What Exactly Is Kopi?
In Singapore, kopi simply means “coffee” in Malay, but in practice, it refers to a very specific style of coffee commonly served at hawker centres, kopitiams (coffee shops), and food courts. Unlike Western-style coffee made with espresso or drip brewing, kopi uses robusta coffee beans that are roasted with sugar and sometimes butter or margarine. This roasting style gives kopi its signature dark, rich, and slightly caramelised flavour.
The ground coffee is then brewed using a cloth coffee sock — think of it like a giant reusable coffee filter — which produces a thick, strong coffee concentrate. This concentrate is then combined with different types of milk and sugar, depending on your order.
A Brief History of Kopi in Singapore
Kopi culture in Singapore has its roots in the 19th century, when Hainanese immigrants worked as cooks and café operators for British households. When they opened their own coffee shops, they adapted Western-style coffee to suit local tastes and budgets. Robusta beans were cheaper and stronger than Arabica, and roasting them with sugar and butter created a flavour profile that paired perfectly with condensed milk.
Over the years, kopitiams became community hubs — places where uncles read their morning papers, taxi drivers exchanged stories, and friends caught up over toast and eggs. Today, kopi remains a beloved part of Singapore’s daily rhythm.
The Kopi Lingo: How to Order Like a Local
Ordering kopi can feel like ordering a customised Starbucks drink, except instead of saying “venti oat milk caramel macchiato with one pump syrup,” you’ll be using short and snappy phrases in a mix of Hokkien, Malay, and English.
Here’s a breakdown of the most common orders:
- Kopi – Coffee with condensed milk (the default order).
- Kopi O – Black coffee with sugar (no milk).
- Kopi C – Coffee with evaporated milk and sugar (less sweet than condensed milk).
- Siew Dai – Less sugar.
- Kosong – No sugar.
- Peng – Iced version.
For example:
- “Kopi O kosong” = Black coffee, no sugar, no milk.
- “Kopi C siew dai peng” = Iced coffee with evaporated milk, less sugar.
Once you learn the lingo, you can mix and match to your taste — it’s a local coffee language all on its own.
The Types of Milk in Kopi
One of the main differences between kopi and Western coffee is the milk. Here’s what you might encounter:
- Condensed milk – Thick, sweet, and creamy; the most common choice.
- Evaporated milk – Creamy but unsweetened; used for “kopi C.”
- Fresh milk – Less common at hawker centres, but you might find it at modern kopi stalls.
These choices change not just the taste, but also the mouthfeel of your coffee. Condensed milk gives a dessert-like richness, while evaporated milk keeps things smoother and lighter.
Why Kopi Is Different from Western Coffee
There are a few key differences:
- Bean type – Robusta beans have a stronger, more bitter flavour and more caffeine than Arabica.
- Roasting style – Sugar and butter in the roasting process create a caramelised, slightly smoky flavour.
- Brewing method – The coffee sock brewing produces a smooth yet bold concentrate.
- Sweetness level – Kopi tends to be sweeter unless you specify otherwise.
As a barista, I like to say kopi is coffee’s working-class cousin — bold, straightforward, and no-nonsense, but with a personality you can’t forget.
How to Make Kopi at Home
If you’re craving kopi but don’t have a hawker centre nearby, you can try making it at home. Here’s a simplified method:
Ingredients:
- 15g ground robusta coffee (kopi roast if possible)
- 150ml hot water
- 30–40ml condensed milk (adjust to taste)
Method:
- Brew the coffee in a coffee sock or French press with hot water.
- Let it steep for about 3 minutes before straining.
- Stir in the condensed milk until fully combined.
- Serve hot or pour over ice for kopi peng.
Tip: For authenticity, use pre-mixed kopi powder from a Singapore brand like Killiney or Ya Kun.
The Modern Kopi Movement
While traditional kopitiams are still going strong, modern coffee shops have started giving kopi a makeover. You might find artisanal kopi brewed with higher-quality robusta or even robusta-Arabica blends, served in sleek cups with latte art.
Some cafés experiment with kopi cocktails, kopi ice cream, or even kopi in bread and desserts. It’s part of a growing effort to preserve kopi culture while introducing it to younger generations and tourists.
Pairing Kopi with Food
If you want the full kopi experience, pair your cup with classic local breakfast dishes:
- Kaya toast – Crispy bread with coconut jam and butter.
- Soft-boiled eggs – Drizzled with soy sauce and pepper.
- Curry puffs or buns – Perfect for an afternoon kopi break.
The sweetness and strength of kopi balance beautifully with the savoury and buttery flavours of these snacks.
Where to Get the Best Kopi in Singapore
You’ll find kopi almost everywhere in Singapore, but here are a few spots worth trying:
- Ya Kun Kaya Toast – A heritage brand serving kopi since 1944.
- Killiney Kopitiam – Famous for its smooth kopi and kaya toast.
- Tong Ah Eating House – A traditional kopitiam with old-school charm.
- Heap Seng Leong – Known for kopi and kaya toast served with a side of nostalgia.
Each of these spots has its own unique roast and brewing style, so try a few and find your favourite.
Why Kopi Is Here to Stay
In a city that’s constantly changing, kopi remains a cultural anchor. It’s not just about the drink — it’s about the ritual, the lingo, the community, and the comfort of knowing you can get a satisfying cup for under $2.
Whether you’re a first-timer learning the difference between kopi C and kopi O, or a long-time fan who has your order down to a science, kopi is part of Singapore’s heart and soul. And once you’ve learned how to order it, you’ll always feel a little more at home here.
Final Sip: Next time you’re in Singapore, skip the fancy latte and try ordering a kopi like a local. Not only will you get a bold, flavourful cup of coffee, but you’ll also be taking part in a tradition that has been brewing for over a century.
Frequently Asked Questions (FAQ)
1. Is kopi always made with Robusta beans?
Not always. Traditional kopi in Singapore tends to use Robusta or Robusta-heavy blends because of its stronger flavour and cost effectiveness. But as kopi evolves, many roasters and cafés are experimenting with higher-quality Arabica or blends of Arabica + Robusta to bring in more floral or fruity notes. So you’ll see both, depending on where you’re ordering.
2. What does “sock filter” mean and why is it used?
The sock filter (also called a cloth sock or kopi sock) is a cloth mesh filter that brews coffee by letting hot water drip through the grounds. It’s traditional in kopi stalls. It retains more oils than paper filters, giving kopi that signature full body, richness, and caramelised flavor. It’s been used for decades because it balances strength and flavour very well.
3. What’s the difference between kopi O, kopi C, kopi peng, and kosong?
These terms are part of the kopi lingo:
- Kopi O = black coffee with sugar (no milk).
- Kopi C = coffee with evaporated milk and sugar.
- Peng means iced — so “kopi peng” = iced kopi.
- Kosong means no sugar.
You can mix these terms. Example: “kopi O kosong” = black coffee, no sugar; “kopi C siew dai peng” = iced coffee, with evaporated milk, less sugar.
4. How do the different milks affect the taste of kopi?
Condensed milk gives kopi a thick, sweet, almost dessert-like richness. Evaporated milk adds creaminess without extra sugar, giving a smoother, more balanced cup. Fresh milk is less common in traditional kopi stalls but is used in newer kopi-style cafés. It lightens the body a bit and can reveal more of the roast and bean character.
5. Can I replicate kopi at home, even without kopi stalls? What do I need?
Yes, you absolutely can! Here’s what helps:
- A cloth sock filter or something similar.
- Robusta coffee beans (or a blend), ideally roasted dark or kopi-style.
- Hot water, just off the boil.
- Condensed or evaporated milk (depending on your preference).
Follow the method in the guide: steep the coffee, strain, mix with milk, or pour over ice for kopi peng. While you might not get the exact taste of a kopi uncle’s brew, you’ll get pretty close.
6. How do modern kopi cafés differ from traditional kopitiams?
Modern kopi cafés often do a few things differently: they might use higher-grade beans, offer Arabica blends or single origins, present kopi in stylish ceramic or glassware, offer cold brew or kopi-infused desserts, and adjust sweetness more broadly. But many still pay homage to tradition by using kopi lingo, thick roasts, or even the sock filter. The difference is often in presentation, ambience, and the detail of flavour.
7. Why is kopi so central to Singapore’s culture?
Kopi isn’t just a drink — it’s a ritual, a daily comfort, and a piece of heritage. It has roots in the immigrant history (especially Hainanese cooks and kopitiam culture), it’s affordable, and it brings community together: people meeting at kopitiams, sharing kaya toast and soft-boiled eggs, starting their day together. Even as coffee trends change, kopi remains beloved because it symbolises daily life, warmth, and familiarity.
