In-House Roasting Won't Save Your Café — But Here's What It Actually Does

Green coffee prices cracked US$4 per pound in early 2025, a record high that sent roasters and café owners scrambling for options (via Perfect Daily Grind). One idea that keeps resurfacing: roast your own beans, cut out the middleman, control your margins. It sounds logical. It’s also more complicated than a quick back-of-napkin calculation makes it look.

Perfect Daily Grind ran the numbers, and the conclusion is sobering: raw green coffee costs are actually a relatively small slice of a café’s total expenditure. Rent in Bangsar or Damansara Uptown, wages for your baristas, packaging, oat milk that costs twice what full-cream does — these are the line items quietly eating your margins. Bringing a roaster in-house shifts one variable. It doesn’t solve the equation.

That said, the calculus looks different depending on what kind of operation you’re running.

For a high-volume standalone roastery — the kind supplying beans to five or six café accounts around KL — in-house roasting makes obvious sense. You’re already at the scale where the equipment pays for itself, and you’ve probably got someone on staff who can actually dial in a roast profile without guessing. Think of the operations feeding the Publika or Desa Park City café clusters. They’re not debating this anymore.

The trickier question is for the single-outlet specialty café — the kind that’s doing maybe 15 to 20 kg of coffee a week. A decent entry-level drum roaster, even a secondhand Probat or a Taiwanese machine sourced through a regional distributor, will run you anywhere from RM30,000 to well over RM100,000 once you factor in installation, ventilation compliance, and the time investment for whoever’s learning to roast consistently. That’s before you’ve bought a single bag of green beans.

And green bean sourcing in Malaysia isn’t trivial. You’re looking at a handful of established importers bringing in lots from Ethiopia, Colombia, Yemen, and increasingly from our own backyard — Sabah liberica, Kelantan robusta, the occasional experimental Peninsular arabica plot. Minimum order quantities and inconsistent supply mean smaller cafés often can’t access the same lots the big roasters are buying. You end up with a roaster sitting half-idle because you couldn’t fill a full order.

There’s also the quality ceiling issue. Roasting is a skill. Dialling in a Kenyan AA for filter is a different muscle from coaxing a natural Ethiopian into an espresso blend. Malaysian baristas have gotten exceptionally good at the extraction side — our competition scene proves that. But roasting talent is a separate discipline, and training it properly takes months, not weekends.

Where in-house roasting genuinely delivers value — and this is the part the Perfect Daily Grind piece gets right — is in brand differentiation and menu control. If you’re Zus or a chain with 200 outlets, you’re already centralising your roasting because the economics demand it. But if you’re a ten-table café in Subang Jaya trying to stand out from the three other specialty spots on the same street, being able to say “we roast here, on that machine by the window, every Tuesday” is legitimately compelling. Customers care. It creates regulars.

The honest answer for most Malaysian café owners right now: don’t roast to save money, because you probably won’t. Roast because you want creative control, you’ve got the volume to justify the equipment, and you have someone on your team who’s genuinely obsessed with it. Otherwise, build a strong relationship with a local roaster you trust — there are excellent ones in KL, Penang, and JB — and put your energy into extraction, hospitality, and not charging RM18 for a piccolo.

The coffee is expensive enough already.
