Step inside Singapore's first certified traditional coffee roastery. Watch the drums turn, smell the caramel, learn to pull your own kopi through a cloth sock — and taste the cup that has powered Singapore's kopitiams for over 35 years.
Kim Guan Guan Coffee has been quietly powering Singapore's kopi culture since 1988. Founded by Jason Soon, the roastery supplies over 1,600 kopitiam stalls across the island — meaning most Singaporeans have drunk their coffee without ever knowing it. Today it holds the distinction of being Singapore's first FSSC 22000-certified traditional coffee roastery, the food-safety gold standard usually associated with large-scale manufacturers.
This is not a museum. It is a working roastery operating the same way it has for decades — with large drum roasters, Robusta and Liberica beans imported from Indonesia, and skilled workers breaking apart caramelised bean cakes by hand before they cool and harden. A visit here is one of the few remaining places in Singapore where you can witness this vanishing craft up close.
A full sensory journey through Singapore's most beloved daily ritual.
The centrepiece of any visit is the large roasting drum — a rotating vessel where green coffee beans are tumbled together with maize, margarine and sugar over high heat. As the caramelisation takes hold, the factory fills with a thick, sweet aroma unlike any coffee shop. The dramatic moment comes when the roasted beans drop down a chute into a large cooling pan, releasing great clouds of steam and smoke. Workers then move fast — the caramelised cakes must be broken apart by hand before they cool and fuse solid.
Nanyang kopi is not brewed with a machine. Ground coffee is steeped inside a narrow cloth sock — a small fabric infuser — inside a tall metal kettle. The filter is raised and lowered repeatedly with a practised rhythm, and the result depends entirely on experience: how long, how many passes, how hot the water. This hand-pulled technique produces a full-bodied, silky cup that no espresso machine can replicate. Participants have the chance to try brewing themselves under guidance.
Singapore's coffee culture comes with its own ordering language. Participants taste different preparations side by side and learn to decode the lingo:
Side snacks like kaya roti (bread with kaya) complete the authentic kopitiam experience — pairing it with a strong kopi is a ritual as old as the drink itself.
A guided segment covers the history and culture behind every cup: how Hainanese immigrants brought the kopitiam model to Singapore, why Robusta beans became the local standard, how the ordering system evolved, and why this tradition is worth preserving. For school groups, this connects directly to Singapore Studies, Social Studies and character education themes around heritage and identity. Participants leave with a genuine appreciation for something they walk past every day.
An ideal field trip for upper primary and secondary students studying Singapore heritage, Social Studies or CCE. The roastery setting is memorable, the learning is concrete and the kopi tasting gives everyone a story to bring home. We handle logistics; you show up with your group.
A rare chance for parents to show children something genuinely old Singapore — not a replica or a museum diorama, but the real machines and real workers who supply the coffee your grandfather drinks every morning. Works beautifully as part of a Geylang Serai or Joo Chiat heritage trail.
Swap the generic team lunch for something your colleagues will actually remember. The roastery tour pairs well with a kopi brewing competition, custom-labelled bags as takeaways, or a discussion on Singapore identity and local business heritage. Groups of 20 to 80 welcome.
For many seniors, the smell of roasting kopi is a living memory. This tour connects them to the Singapore of their youth in a way few experiences can. RC, CC and active-ageing groups regularly find this the most personally meaningful outing we offer.
Kim Guan Guan Coffee was founded in 1988 by Jason Soon with one goal: to supply quality traditional coffee powder to Singapore's food and beverage outlets. More than 35 years later, the company has grown into a fully integrated operation handling imports, roasting, grinding, packaging and distribution — while keeping the same core process unchanged.
They are Singapore's first FSSC 22000-certified traditional coffee roastery, a certification that requires rigorous food safety management typically found only in large-scale manufacturing. Their beans supply over 1,600 kopitiam stalls across Singapore, and their products are now exported internationally, carrying Singapore's kopi heritage to Australia and beyond.
Jason Soon continues to lead the business and champion Singapore coffee culture, actively introducing the craft to new audiences. The Kim's Duet product line — launched in 2021 as "Tradition in a Bag" — brings the same quality to consumers who want the authentic taste without the wok and sock.
