It’s made with arak (a potent spirit), strong coffee, and creamy milk. This drink is not just a sip; it’s an experience. In this guide, I’ll break down what arak kopi susu is, its cultural background, and give you a simple recipe to make it at home.
Trust me, this is one spiked coffee that will impress your friends.
What Exactly Goes Into an Arak Kopi Susu?
Arak is a distilled spirit, often made from sugarcane or coconut flower sap. Think of it as a rustic white rum or cachaça. It’s got a strong, unique flavor.
Kopi refers to the coffee used in this drink. You want a strong, bold flavor, typically from a dark roast. An Indonesian single-origin coffee works perfectly.
Susu means milk, and in this case, sweetened condensed milk is the classic choice. It adds a rich texture and sweetness that balances the strong spirit and coffee.
The arak kopi susu is a popular local concoction in places like Bali, Indonesia. It’s often enjoyed as a potent and energizing social drink.
The combination creates a unique flavor profile that is simultaneously sweet, creamy, and intensely strong. It sets it apart from other coffee liqueurs or cocktails.
Pro tip: If you can’t find arak, a good substitute is a robust white rum or cachaça. Just make sure it has a similar strength and character.
Gathering Your Ingredients and Tools
Let’s get to the nitty-gritty. Here’s what you need for a perfect arak kopi susu:
- Arak: If you can’t find authentic Balinese arak, go for unaged Jamaican rum or cachaça. They both have a similar kick.
- Coffee: Use freshly brewed espresso (chilled) or a high-quality, strong cold brew concentrate. You want that robust, non-watery flavor.
- Sweetened Condensed Milk: Canned sweetened condensed milk is the way to go for authenticity. But if you have dietary restrictions, try coconut cream with maple syrup or oat milk with simple syrup.
Now, let’s talk tools:
- Cocktail Shaker: Essential for mixing and chilling your drink.
- Jigger or Measuring Spoons: Get those measurements right.
- Strainer: For a smooth, sediment-free pour.
- Rocks Glass or Coupe: Choose based on your serving style.
Pro tip: Don’t forget plenty of good quality ice, both for shaking and for serving. It’s crucial for the right temperature and dilution.
How to Make the Perfect Arak Coffee Milk: A Step-by-Step Guide

Start with precise measurements for a balanced drink, for example: 2 oz Arak (or substitute), 2 oz strong chilled coffee, and 1 oz sweetened condensed milk. Adjust the sweetness to your personal taste.
Step 1: Chill Your Glass
Fill your serving glass with fresh ice to chill it while you mix. This step is often overlooked but makes a big difference in the final drink. Fpmomhacks
Step 2: Combine Ingredients
Combine the arak, chilled coffee, and sweetened condensed milk in your cocktail shaker. The sweetened condensed milk adds a rich, creamy texture that complements the strong flavors of the arak and coffee.
Step 3: Shake It Up
Fill the shaker about two-thirds full with ice, seal it tightly, and shake vigorously for 15-20 seconds. Shaking is key to chilling, diluting, and creating that smooth, creamy texture.
Step 4: Strain and Serve
Strain the mixture from the shaker into your prepared, ice-filled glass. This step ensures that no ice chips make their way into your drink, keeping it smooth and refreshing.
For an optional but elegant garnish, add three coffee beans on top or a light dusting of cinnamon or cocoa powder. This enhances the aroma and adds a touch of sophistication.
And there you have it, a perfect arak kopi susu. Enjoy!
Flavor Profile, Variations, and Serving Suggestions
Let’s talk about the taste. The arak kopi susu has a velvety, rich mouthfeel with a bold coffee punch. It’s followed by the sweet, slightly funky notes of the arak, and a long, creamy finish.

Or, try using spiced rum for a different flavor profile.

There is a specific skill involved in explaining something clearly — one that is completely separate from actually knowing the subject. Wilburn Cliftere has both. They has spent years working with expert parenting advice in a hands-on capacity, and an equal amount of time figuring out how to translate that experience into writing that people with different backgrounds can actually absorb and use.
Wilburn tends to approach complex subjects — Expert Parenting Advice, Family Activities and Projects, Parenting Tips and Hacks being good examples — by starting with what the reader already knows, then building outward from there rather than dropping them in the deep end. It sounds like a small thing. In practice it makes a significant difference in whether someone finishes the article or abandons it halfway through. They is also good at knowing when to stop — a surprisingly underrated skill. Some writers bury useful information under so many caveats and qualifications that the point disappears. Wilburn knows where the point is and gets there without too many detours.
The practical effect of all this is that people who read Wilburn's work tend to come away actually capable of doing something with it. Not just vaguely informed — actually capable. For a writer working in expert parenting advice, that is probably the best possible outcome, and it's the standard Wilburn holds they's own work to.
