into three focused expressions: Exotic & Rare NATCHA Lots available as green beans or roasted beans, Brew Archive freeze-dried coffee and private-allocation Divinum.
Its permanent philosophy is expressed in one line: Exotic by Fermentation - Rare by Nature.

Founder story · Natanael Charis
Natanael Charis did not begin with a perfect fermentation formula. An early batch went off course, leaving green beans that looked rough, uneven and easy to dismiss.
Roasting the coffee further made it bitter. When Natanael stopped a later test very early, just before first crack, the cup revealed what he described as a Lindt chocolate-orange character.
The result did not prove a process. It created a question worth pursuing. Since that discovery, he has committed himself to controlled fermentation, repeated trials and disciplined evaluation to develop coffees with distinctive cup profiles.
