    Tools You’ll Need

    To brew traditional Vietnamese iced coffee, you’ll need the following items/ingredients: 

    1. Traditional Phin Filter — This small metal device is the go-to brewing method for all Vietnamese coffee. It requires no filters and no electricity.
    2. High-Quality Coffee — We recommend fresh-roasted, high-quality robusta coffee for best results (try our SaiGon OG). All our ground coffee comes in the perfect grind size for making iced Vietnamese coffee.
    3. Coffee Grinder — We prefer using a burr grinder to ensure an even grind, but cheaper blade grinders work fine too. If you buy pre-ground coffee you can skip this tool.
    4. Boiling Water — Even though you’re making iced coffee, it still has to steep hot.
    5. Ice — A critical step for brewing iced coffee! Keep enough ice handy to fill your cup.
    6. Sweetened Condensed Milk (Or Dairy-Free Alternative) — The traditional recipe calls for sweetened condensed milk, but there are plenty of great dairy-free options available these days too.

    Detailed Step-By-Step Instructions: Vietnamese Iced Coffee

    There’s no need to overcomplicate things, Vietnamese coffee consists of strong concentrated coffee poured over ice and mixed with your sweetener of choice.

    Here’s the traditional recipe, delivered straight from the streets of Vietnam.

    1. Measure & Grind Your Coffee

    Phin filters work best with a fine grind. Opt for a consistency similar to sand.

    For a standard 4 oz phin (120 mL), you should weigh out 2 tablespoons of coffee (14 grams). This will produce one cup of coffee.

    For larger batches, use a larger phin filter (6 or 8 oz) with 3 or 4 tablespoons, respectively.

    2. Assemble Your Phin Filter

    The phin filter consists of 4 components. The filter tray goes on the bottom, placed on top of your cup.

    Add the chamber on top — this is where you’ll place your coffee grounds and pour the water.

    Set the gravity press and lid to the side for now.

    3. Tamp Your Coffee Grounds With The Gravity Press

    Give the chamber a light shake to even the grounds out. Add the gravity press and press down lightly to tamp the coffee.

    This ensures the grounds are evenly spaced so the water extracts your coffee more efficiently.

    4. Add Boiling Water

    Add just enough water to cover the gravity press. This is called the bloom stage. The bloom is important to get the best flavor from your coffee.

    Wait 45 seconds for all the gases to escape from between your grounds. You should notice some bubbling.

    After 30-seconds, add the rest of your water. Fill the phin to just below the top of the filter. Add the lid while the brew steeps to keep the heat in.

    You should start to see drops of coffee after about 1 minute. The final drop should take about 5–7 minutes.

    5. Add Ice, Sweetener, & Stir

    Remove your phin, add enough ice to fill the cup, and stir in your sweetener of choice.

    Traditional Vietnamese iced coffee typically calls for 2 tablespoons of condensed milk. 

    Dairy-free sweeteners or liquid sugar are great alternatives. Feel free to alter the amount of sweetener you use to match your desired taste, or skip the sweetener altogether.

    What Is a Phin Filter?

    Phin filters are a key tool in making Vietnamese coffee. They're the traditional filtering method and remain popular due to their even, concentrated extraction. They're typically made from aluminum or stainless steel, eliminating the need for paper filters, electricity, and other equipment. 

    Phin filters come in various sizes ranging from 4 oz to 24 oz.

    If you don’t already have a phin filter, you can pick one up in our online shop. We recommend the 4 oz for single-serving sizes, and the 6 or 8 ounce for preparing more than one cup at a time.

    Phin filters have four components:

    1. Drip plate
    2. Brew chamber
    3. Gravity or screw press
    4. Lid

    Other Methods For Brewing Vietnamese Iced Coffee

    While the method outlined above follows the traditional process used by the Vietnamese, there are other methods you can use depending on the tools you have at home.

    1. French Press Vietnamese Iced Coffee

    Brew a strong pot using 2 tablespoons of coffee (14 grams) of fine-ground coffee and 1.3 ounces (40 grams) of boiling water. Let it steep for 5 minutes before plunging and pouring over ice.

    2. Espresso Vietnamese Iced Coffee

    Brew 1–2 espresso shots, mix with ice, sweeten, and enjoy.

    3. AeroPress Vietnamese Iced Coffee

    Fill your AeroPress with 2 scoops of fine-ground coffee, fill up to the second line, steep for 2 minutes, and press through the filter using the plunger. Ice an sweeten as usual.

    4. Moka Pot Vietnamese Iced Coffee

    Use your moka pot as usual — fill the chamber up to the pressure valve with water, fill the basket with coffee, brew over the stove, and pour over ice and sweetener.

    FAQs & Troubleshooting: Vietnamese Iced Coffee

    1. What kind of coffee should I use for Vietnamese iced coffee?

    Traditional Vietnamese coffee calls for a strong, dark-roast robusta. Our SaiGon OG and HaNoi blend to provide the ideal bold, roasted coffee flavor to Vietnamese iced coffee.

    You can also use arabica beans, such as our DaLat, but it won’t be as strong.

    2. Can I make Vietnamese coffee without a Phin filter?

    Absolutely! While the phin is the best way to make traditional Vietnamese coffee, there are plenty of other methods you can use, too. The goal when preparing Vietnamese coffee is to brew it as strong as possible. Methods like the French press, AeroPress, moka pot, and espresso can all be used to brew strong dark coffee. 

    Mix with ice and/or condensed milk, and you’ve got a delicious cup of Vietnamese coffee.

    Discover alternative methods for brewing Vietnamese coffee if you don't have a phin filter and how these methods compare in terms of flavor and authenticity.

    3. How much sweetened condensed milk should I use?

    This is a matter of preference, but generally, traditional recipes call for about 2 tablespoons of sweetened condensed milk for every 4 ounces of coffee. Adjust to taste — some like it sweeter, others prefer just a hint of sweetness.

    4. What type of ice should I use?

    Crushed ice will cool your coffee more quickly, but also dilutes the coffee with water faster. Large ice cubes allow you to sip your coffee more slowly before it melts and dilutes the coffee. 

    We like to meet in the middle with medium-sized ice cubes. Give your drink a good stir for about 30 seconds and give it a minute to cool down before drinking.

    5. Can I make Vietnamese iced coffee without ice?

    The only way to avoid using ice for iced Vietnamese coffee is to brew your coffee ahead of time and keep it in the fridge for a few hours before mixing it with sweetener. Concentrated cold brew coffee works well using this method, but may lack some of the characteristic flavors of traditional iced coffee.

    6. Can I use regular milk or cream instead of sweetened condensed milk?

    Yes, but this isn’t the traditional method. Milk or creamer of any kind will work to curb the bold flavor of robusta coffee. Some people prefer to add some sugar if using liquid milk or creamer.

    7. Can I use Cafely’s Ready-To-Drink coffees to make Vietnamese iced coffee?

    Yes! Our cold brew milk coffee, black coffee, and coconut coffee make a delicious cup of iced coffee. Store the cans in the fridge to pre-cool and pour over ice to serve.

    8. Can Vietnamese coffee be made vegan?

    You bet! You can swap condensed milk for a thick coconut creamer or any other non-dairy, vegan-friendly sweeteners — or skip the sweetener altogether and drink it black.
