Vietnamese Phin Filter: How to Brew and Adjust Your Cup
Learn the parts of a Vietnamese phin filter, follow a practical brewing sequence and adjust grind, dose and water for the coffee and filter you use.
A Vietnamese phin is a drip filter that rests above a cup or glass. Hot water passes through ground coffee and the perforated base into the cup. You can serve the brewed coffee black, with sweetened condensed milk, hot or over ice.
The useful starting point is your own filter and coffee. Phin sizes and insert designs differ, so record the dose, water and grind rather than expecting one recipe to suit every setup. This guide explains the parts, a brewing sequence and the adjustments to try when the cup or flow needs work.

What Are the Parts of a Vietnamese Phin?
Check the components supplied with your filter and how they fit together:
Follow the instructions for the insert you own. A gravity insert and a screw insert should not be adjusted as if they were identical. Check that the filter rests securely on the cup before adding water.
- Base or drip plate: supports the filter above the cup.
- Chamber: holds the ground coffee and brewing water.
- Insert: sits above the coffee; some designs use a gravity insert and others have a screw mechanism.
- Lid: covers the chamber during brewing.

Choose Coffee and a Repeatable Starting Recipe
Use ground coffee intended for your phin, or grind whole beans for the filter you have. Robusta, Arabica and blends can all be evaluated in the cup; origin or species alone does not establish one flavour or the right grind for every filter.
As a named starting example, Nguyen Coffee Supply’s gravity-phin guide uses 14 g of coffee with 4 US fluid ounces of water, about 120 ml, at 195–200°F, about 91–93°C. It recommends a fine, sand-like grind and a 45-second bloom. This is an example for that setup: check your filter’s capacity and instructions, then adjust the result you taste.
Keep coffee mass and water volume in separate fields in your brew note. For broader product choices, see the Vietnamese coffee FAQ and the MR.VIET coffee catalogue.

How to Brew Coffee with a Phin Filter
1. Prepare the filter and serving.
Assemble the clean filter on a stable cup or glass. If you want sweetened condensed milk in the serving, add your chosen amount to the cup and record it.
2. Measure and level the coffee.
Weigh the coffee for your starting recipe, add it to the chamber and gently level the bed. Record the grind setting if you are grinding beans.
3. Position the insert.
Fit the insert as the filter maker directs. Avoid treating more pressure as an automatic way to improve flavour or correct the flow.
4. Wet the coffee, then add the brewing water.
If your recipe includes a bloom, add the initial water and wait for its specified interval. Continue with the remaining water without exceeding the chamber’s usable capacity. Keep the total water amount in your note.
5. Let the brew drain.
Cover the filter and observe the flow. Record the approximate drain time alongside the dose, grind and water. The time is a diagnostic note for this setup, rather than a universal pass-or-fail rule.
6. Taste and finish the drink.
Remove the filter carefully after brewing. Stir the coffee and condensed milk if used. Taste before adding ice or extra water, then record the finished serving you prefer.

Adjust Grind, Dose and Flow One Step at a Time
If the coffee runs through very quickly, check the dose, grind and insert position against your starting recipe. If the brew stalls, check for blocked holes, an overly fine grind, too much coffee or an insert adjusted differently from its instructions.
Change one variable for the next cup and keep the others recorded. Try a grind adjustment before assuming the filter needs more pressure. Compare the result with the previous brew rather than judging by the clock alone.
Taste is part of the check. Note whether the cup is too weak, too concentrated or unpleasant to you, and whether that changes after milk or ice is added. A slower brew does not automatically taste better.
For repeated cups at a café or tasting, record the coffee, grind, dose, water, filter and serving additions. That gives another person a useful recipe to reproduce and adjust.

Serve Phin Coffee Hot, Black or with Milk and Ice
For a black serving, drink the brewed coffee hot or finish it with ice as you prefer. For cà phê sữa đá, combine coffee with sweetened condensed milk and ice. Keep the milk and ice amounts in the recipe because they change the finished cup.
Vietnam Tourism’s coffee guide describes several café preparations, including drip-filter, iced milk and coconut coffee. Choose a serving to explore rather than assuming all Vietnamese coffee is prepared in one way.
When comparing two coffees, first taste them with the same preparation and then in the drink you intend to serve. Keep the additions the same for that comparison.

Choose the Brewing Format for Your Routine
A phin gives you a manual drip-filter routine with a ground-coffee dose for each brew. Consider the time, cup capacity, cleaning and consistency you need at home or at a café.
Other formats have different preparation steps. Follow the directions and equipment requirements for the product you choose. A phin is useful when that routine fits your serving; it does not guarantee a better flavour than every other brewing method.
For a business tasting, compare the complete workflow as well as the cup: preparation time, portioning, staff instructions and the way the finished drink will be served. Use those observations to choose the coffee format for your customers.

Check the Filter Before Buying
Ask the seller for the filter’s material, usable capacity, insert design and care instructions. Check the cup or glass size it will sit on and whether replacement parts are available if you need them.
Inspect how the chamber, plate, insert and lid fit together. Choose a size that suits the serving and recipe you plan to make. Do not assume that a material name alone proves temperature consistency or the finished cup’s quality.

Clean and Store the Phin and Coffee
Empty the used grounds and clean the filter following its maker’s instructions. Check the perforations and insert for retained grounds, then let the components dry before storage. Follow the material-specific instructions for detergents, abrasives or dishwasher use.
Keep the coffee in its closed pack under the product’s storage directions. The coffee-storage guide covers working packs, beans and ground coffee. A clean filter and a recorded recipe make the next comparison easier to repeat.

Choose Coffee for Your Home or Business Phin Setup
Start with the MR.VIET coffee catalogue and identify the whole-bean or ground-coffee products you want to evaluate. Prepare a sample with your phin and keep the recipe alongside your tasting notes.
For a café, shop or distributor range, send your destination, sales channel, coffee formats, pack needs and expected quantity. Tell the team how the coffee will be prepared so the product and sample discussion fits your intended serving.
