The right coffee, water, and condensed milk for your Vietnamese phin, measured the way it’s actually made. Pick your cup, pick your style, and start the drip.
A phin is a small metal filter that sits right on top of your cup. No paper, no pump, no machine. You add ground coffee, rest a perforated press on top, pour in hot water, and gravity does the rest, one slow drip at a time. The whole brew takes around five minutes, and honestly, the waiting is part of the drink.
Because the water sits with the grounds the entire time, phin coffee lands somewhere between espresso and French press: thick, strong, and full of body, with the fine oils and sediment a paper filter would strip out. Vietnamese coffee is traditionally robusta, which is bolder and more bitter than the arabica most cafés pour, and that intensity is exactly why sweetened condensed milk became its lifelong partner.
The catch: a phin has no dials. Your only controls are how much coffee you use, how it’s ground, how hard the press sits, and how much water you pour. Get the ratio right and everything else falls into place, which is the whole point of this page.
black coffee
Just coffee and hot water, nothing to hide behind. Hot (đen nóng) it’s intense and almost syrupy; over ice (đen đá) it turns bright and bittersweet. If you drink espresso straight, start here.
Coffee + water. Maybe ice.
The ratio, explained →hot with condensed milk
A spoonful of sweetened condensed milk waits at the bottom of the cup while the phin drips on top. Stir when it’s done and the bitterness and sweetness meet in the middle. The cold-morning order.
Milk in first, brew on top, stir.
Brewing steps →iced with condensed milk
The one everybody knows. Brewed strong on purpose, because the ice will water it down as you sit with it. Stir it well, pour it over a full glass of ice, and take your time.
Strong brew + milk, poured over ice.
Full recipe →milk with a splash of coffee
A Saigon classic that flips the ratio: mostly milk, gently touched by coffee. Sweet, soft, and dangerously easy to drink. The move for people who "don’t drink coffee," and for your second cup of the day.
Lots of milk, a little coffee, ice.

A good starting point is about 1:5, roughly 20–25 g of coffee for 100–120 ml of brewed coffee. That’s far stronger than drip coffee (usually 1:15 or weaker) because phin coffee is meant to be a small, concentrated cup, often cut with condensed milk or ice. Going iced? Brew closer to 1:4 so the melting ice doesn’t wash it out.
Medium: a little coarser than you’d use for a paper pour-over, finer than French press. Too fine and the drip stalls or stops entirely; too coarse and water races through, leaving a thin, sour cup. If you buy Vietnamese coffee ground for phin (Trung Nguyên, for example), it’s already right.
Almost always the grind is too fine, or the gravity press got compacted when you poured. Try lifting or loosening the press a touch with a spoon handle to restart the drip. Next brew, grind a step coarser and pour the bloom water gently instead of dumping it in.
Traditional Vietnamese phin coffee is robusta. It’s bolder, more bitter, has nearly twice the caffeine, and stands up to condensed milk the way arabica can’t. That said, plenty of people brew arabica or a blend in a phin and love it. If it’s your first time, try a Vietnamese robusta or a robusta-forward blend to taste what the drink is built around.
Any sweetened condensed milk works. The key word is sweetened, not evaporated milk. In Vietnam the classic brands are Longevity and Ông Thọ; abroad, whatever your grocery store carries is fine. Adjust to taste: the calculator’s numbers are a starting point, and nobody will check your measurements.
Around 4–6 minutes total: let the grounds bloom in a splash of hot water for 30–40 seconds, then fill the chamber and let it drip. Under 3 minutes usually means the grind is too coarse or the dose too small; much past 7 minutes and it starts over-extracting into harsh territory.
Just off the boil, about 92–96°C (198–205°F). Boil your kettle, give it 30 seconds to settle, then pour. Water that’s still violently boiling scorches the grounds; water that’s too cool under-extracts and stalls the drip.
Most home phins are 4 oz (~120 ml through the chamber) and suit 15–25 g of coffee, which covers the small and classic cup sizes here. Bigger 8–12 oz phins exist for larger cups or sharing. If your dose won’t fit under the press with room for water, brew in two rounds or size up your phin.
