South Indian filter coffee vs Vietnamese phin
Two slow metal drips that both end in sweetened milk — and differ in almost every decision in between, starting with whether the coffee is brewed into the glass or into a batch.
| Aspect | South Indian filter coffee | Vietnamese phin coffee |
|---|---|---|
| What is brewed | A batch of concentrated decoction, made in advance and used across several cups | One serving, brewed directly into the glass it will be drunk from |
| Grounds | Coffee blended with 10-30 per cent roasted chicory, medium-fine | Dark-roasted robusta, medium-coarse |
| Milk | Hot fresh full-fat milk, three to four times the volume of the decoction | Sweetened condensed milk, placed in the glass before brewing |
| Aeration | Pulled repeatedly between tumbler and dabara, which cools, mixes and foams it | Stirred; no aeration step |
| Brewing time | 10-20 minutes for the decoction | 4-6 minutes |
| Caffeine | Reduced by chicory displacing coffee in the blend, then diluted heavily with milk | High — robusta carries roughly twice the caffeine per gram of arabica, at a 15-25 g dose |
Which should you choose?
They look alike in a photograph and are built on opposite logics. The Indian filter separates brewing from serving so a household can make coffee twice a day from one batch of decoction; the phin collapses the two so a café can make one glass at a time in front of you. If you want the stronger cup by caffeine, it is the phin, and not by a small margin.
