The Vietnamese phin is a small slow-drip metal filter that sits on top of a glass. Coffee grounds plus boiling water, gravity, 4-5 minutes of dripping. The result is intensely concentrated, somewhere between espresso strength and a thick syrup, with a flavour distinct from both. Behind the bar, it solves a specific problem that espresso and cold brew cannot.
How the phin differs from other coffee
vs espresso: phin coffee is similarly concentrated but has more body and less crema. Espresso brings sharpness; phin brings depth without the sharp edge.
vs cold brew: phin has the same low-acid character as cold brew, but with more intensity per millilitre. Cold brew is a long-format ingredient; phin is a small-format one.
vs drip / pour-over: phin is roughly 3-4x more concentrated than standard drip. You use a third of the volume in a cocktail build.
The flavour signature: dark chocolate, slight smoke, mild bitterness, surprising sweetness. Vietnamese phin coffee is traditionally Vietnamese robusta, which adds the chocolate-and-tobacco character that distinguishes it from Latin American arabica.
Why it works in cocktails
Two reasons:
1. Concentration without dilution. A 15ml dose of phin coffee adds the flavour of a full espresso shot in half the volume. Useful when you do not want extra liquid in the build.
2. The Vietnamese-coffee context. Traditional Vietnamese coffee is drunk with condensed milk (ca phe sua) or as a coconut-coffee blend (ca phe dua). Both pair beautifully with rum, aged spirit, or vodka in a cocktail format.
How to brew phin for cocktails
- Use a Vietnamese phin filter (available in any KL Vietnamese restaurant or Asian grocery for RM 15-25).
- Add 12g of medium-coarse-ground Vietnamese-style robusta to the filter.
- Pre-wet with 10ml of hot water; wait 30 seconds for bloom.
- Add 60ml of just-off-boil water.
- Cover the filter. Wait 4-5 minutes for the drip to complete.
- Yield: ~50ml of concentrated coffee.
- Cool before adding to cold cocktails.
For bar use, brew during slow hours and bottle in the fridge. Lasts 4-5 days before losing intensity.
Three drinks built on phin coffee
1. Ca Phe Sua Old Fashioned. Bourbon (45ml), condensed milk syrup (15ml, combine 1:1 condensed milk and warm water), phin coffee (15ml), chocolate bitters (2 dashes). Stir over a large ice cube. The Vietnamese sweetened-coffee tradition in spirit form.
2. Coconut-Phin White Russian. Vodka (40ml), coffee liqueur (25ml), phin coffee (15ml), coconut cream (15ml). Build over ice or shake and strain. The ca phe dua (coconut Vietnamese coffee) reimagined as a cocktail.
3. Phin Espresso Martini variant. Vodka (45ml), coffee liqueur (25ml), phin coffee (20ml, replaces standard espresso), gula melaka syrup (10ml). Shake hard. Double-strain. Reads deeper and more bitter than the standard Espresso Martini.
Sourcing in Malaysia
Vietnamese-grown robusta is available at the larger Asian groceries and Vietnamese supermarkets in KL (try Lazada or any Vietnamese restaurant that retails their house bean). RM 25-40 per 250g packet. Trung Nguyen is the best-known brand but the more interesting beans come from smaller co-ops.
Phin filters: any Vietnamese restaurant in KL/PJ sells them for RM 15-25. The metal ones last forever; the stainless-steel premium ones (~RM 80) drip more evenly.

Frequently asked questions
What is Vietnamese phin coffee?
The phin is a small slow-drip metal filter that sits on top of a glass. Coffee grounds plus boiling water, gravity, 4 to 5 minutes of dripping yields about 50ml of intensely concentrated coffee, somewhere between espresso strength and a thick syrup. Traditionally Vietnamese robusta is used, giving a dark chocolate, slight smoke, mild bitterness, and surprising sweetness, distinct from Latin American arabica.
How do I brew phin coffee for cocktails?
Add 12g medium-coarse-ground Vietnamese robusta to the phin filter. Pre-wet with 10ml hot water and wait 30 seconds for the bloom. Add 60ml just-off-boil water and cover. Wait 4 to 5 minutes for the full drip; yield is about 50ml. Cool before adding to cold cocktails. For bar use, brew during slow hours and bottle in the fridge; it keeps 4 to 5 days before losing intensity.
How is phin coffee different from espresso in a cocktail?
Phin coffee is similarly concentrated but has more body, less crema, and no sharp edge. Espresso brings high-pressure sharpness and a bright crema; phin brings depth and chocolate-tobacco character without intensity. A 15ml phin dose adds the flavour of a full 30ml espresso shot in half the volume, useful when you do not want extra liquid in the build, like in an Old Fashioned or stirred drink.
Can I substitute phin coffee for espresso in an Espresso Martini?
Yes, and the swap shifts the drink's character. Replace the espresso with 20ml of cooled phin coffee and add a touch of gula melaka syrup for sweetness. The result reads deeper, more bitter, and slightly more chocolate-forward than the standard Espresso Martini. The traditional Vietnamese ca phe sua (coffee with condensed milk) framing also adapts beautifully into an Old Fashioned with bourbon and chocolate bitters.
Where can I source Vietnamese phin filters and coffee in KL?
Phin filters: any Vietnamese restaurant in KL or PJ sells them for RM 15 to 25 (RM 80 for premium stainless steel). Vietnamese-grown robusta beans at larger Asian groceries, Vietnamese supermarkets, or Lazada, RM 25 to 40 per 250g. Trung Nguyen is the best-known brand. To try phin cocktails, ask off-menu at Dissolved Solids or Soluble Solids; we keep the phin on rotation.
