Most kopitiam kopi in Malaysia is brewed from Liberica beans roasted dark with margarine and sugar. The style dates from an era when beans were cheap and customers wanted strength. Underneath that roast sits a coffee species the rest of the world barely grows. Malaysia never stopped growing it. It simply stopped noticing.
This is the story of the cup, the species underneath it, and what happens when the margarine is left out.
What kopi actually is
Kopi is a roasting style, not a species. The beans are roasted dark with margarine and sugar in the drum. The result is a black, glossy bean that brews thick and bittersweet through a cloth filter. Condensed milk finishes the job.
The beans underneath are usually Liberica, often with robusta alongside. Not by accident. Liberica is what Malaysia grows. The kopitiam trade has been buying local beans for a century, which makes kopi one of the few coffee traditions anywhere built on the rarest of the three commercial coffee species.
Order kopi at a Cheras kopitiam tomorrow morning and there is a fair chance you are drinking Liberica. You would never know. The roast sees to that.
How Malaysia ended up with Liberica
In 1869 a fungal disease called coffee leaf rust appeared in Ceylon. Within fifteen years it had destroyed most of the island's arabica. The disease moved across South India and down the Malay Peninsula, and by the 1890s Malaya's arabica plantations were finished.
Liberica was the answer. A different species, native to Liberia, it held up against the rust better than arabica, grew happily at low altitude and cropped heavily. For a brief period it was the dominant coffee species in Southeast Asia.
Then arabica recovered elsewhere, world prices moved on, and Liberica settled into the role it has held here ever since: the local bean, roasted dark, sold over marble tables. The longer version of that history is in the case for Liberica.
What the margarine hides
Roast Liberica clean, with nothing in the drum but the bean, and the species turns out to have a range the kopi roast never lets you hear.
The lot we roast today, Long Banga Honey from a single estate in Sarawak, cups with tangerine at the front, brown sugar and milk chocolate through the middle and coconut underneath. An earlier washed lot from Batu Kurau in Perak gave chocolate, dried fruit and a quiet suggestion of clove. Both carry more body than an arabica, and both take milk well, which should surprise nobody. Kopitiam drinkers worked that out generations ago.
Caffeine, for what it is worth, sits a little below arabica. The strength of kopi was always the roast and the dose, not the species. There is a longer sensory map in what Liberica coffee tastes like.
Two futures for the same bean
The kopitiam tradition needs no rescuing. It is one of the great coffee cultures, and the dark roast is part of its architecture.
But the species deserves a second reading. In 2025 a Kew-led study in Nature Plants used genomic data to separate Liberica and Excelsa into two species, and put the two together at probably under 1,000 tonnes, about 0.01 per cent of world coffee exports. How Liberica compares with arabica and robusta, in one table, is in Liberica vs arabica vs robusta. The trees that survived the rust are still in Malaysian soil, still cropping, at estates in Sarawak and Perak that never asked for the attention.
Malaysia spent a century treating its coffee as ordinary. It turns out to have been holding something rare.
A word on Cheras
We roast our Malaysian Liberica in Cheras, a few streets from kopitiams that have been serving the same species since before we existed. The showroom is open Monday to Friday, 11am to 3pm. Sarawak Long Banga Honey is usually on the brew bar, and tasting it against a memory of kopi is the fastest way to understand what this species has been quietly carrying.
The short answers
Is kopi made from Liberica coffee?
Usually, yes. Kopitiam kopi in Malaysia is typically brewed from Liberica beans, often blended with robusta, roasted dark with margarine and sugar. The roast style hides the species almost completely.
Why is kopi roasted with margarine and sugar?
The style dates from an era of cheap beans and hard-working customers. Margarine and sugar in the drum give a dark, glossy bean that brews thick, bittersweet and consistent through a cloth filter.
What does Malaysian Liberica taste like roasted clean?
Our Long Banga Honey gives tangerine, brown sugar and milk chocolate, with coconut underneath. An earlier washed Perak lot gave chocolate, dried fruit and a suggestion of clove. Both carry more body than arabica.
Where can I taste clean-roasted Liberica in Kuala Lumpur?
Our showroom in Cheras is open Monday to Friday, 11am to 3pm. Sarawak Long Banga Honey is usually on the brew bar.
