What to check first

Brewer type and filter type

The type of brewer you use will significantly impact the texture and clarity of your coffee. While a traditional Vietnamese phin filter is designed for a slow, concentrated drip, other methods can achieve a similar strength.

• French Press: This immersion method will produce a full-bodied coffee with some sediment.
• Pour-over (with paper filter): This will yield a cleaner cup, similar to what a phin filter aims for, but the flow rate will be faster.
• Makeshift Strainer: Using a fine-mesh sieve lined with a paper towel or cheesecloth can work in a pinch, but requires patience.

If you’re aiming for a cleaner cup, a pour-over cone with a paper filter is a great alternative to a phin filter. This method will yield a cleaner cup, similar to what a phin filter aims for.

Water quality and temperature

Good water is crucial for good coffee. Using filtered water will remove impurities that can affect taste. For hot coffee, aim for a water temperature between 195-205°F (90-96°C). Water that is too cool will lead to under-extraction, resulting in a weak and sour coffee. Water that is too hot can scorch the grounds, leading to a bitter taste.

Grind size and coffee freshness

The grind size is paramount for proper extraction. For methods like French press, a medium-coarse grind is ideal. If using a pour-over with a paper filter, a medium grind is usually best. For a makeshift strainer, a slightly coarser grind might prevent clogging. Freshly roasted and ground coffee will offer the most vibrant flavors. Pre-ground coffee loses its aroma and taste quickly.

Coffee-to-water ratio

Vietnamese coffee is known for its strength. A common starting point is a ratio of 1:5 or 1:6 (coffee to water by weight). For example, if you’re using 20 grams of coffee, you might start with 100-120 grams of water. This will create a concentrated base that stands up well to the sweetness of condensed milk.

Cleanliness/descale status

A clean brewing device is essential. Any residual coffee oils or mineral buildup from previous brews can impart off-flavors. Regularly clean your brewer according to the manufacturer’s instructions. If you have a machine that uses water, ensure it’s descaled periodically to maintain optimal performance and taste.

Step-by-step (brew workflow)

Here’s a general workflow for making Vietnamese coffee without a phin filter, adaptable to a French press or pour-over:

1. Heat Your Water: Bring filtered water to a temperature between 195-205°F (90-96°C).

• What “good” looks like: Water is steaming but not vigorously boiling.
• Common mistake: Using boiling water directly, which can scald the coffee. Let it rest for about 30-60 seconds after boiling.

2. Prepare Your Grounds: Measure your coffee beans and grind them to a medium-coarse consistency (for French press) or medium (for pour-over).

• What “good” looks like: Grounds are uniform in size.
• Common mistake: Using a grind that’s too fine (like for espresso), which can lead to over-extraction and bitterness, or clog filters.

3. Preheat Your Brewer: If using a French press or pour-over cone, rinse it with hot water.

• What “good” looks like: The brewer is warm to the touch.
• Common mistake: Skipping this step, which can lead to a drop in brewing temperature and uneven extraction.

4. Add Coffee Grounds: Place the measured coffee grounds into your preheated brewer.

• What “good” looks like: Grounds are evenly distributed at the bottom.
• Common mistake: Tamping down the grounds, which restricts water flow.

5. Bloom the Coffee (Pour-over/French Press): Pour just enough hot water (about twice the weight of the coffee) over the grounds to saturate them. Let it sit for 30 seconds.

• What “good” looks like: The grounds expand and release CO2, creating a bubbly surface.
• Common mistake: Pouring all the water at once, which can lead to channeling and uneven extraction.

6. Add Remaining Water: Slowly pour the rest of the hot water over the grounds. For French press, fill to just below the spout. For pour-over, pour in slow, concentric circles.

• What “good” looks like: Water is distributed evenly, saturating all grounds.
• Common mistake: Pouring too quickly or unevenly, which can create dry pockets or wash grounds away from the filter.

7. Steep and Brew (French Press): Place the lid on the French press without pressing down the plunger. Let it steep for 4 minutes.

• What “good” looks like: Coffee is steeping at the correct temperature.
• Common mistake: Pressing the plunger too early or too late, affecting extraction time.

8. Press the Plunger (French Press): Slowly and steadily press the plunger all the way down.

• What “good” looks like: The plunger moves smoothly without excessive resistance.
• Common mistake: Forcing the plunger down, which can cause grounds to bypass the filter and make the coffee gritty.

9. Drip and Finish (Pour-over): Allow all the water to drip through the grounds. This usually takes 2-4 minutes depending on the grind and pour rate.

• What “good” looks like: The coffee bed is mostly dry after brewing.
• Common mistake: The brew finishing too quickly (under-extracted) or taking too long (over-extracted).

10. Combine with Condensed Milk: Pour your strong brewed coffee into a glass. Add sweetened condensed milk to taste. A common starting point is 1-2 tablespoons of condensed milk per 4-6 oz of coffee.

• What “good” looks like: The condensed milk is well incorporated, creating a creamy, sweet base.
• Common mistake: Not stirring enough, leaving pockets of unmixed milk.

11. Serve Over Ice: Fill a tall glass with ice cubes. Pour the sweetened coffee mixture over the ice.

• What “good” looks like: The ice chills the coffee without diluting it too quickly.
• Common mistake: Using lukewarm coffee, which melts ice too fast and results in a watery drink.

12. Stir and Enjoy: Stir the iced coffee until well chilled and blended.

• What “good” looks like: A refreshing, perfectly balanced sweet and strong coffee.
• Common mistake: Not stirring enough, leading to inconsistent sweetness and temperature.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes bitter, then reduce the brew time or use a slightly coarser grind because over-extraction is likely.
• If your coffee tastes sour and weak, then increase the brew time or use a slightly finer grind because under-extraction is likely.
• If you are using a French press and the coffee is gritty, then press the plunger more gently and ensure your grind is not too fine because grounds are likely bypassing the filter.
• If your pour-over is brewing too fast, then use a finer grind because water is flowing through too quickly for proper extraction.
• If your pour-over is brewing too slowly, then use a coarser grind because the grounds are too fine and restricting water flow.
• If you find the coffee too sweet, then use less sweetened condensed milk or a bit more brewed coffee because the sweetness level is personal preference.
• If you find the coffee not sweet enough, then add more sweetened condensed milk because the sweetness level is personal preference.
• If your coffee tastes “off” or stale, then check the freshness of your coffee beans and ensure your brewing equipment is clean because these are common culprits.
• If you want a cleaner cup with less sediment, then opt for a pour-over method with a paper filter over a French press because paper filters trap more fine particles.
• If you prefer a bolder, more full-bodied coffee and don’t mind a little sediment, then a French press is a good choice because it’s an immersion method.
• If your brewed coffee is too concentrated even after brewing, then you can add a small amount of hot water to dilute it slightly before adding condensed milk and ice.
• If you are in a hurry and want a quick strong coffee base, consider a Moka pot if you have one, though it requires a finer grind.

FAQ

Q: Can I use any type of coffee bean?

A: While you can use any roast, Vietnamese coffee traditionally uses dark-roasted beans, often with Robusta. Experiment with different roasts to find what you prefer.

Q: How much sweetened condensed milk should I use?

A: This is entirely to your taste! A good starting point is 1-2 tablespoons per 4-6 oz of brewed coffee. Taste and adjust until you reach your desired sweetness and creaminess.

Q: What if I don’t have a thermometer for my water?

A: If you don’t have a thermometer, bring your water to a full boil, then let it sit off the heat for about 30-60 seconds. This usually brings it into the ideal brewing temperature range.

Q: My coffee is too weak. What did I do wrong?

A: This usually means under-extraction. Try using a finer grind, brewing for a bit longer, or using a bit more coffee relative to your water. Ensure your water temperature is also within the correct range.

Q: My coffee is too bitter. What did I do wrong?

A: This often points to over-extraction. Try using a coarser grind, brewing for a shorter time, or ensuring your water isn’t too hot. A common mistake is using a grind that’s too fine for the brew method.

Q: Can I make this iced coffee ahead of time?

A: It’s best to brew the coffee and mix it with condensed milk just before serving over ice. Pre-brewing and storing might affect the freshness and flavor.

Q: What’s the difference between Vietnamese coffee and regular iced coffee?

A: The key difference is the use of sweetened condensed milk, which provides a unique creamy texture and sweetness that regular iced coffee typically doesn’t have.

Q: Can I use regular milk instead of condensed milk?

A: You can, but it won’t produce the authentic Vietnamese coffee flavor and texture. Sweetened condensed milk is crucial for that signature taste. You might need to add sugar separately if using regular milk.
