How to make South Indian filter kaapi

7 min read

Put about 3 heaped tablespoons (20–25 g) of fine kaapi powder in the top chamber of a steel filter, press lightly, and pour in about 100–120 ml of boiling water. Let it drip for 15–20 minutes. Mix 1 part decoction with 2–3 parts hot milk and sugar to taste, then froth it between a dabara and tumbler.

Filter kaapi is the everyday coffee of Tamil Nadu, Karnataka and much of the south. It is brewed in a two-part steel filter: the top chamber with a perforated base holds the powder, and the decoction slowly drips into the lower cup. Read more about its history in our kaapi primer.

With chicory or without?

	Pure coffee	With chicory
Common blends	100% coffee	About 80:20 or 70:30 coffee to chicory
Taste	Cleaner, more coffee flavour	Darker, thicker, slightly bitter-sweet
Decoction	Lighter in colour	Darker and heavier, goes further with milk
Best for	Less milk, lighter kaapi	Traditional strong milky kaapi

Neither is more correct. Chicory is a roasted root, not coffee, and it was originally used to stretch coffee. Many families now simply prefer the body it brings.

Making the decoction

Boil fresh water. Kaapi needs water at a full rolling boil.
Add 20–25 g of kaapi powder to the upper chamber of a medium filter. Tap to level.
Place the pressing disc on top and press gently. Do not pack it hard.
Pour boiling water up to the brim, about 100–120 ml, and close the lid.
Leave it to drip for 15–20 minutes. Do not lift the top chamber early.
The first decoction is the strongest. You can pour a second round of water for a weaker second decoction.

Making the kaapi

Heat milk until it just starts to rise. Full-fat milk gives the classic texture.
Put sugar in the tumbler, then add 1 part decoction.
Add 2–3 parts hot milk.
Pour between the tumbler and dabara from a height a few times to cool and froth it.
Serve in the tumbler, set inside the dabara.

Tip: Kaapi powder goes stale fast once opened. Buy small packs or whole beans ground fine, and keep them sealed away from humidity, especially in the monsoon.

Troubleshooting

Symptom	Likely cause	Fix
Drips for 30+ minutes or stops	Powder too fine or packed too hard	Press lightly, try a slightly coarser powder
Decoction drips through in 5 minutes	Powder too coarse or too little	Use more powder or a finer grind
Weak kaapi	Not enough decoction or water not boiling	Use boiling water, less milk
Very bitter	Too much chicory or a very dark roast	Try a lower-chicory or pure coffee blend
Flat and dull	Stale powder	Use freshly ground coffee, check the roast date
