Kopi Kothok Recipe: Boiled Coffee, Ratio and Tubruk Comparison
Kopi kothok is coffee brewed by heating ground coffee and water together in a pot. Let the grounds settle, pour slowly and add sugar to the cup so you can adjust sweetness independently of what stays in the pan.

Key Takeaways
- 1Choose kopi kothok for a stovetop brew with a substantial texture; choose tubruk for the simpler cup-brewed approach.
- 2A gentle simmer and a settled pour keep the coffee satisfying without making the last sip gritty.
- 3Aim for the measured coffee portion, but stop before thick sediment follows and accept a smaller pour.

How to Make Kopi Kothok
The defining step is heating the grounds with the water. The Bojonegoro study and Yogyakarta tourism account describe that pot-brewing method. Here, sugar goes into the poured cup so you can measure it independently of liquid left in the pan.
Recipe
Kopi Kothok
- Makes:
- 1 small coffee; aim for 150 g brewed coffee before sugar
- Time:
- About 10 minutes, including 2 minutes resting
Ingredients
- 12 g medium-fine ground coffee
- 200 ml (6.8 US fl oz) water
- 5 g (1¼ US tsp) white granulated sugar
Equipment
- Small saucepan with generous headroom
- Scale
- Liquid measure
- Timer
- Spoon
- Hob or compatible heat source
- Heatproof cup, at least 200 ml (6.8 US fl oz)
Method
- Combine 12 g medium-fine ground coffee and 200 ml (6.8 US fl oz) water in a small saucepan with generous headroom.
- Warm over medium-low heat, stirring briefly. At a gentle simmer, reduce the heat and simmer for 1 minute; watch continuously and lift it off the heat if the coffee rises toward the rim.
- Remove from the heat. Rest undisturbed for 2 minutes so the grounds settle.
- Tare a heatproof cup on a scale. Pour slowly toward a 150 g (5.3 oz) coffee portion, stopping before thick sediment follows. Accept a smaller pour if needed; do not top up.
- Dissolve 5 g (1¼ US tsp) white sugar in the poured coffee. Let it cool enough to sip, and leave any gritty remainder.
Estimated nutrition: 21 kcal · 5 g total sugar. Per serving, including 5 g sugar.

Use a normal kitchen heat source and a pan you can lift and pour safely. You do not need charcoal, dry-frying or a vigorous rolling boil. Keep the handle away from the hob edge and the pan in view: coffee can rise abruptly as it heats.
Kopi Kothok vs. Kopi Tubruk

| Drink | Where brewing happens | What happens to the grounds |
|---|---|---|
| Kopi kothok, as described here | Coffee and water heat together in a pot | Rest the pot, then pour carefully |
| Kopi tubruk | Hot water meets grounds in the drinking cup | They remain in the cup while you sip |
| Turkish coffee | Very finely ground coffee is heated in a small pot | Served unfiltered, with its own recipe and service conventions |
| Kopi joss | Preparation and service vary | The charcoal addition distinguishes the served drink |
Kothok, Klothok and Klotok
Kopi kothok has a documented place in Bojonegoro, East Java. A 2019 design study by Kristian Oentoro drew on the area’s coffee-drinking tradition to develop a local pottery coffee set. The name also resembles klothok or klotok in Yogyakarta: the regional tourism office describes coffee and water cooked together at Warung Kopi Klothok in Kaliurang, Sleman.
Those names can lead you to related pot-brewed coffees, but they also refer to particular local traditions and businesses. If you are looking for the well-known Kaliurang venue, include its location in your search; Bojonegoro’s kopi kothok is a separate regional reference.
Kopi Kothok Ratio and Serving Size
The starting input is 12 g coffee to 200 ml (6.8 US fl oz) water, 1:16.7 if the water weighs 200 g. Some water evaporates; wet grounds and coffee stay in the pan. The recipe therefore separates the following measurements:
| Measurement | Meaning in this recipe |
|---|---|
| 12 g dry coffee | What goes into the saucepan |
| 200 ml (6.8 US fl oz) water | Input before heating; not a 200 ml (6.8 US fl oz) finished drink |
| 150 g (5.3 oz) poured coffee | A target portion weighed after brewing |
| 5 g (1¼ US tsp) sugar | Added to that cup, so it is separate from pan losses |
If you recover less than 150 g (5.3 oz) before thick sediment follows, keep the smaller serving. Do not force the remaining sludge through or quietly count a water top-up as recovered coffee. You can instead add less sugar to suit that smaller cup. For two intended portions, heat 24 g coffee with 400 ml (13.5 US fl oz) water in a larger pan, simmer gently for 1 minute and rest for 2 minutes. Aim to pour 150 g (5.3 oz) coffee into each cup, stopping before thick sediment follows, then add 5 g (1¼ US tsp) white sugar to each. Accept smaller pours without topping up.
Flavor and Tasting Notes
Kopi kothok has the substantial feel of coffee brewed with its grounds in the pot. With a dark roast, expect a firm bitter edge and lingering toasted flavors; the small sugar addition softens that edge without adding milk. Resting and pouring carefully leaves the heaviest sediment behind, although the cup will still feel less clean-cut than paper-filtered coffee.
I would use a medium-dark roast with a cocoa-like finish because it gives this simmered coffee depth without relying on an aggressively smoky roast.
For milk-based variations, explore kopi susu or coconut-milk kopi santan.
Kopi Kothok Caffeine, Calories and Sugar
A 150 g (5.3 oz) coffee portion with 5 g (1¼ US tsp) white sugar has an estimated 21 kcal and 5 g total sugar, using generic brewed coffee as the proxy. Caffeine has not been measured for this pot. The table holds the coffee portion constant:

| White sugar in the cup | Modeled calories, including coffee | Modeled total sugar |
|---|---|---|
| 0 g | 2 kcal | 0 g |
| 5 g (1¼ US tsp), recipe amount | 21 kcal | 5 g |
| 10 g (2½ US tsp) | 40 kcal | 10 g |
Coffee-proxy and sugar calculation
USDA brewed coffee record 171890 supplies 1 kcal and 0 g total sugar per 100 g; granulated sugar record 169655 supplies 387 kcal and 99.8 g sugar per 100 g. The unrounded middle row is 1.5 + 19.35 = 20.85 kcal, with 4.99 g sugar. These comparisons hold the coffee portion constant and change only the sweetener. The estimates cover the complete modeled serving.
Fixing Bitter or Gritty Kopi Kothok
| Mistake or symptom | Better fix |
|---|---|
| Coffee rises toward the rim | Lift off the heat; use more pan headroom and less heat next time |
| Too gritty | Rest without stirring, pour slowly and stop earlier |
| Bitter or drying | Try a gentler or shorter simmer, then adjust roast or grind separately |
| Too weak | Raise the coffee dose slightly next time while keeping water input fixed |
| Too sweet | Reduce the weighed sugar in the served cup |
A fine strainer may catch larger particles, while paper filtration changes the texture more substantially. Neither is required for this home version.
