Kopi Susu: Hot Condensed-Milk and Iced Gula Aren Recipes

Which Kopi Susu Do You Mean?

Kopi susu means coffee with milk, rather than one fixed recipe. This page focuses on Indonesian versions: a simple hot coffee with sweetened condensed milk and a separate modern iced coffee with fresh milk and gula aren syrup.

I ask which kopi susu is being made before ordering. The hot condensed-milk version gives me a compact, rich sweetness; the iced fresh-milk version with gula aren gives me a longer drink with palm sugar as a separate flavor.

Choose between these two recipes; the hot condensed-milk version can also be cooled and iced. Some cafés combine condensed milk, fresh milk, creamer and syrup. Es indicates an iced version; gula aren names the palm-sugar ingredient.

Flavor and Tasting Notes

The hot condensed-milk recipe tastes sweet and creamy, with a cooked-milk note wrapped around the coffee’s roast. It has more weight than coffee with an ordinary splash of milk, and the finish is a mix of lingering dairy sweetness and coffee bitterness.

The iced gula aren version has a lighter milk texture and a darker, caramel-like sweetness from the syrup. Some palm sugars bring a smoky edge, making the sweetener part of the flavor rather than just a way to soften coffee.

For the hot version, I would choose a nutty medium-dark coffee because condensed milk brings out its praline-like side without needing another flavoring.

Kopi Susu Recipes

Hot Kopi Susu with Condensed Milk

This small hot version needs just prepared coffee and sweetened condensed milk.

A French press or pour-over works. Prepare a little more coffee than needed, then weigh the 120 g (4.2 oz) portion; do not assume water poured into a brewer all reaches the cup.

Plain instant coffee is another option when prepared according to its label, then weighed as finished coffee. A 3-in-1 packet already containing sugar or creamer is a different ingredient. Espresso makes another, more concentrated version; it is not a drop-in 120 g (4.2 oz) replacement for brewed coffee.

Hot, Iced and Gula Aren Kopi Susu

Iced Condensed-Milk Version

Stir 20 g (1 US tbsp) condensed milk into 120 g (4.2 oz) hot prepared brewed coffee until smooth and let it cool. Pour over 100 g (3.5 oz) ice in a 300 ml (10.1 US fl oz) glass and stir again. Meltwater dilutes the drink.

Fresh-Milk Gula Aren Version

For one separate home starting point, use:

• 36 g prepared espresso, brewed with the espresso guide and allowed to cool
• 100 ml (3.4 US fl oz) cold milk
• 10 ml (2 US tsp) gula aren palm-sugar syrup
• 100 g (3.5 oz) ice

Combine the syrup and milk in a 300 ml (10.1 US fl oz) glass, add ice and the cooled espresso, then stir. Use syrup already dissolved to avoid gritty sugar in a cold drink. NESCAFÉ Indonesia's gula aren guidance likewise distinguishes dry sugar from syrup and discusses fresh milk and optional creamer.

Syrup concentration matters. Ten milliliters of a thin homemade syrup is not automatically as sweet as 10 ml (2 US tsp) of a concentrated commercial one. Gula aren is not simply a promise of low sugar; use the actual syrup label when calculating nutrition. If buying a different palm or coconut sugar, check the ingredient identity instead of assuming it is the same product.

Regional and Modern Kopi Susu

Coffee with milk takes several forms in Indonesia. Sanger has its own Acehnese identity and frothy serving tradition. Kopi Kenangan’s 2022 Black Aren launch announcement offers another example: coffee, fresh milk and aren sugar, with a smoky aroma from its chosen sugar. These examples explain why asking about the milk and sweetener tells you more than “kopi susu” alone.

Kopi Susu Caffeine, Calories and Sugar

The hot recipe has an estimated 65 kcal and 11 g total sugar, with a 50 mg generic caffeine reference. These figures apply to the stated 120 g (4.2 oz) prepared coffee plus 20 g (1 US tbsp) condensed milk, without additional sugar or toppings.

The fresh-milk iced variation uses 36 g prepared espresso, with a separate ~75 mg generic reference from USDA espresso record 171891. That difference comes from the selected coffee portions and references, not an inherent hot-versus-iced rule. Its calories and sugars need the chosen 100 ml (3.4 US fl oz) milk and 10 ml (2 US tsp) syrup labels; the hot recipe's 65 kcal does not apply.

Adjusting Sweetness and Coffee Strength

At the same 120 g (4.2 oz) coffee portion, changing condensed milk gives this transparent label comparison:

The table uses the same Carnation label and generic coffee reference. It includes naturally occurring milk sugar and added sugar; the label does not provide their separate amounts. Less condensed milk changes dairy richness as well as sweetness, while the measured coffee portion stays the same.

Evaporated milk is unsweetened concentrated milk, so it is not an equal-sweetness substitute. Fresh milk adds more dilution for a given mass. For a plant-based version, choose a suitable condensed alternative or use fresh plant drink and a separate sweetener; recalculate from its label, matching grams to gram-based labels and milliliters to volume-based labels.

Adjusting Your Kopi Susu

Kopi Susu vs. Latte or Vietnamese Iced Coffee

A plain latte uses espresso and steamed milk without requiring a sweetener. Kopi susu has a broader set of coffee bases and sweetening choices. Vietnamese iced coffee commonly brings together phin-brewed coffee, condensed milk and ice; the shared ingredients do not make the regional names identical, and this hot kopi susu recipe needs no phin.

For coconut milk rather than dairy, see kopi santan. For the separate Malaysian roast tradition, see Ipoh white coffee.
