Phin

The phin is the small stainless steel drip filter behind classic Vietnamese coffee. It has four parts: a base plate that sits on the cup, a chamber that holds the grounds, a perforated press that tamps and covers the bed, and a lid. You add a coarse-to-medium grind, settle the press on top, pour a little hot water to wet the bed, then fill and wait while it drips through.

Why it matters: the phin is a slow percolation brew that produces a small, concentrated, syrupy cup, often using dark-roasted robusta for punch and body. The classic serve is cà phê sữa đá, the brew dripped straight onto a spoonful of sweetened condensed milk, then stirred and poured over ice. That family of drinks is close cousin to Indonesian kopi-susu.

The phin is forgiving and needs no paper filter or scale, but it rewards attention: pack the bed evenly and tune grind size so the drip takes roughly four to five minutes rather than rushing through.
