What to check first

Brewer type and filter type

This recipe works with most strong brewing methods. Think French press, pour-over, or even a robust drip machine. For a traditional Thai coffee vibe, a fine mesh strainer or a cloth filter is classic. If you’re using a paper filter, make sure it’s rinsed to avoid any papery taste messing with your sweet brew.

This recipe works with most strong brewing methods, including a French press. If you’re a fan of this method, you’ll find it works wonderfully here.

Water quality and temperature

Good water makes good coffee. Use filtered water if your tap water has a funky taste. For brewing, you want it hot, but not boiling. Aim for around 195-205°F. Too cool and you won’t extract enough flavor. Too hot and you can scorch the grounds.

Grind size and coffee freshness

This is key. For Thai coffee, you want a fine grind, almost like espresso or even a touch finer. This helps get that rich, intense flavor we’re after. Freshly ground beans are always best. If your coffee’s been sitting around for months, it’s not going to taste as vibrant.

For this recipe, a fine grind is crucial for that rich, intense flavor. If you don’t have one, a quality coffee grinder fine can make all the difference.

Coffee-to-water ratio

You want this coffee strong. Think about a 1:15 or 1:16 ratio as a starting point for brewing, but lean towards more coffee. For example, use 2 tablespoons of coffee for every 6 oz of water. You can always add more milk and sugar, but you can’t un-dilute weak coffee.

Cleanliness/descale status

Nobody likes a bitter coffee that tastes like old grounds. Make sure your brewer and any accessories are clean. If you’ve got mineral buildup in your machine, it’s time to descale. A clean setup means a clean, pure flavor.

Step-by-step (brew workflow)

1. Grind your coffee: Grind your beans to a fine consistency, similar to powdered sugar or a bit coarser.

• Good looks like: A consistent, fine powder.
• Common mistake: Grinding too coarse. This leads to weak coffee. Avoid it by checking your grinder setting and making sure it’s set to fine.

2. Heat your water: Bring your filtered water to just off the boil, around 195-205°F.

• Good looks like: Water steaming, but not violently bubbling.
• Common mistake: Using boiling water. This can burn the coffee grounds. Let the water sit for about 30 seconds after it boils.

3. Prepare your brewer: If using a pour-over, rinse your filter. If using a French press, preheat it with a little hot water.

• Good looks like: A clean, ready-to-go brewing device.
• Common mistake: Not rinsing paper filters. This can impart a papery taste. Always give them a quick rinse.

4. Add coffee grounds: Measure your finely ground coffee into your brewer. Use a generous amount for a strong brew.

• Good looks like: A nice bed of coffee grounds, ready for water.
• Common mistake: Under-dosing. This is the fastest way to a weak cup. Eyeball it generously, or use a scale if you’re feeling fancy.

5. Bloom the coffee (optional but recommended): Pour just enough hot water to saturate the grounds, then wait 30 seconds.

• Good looks like: The grounds puff up and release CO2.
• Common mistake: Skipping the bloom. This helps release gases and leads to a more even extraction. Be patient for those 30 seconds.

6. Brew the coffee: Slowly pour the remaining hot water over the grounds, ensuring all are saturated. Brew for 3-4 minutes for French press, or follow your pour-over method.

• Good looks like: A steady stream of dark, aromatic coffee dripping through.
• Common mistake: Pouring too fast. This can lead to channeling, where water bypasses some grounds. Pour in slow, concentric circles.

7. Press or strain: If using a French press, slowly press the plunger. If using a pour-over or strainer, let it finish dripping.

• Good looks like: Clear, concentrated coffee liquid.
• Common mistake: Plunging too hard or fast. This can force fine grounds into your cup. Go slow and steady.

8. Measure condensed milk: Pour a generous amount of sweetened condensed milk into your serving glass. Start with 2-3 tablespoons per serving.

• Good looks like: A thick, sweet liquid ready to be mixed.
• Common mistake: Not using enough. This is Thai coffee, after all. Don’t be shy.

9. Add brewed coffee: Pour your hot, strong brewed coffee over the condensed milk.

• Good looks like: The hot coffee mingling with the thick milk.
• Common mistake: Adding milk first to a cold glass. It won’t mix as well. Use a room-temperature or slightly warmed glass for easier mixing.

10. Stir vigorously: Use a spoon to stir the coffee and condensed milk until fully combined.

• Good looks like: A uniform, creamy, caramel-colored drink.
• Common mistake: Not stirring enough. You’ll end up with pockets of pure condensed milk or unmixed coffee. Stir until it’s all one happy family.

11. Serve over ice: Fill a separate glass with ice and pour the sweetened coffee mixture over it.

• Good looks like: A refreshing, chilled beverage.
• Common mistake: Not using enough ice. Your drink will melt the ice too fast and become watery. Pack that glass full.

12. Taste and adjust: Take a sip. Too sweet? Add a splash more coffee. Not sweet enough? Add more condensed milk.

• Good looks like: A perfectly balanced, delicious drink for you.
• Common mistake: Settling for “okay.” This is your coffee. Make it perfect.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using stale coffee beans	Flat, dull flavor, lack of aroma	Use freshly roasted beans, ideally within a few weeks of roasting.
Incorrect grind size (too coarse)	Weak, watery coffee, poor extraction	Grind finely, similar to espresso or a bit finer. Check your grinder settings.
Incorrect grind size (too fine)	Clogged filter, bitter, over-extracted coffee	Use a slightly coarser grind than espresso, or adjust your brew time.
Brewing with water too cool	Under-extraction, sour or weak coffee	Heat water to 195-205°F. Use a thermometer if needed.
Brewing with water too hot	Scorched coffee, bitter and harsh flavor	Let boiling water sit for 30 seconds before brewing.
Not rinsing paper filters	Papery or chemical taste in the final coffee	Rinse paper filters with hot water before adding coffee grounds.
Under-dosing coffee	Weak, diluted coffee that can’t be saved	Use a higher coffee-to-water ratio (e.g., 1:15 or 1:16, leaning towards more coffee).
Not stirring condensed milk well	Inconsistent sweetness, clumps of milk at the bottom	Stir vigorously until the coffee and milk are fully integrated.
Using tap water with strong flavors	Off-flavors that mask the coffee and sweetness	Use filtered or bottled water for a cleaner taste.
Not cleaning equipment regularly	Rancid oils, bitter or stale coffee taste	Clean your brewer, grinder, and storage containers regularly.

Decision rules (simple if/then)

• If your coffee tastes weak, then increase the amount of coffee grounds you use for the same amount of water, because more coffee means a stronger brew.
• If your coffee tastes bitter, then try a slightly coarser grind or a shorter brew time, because over-extraction makes coffee bitter.
• If your coffee tastes sour, then try a finer grind or a slightly longer brew time, because under-extraction makes coffee sour.
• If your water isn’t hot enough, then reheat it to the 195-205°F range, because proper temperature is crucial for extraction.
• If you’re tasting paper in your coffee, then make sure you’re rinsing your paper filters thoroughly, because this removes the papery taste.
• If the condensed milk isn’t mixing well, then stir more vigorously and ensure your coffee is hot, because heat helps dissolve the milk.
• If the drink is too sweet, then add more brewed coffee or a splash of water, because this dilutes the sweetness.
• If the drink isn’t sweet enough, then add more sweetened condensed milk, because that’s the primary sweetener.
• If your French press coffee is muddy, then try a coarser grind and a slower plunge, because fine grinds can slip through the filter.
• If your pour-over is draining too fast, then try a finer grind, because this slows down the flow rate.
• If your coffee tastes bland, then check the freshness of your beans and ensure you’re using a fine grind, because both are critical for flavor.

FAQ

What kind of coffee beans should I use for Thai coffee?

Medium to dark roasts are generally preferred for their robust flavor, which stands up well to the sweetness of condensed milk. Espresso roast or a good quality dark roast will work nicely.

Can I use evaporated milk instead of condensed milk?

No, you really need sweetened condensed milk. Evaporated milk is unsweetened and much thinner, it won’t provide the signature sweetness and creamy texture of authentic Thai coffee.

How much condensed milk is typical?

It’s really to your taste, but traditionally, it’s quite sweet. Start with 2-3 tablespoons per 6-8 oz serving of coffee and adjust from there. You can always add more.

Is there a non-dairy alternative to condensed milk?

Some brands offer sweetened condensed coconut milk or oat milk. They can work, but the flavor profile will be different from traditional Thai coffee. Experiment to see what you like.

Can I make this ahead of time?

It’s best enjoyed fresh. Brewing the coffee and then mixing it with the condensed milk and serving it over ice right away ensures the best flavor and texture.

What if I don’t have a special coffee brewer?

A strong brew from a standard drip coffee maker or even a Moka pot can work in a pinch. The key is to brew it strong and fine-grind it if possible.

How do I get that authentic “pulled” Thai coffee look?

Traditionally, Thai coffee is brewed using a cloth filter sock and then poured from a height into a glass with condensed milk. This aeration helps create a frothy texture, but it’s mostly for show. The taste will still be great without the fancy pour.

While not essential for taste, if you’re aiming for that authentic ‘pulled’ Thai coffee look, a traditional Thai coffee maker with a cloth filter can be a fun addition to your coffee setup.
