From a Rp10,000 street cart to Google Doodle. Explore the history, unique flavors, and economic impact of Indonesia’s beloved kopi susu gula aren.
A Drink That Became a Cultural Movement
Indonesia’s coffee scene has gone through many waves. But if there is one product that has fundamentally reshaped how millions of Indonesians consume coffee on a daily basis, it is Es Kopi Susu Gula Aren, iced palm sugar milk coffee.
This drink has transcended social class, age, and personal taste. It is just as satisfying to be sipped from a Rp10,000 plastic cup at a street cart as it is from a ceramic mug in a premium, Instagram-worthy café.
And now, the world is starting to take notice. On July 15, 2025, Google celebrated kopsuren as it is affectionately nicknamed, as its daily Google Doodle. A global acknowledgment of a drink born from the marriage of local coffee, fresh milk, and a traditional sweetener that Indonesian ancestors have used for centuries.
So how exactly did this humble drink become the soul of Indonesia’s modern coffee culture?
From Cendol to Coffee Cup: An Unexpected Origin Story
Milk coffee in Indonesia has deep roots. The habit of drinking coffee with milk was first introduced by Europeans during the Dutch colonial era, though at the time it was a luxury reserved for the privileged few, fresh milk being a costly commodity.
After independence, Indonesians began adapting the recipe to suit local realities. Fresh milk was replaced with sweetened condensed milk. Cheaper, longer-lasting, and far more agreeable to the local palate. From this adaptation came the warm kopi susu tubruk, the staple of traditional coffee shops across the archipelago and the earliest ancestor of the iced milk coffee we know today.
A new chapter opened in 2015, when Kopi Tuku was founded in Jakarta. Its founder, Andanu Prasetyo, began experimenting with palm sugar, a traditional Indonesian ingredient familiar from drinks like cendol, and combined it with coffee and milk, creating a drink that went viral almost immediately.
By 2017 and 2018, the trend had fully exploded. Small kopsuren stalls began sprouting across the country, and many of those humble booths have since grown into large chains with hundreds of branches nationwide.
Why Palm Sugar?
To truly understand what makes kopsuren so special, we need to get better acquainted with its real star ingredient: palm sugar.
Palm sugar, known locally as gula aren, is extracted from the sap of the sugar palm tree, which is then cooked down until it thickens. The process yields a naturally sweet flavor with a caramel aroma and a subtle smoky finish that pairs exceptionally well with the robusta beans widely used in Indonesian coffee. It is a depth of flavor that synthetic sweeteners simply cannot replicate. Some also describe it as having hints of caramel and butter, a warmth that feels almost nostalgic.
Unlike coconut palm sugar, gula aren carries a bolder aroma and a relatively lower glycemic index. It also contains polyphenols and flavonoids. Compounds well-regarded for their health benefits. The fact that a traditional local ingredient can now hold its own against the standards of international cafés is, in itself, a quiet kind of triumph.
The Anatomy of a Perfect Glass
Creating a glass of kopsuren that is genuinely delicious. The kind that keeps customers coming back follows a formula that seasoned baristas tend to agree on.
The foundation is espresso, typically a blend of arabica and robusta beans chosen for a bold character that does not get lost beneath the milk. Over that goes fresh milk or UHT, which adds a smooth, savory softness. Then comes the soul of the whole drink: thick, genuine palm sugar syrup, never artificial flavoring. Some baristas finish it off with a splash of creamer for a velvety texture and extra richness on the palate.
One widely used tip: cook the palm sugar syrup together with pandan leaves. The result is a noticeably more complex, fragrant aroma, a small detail that makes an outsized difference in every sip.
A Local Business Revolution
Indonesia’s café market is projected to reach USD 2.1 billion (approximately Rp34 trillion), growing at an annual rate of around 10%, and the kopsuren trend has been one of the key engines powering that growth. This single menu innovation has genuinely reshaped Indonesia’s daily coffee-drinking culture.
The success of palm sugar coffee is closely tied to a smart business model: low-cost, compact booths combined with seamless integration into food delivery apps like GoFood and GrabFood. Local brands such as Kopi Kenangan, Fore Coffee, Tuku, and Point Coffee compete fiercely. Not just among themselves, but against global giants like Starbucks and Coffee Bean.
A glass of kopsuren typically costs between Rp10,000 and Rp25,000, making it significantly more accessible than a cappuccino at a sit-down café. That affordability is precisely what allows Kopsuren to reach everyone. From students stretching a tight budget to professionals who want quality coffee without spending a fortune.
Economic Impact: Giving Life to Local Palm Sugar Farmers
Behind every drop of that rich brown syrup, an entire economy quietly stirs.
The sharp surge in demand for palm sugar has spurred the growth of aren palm plantations in regions like West Java, Banten, and Sulawesi. Beyond the farmers themselves, this boom has also breathed new life into small and medium enterprises that process raw palm sugar into ready-to-use liquid syrup for cafés. A product that barely existed as a commercial category just a decade ago.
According to domestic trade data, palm sugar consumption for the coffee industry has grown by more than 300% over the past five years. It is a concrete example of how a single beverage trend can ripple outward and directly improve livelihoods in the agricultural sector.
MURI Records to Google Doodle: A Recognition Well Earned
Kopsuren has not just won over taste buds; it has made history.
It began in Semarang Regency in October 2022, when 13,609 participants simultaneously drank palm sugar coffee, setting a new Indonesian Record (MURI). That record was then shattered in July 2024 in South Sumatra, where an astonishing 27,000 residents drank coffee together at the same moment.
The pinnacle of global recognition arrived on July 15, 2025, when Google immortalized the drink as a Google Doodle themed “Celebrating Kopi Susu Gula Aren.” The Doodle was released to mark the first anniversary of the South Sumatra MURI record, while also celebrating the broader ecosystem of modern coffee shops and mobile coffee vendors, the beloved starling cyclists who pedal their thermos-laden bikes through neighborhood streets.
What began as an experiment in a Rp10,000 plastic cup on a Jakarta sidewalk has since expanded internationally, gaining recognition in Singapore and Malaysia as a genuine representation of Nusantara flavors on the world stage.
How to Make Café-Style Iced Palm Sugar Coffee at Home
You do not need an expensive espresso machine to enjoy this drink. Here is a straightforward recipe using everyday kitchen methods:
Ingredients:
- 2 tablespoons of finely ground coffee, no sediment (recommended: a robusta-arabica blend)
- 100 ml hot water
- 30–50 ml genuine palm sugar syrup
- 120 ml full-cream liquid milk
- Creamer to taste (optional)
- Ice cubes
Instructions: Brew the coffee using hot water, a traditional tubruk method, or a Vietnamese drip filter both work well. Place the palm sugar syrup at the bottom of a serving glass. Fill the glass about three-quarters full with ice cubes. Slowly pour in the creamer and milk. Finally, pour the black coffee gently over the top. Stir well before drinking so the palm sugar blends fully with the milk and coffee.
Will Kopsuren Last? The Case for Yes
In a world where globalization routinely displaces local products, kopsuren has moved in the opposite direction entirely. It proves that traditional ingredients, when packaged intelligently and presented with intention, can compete and even dominate in a market saturated with outside influences.
Many food trend observers have asked the inevitable question: Is this just a fad?
The answer lies like the ingredient itself. Palm sugar did not become popular because of a viral moment. It has been woven into the DNA of Nusantara cuisine long before the first modern café opened its doors. Kopsuren simply gave it a new, more visible stage. Future innovations will likely see it paired with plant-based milks like oat or almond milk as health-conscious consumers grow in number. But palm sugar itself will almost certainly remain the irreplaceable flavor anchor.
Much like sweet tea has never truly left the Indonesian dining table, kopi susu gula aren has found its permanent place. Not as a trend, but as a new flavor standard that the country has already fallen in love with.
