Move the sliders. Everything else updates — ratio, bloom volume, grind, water temperature and how long the drip should take. These are starting points drawn from how phin coffee is normally brewed, not measurements of your particular coffee.

Set your dose and water; everything below updates. These are starting points, not rules — grind, coffee density, filter design and how hard you screw down the press all move the result.

    Just enough to wet the bed. Wait 30–45 seconds while the grounds swell.

    Pour the remaining 80 ml

    One pour, lid on, and leave it alone.

    Much faster and the grind is too coarse or the press too loose; much slower and it is the opposite.

The range most Vietnamese cafés work in. Strong enough to survive milk and ice, drinkable black if you like it heavy.

How to Use a Vietnamese Phin Filter

The phin is the Vietnamese coffee filter: 20 g, 100 ml, four to six minutes. The whole method, and what to change when the drip stalls or races.

Phin Coffee Ratio: Why 1:5, and When to Break It

The Vietnamese phin ratio is about 1:5 — far stronger than filter coffee. Why that number exists, what it does to the cup, and the ratios to use instead.

A phin wants a medium-coarse grind, roughly the texture of coarse sand — finer than French press, much coarser than espresso. How to judge it and how to adjust.
