How to make authentic South Indian filter coffee

There is no machine and no rush to it. A steel filter, a spoon of freshly ground coffee, a slow drip of dark decoction, and hot milk pulled back and forth until it froths — this is the coffee that has come out of Mysuru kitchens for generations. Here is how we make it, the way we have since 1945.

• A South Indian steel coffee filter — the two-part davara-tumbler style, with an upper cup, a pressing disc and a lower cup.
• Freshly ground filter coffee powder — our house blend, ground fine for filter (not espresso-fine, not coarse).
• Hot, near-boiling water.
• Whole milk, brought to a boil.
• Sugar or jaggery, to taste.
• A davara and tumbler (the wide steel dish and beaker) for mixing and cooling.

The filter has two chambers. The upper cup has a perforated base; you spoon the coffee in there and press it gently with the disc. The lower cup sits below and catches the decoction as it drips. It is simple, unhurried, and it asks nothing of you but a little patience while it does its work.

A good starting measure is one heaped tablespoon of coffee powder per cup of the finished decoction. For a stronger, more traditional cup, use a little more. Because our blend carries chicory, the decoction runs dark and holds its body well, so you need less powder than you might expect.

New to chicory? Our companion guide on coffee & chicory ratios explains how each ratio changes the cup.

1. Fill the upper cup. Add the coffee powder to the upper chamber. Level it, but do not pack it — coffee needs room to bloom.
2. Press gently. Set the pressing disc on top and press lightly. A firm-but-not-tight bed lets the water pass evenly.
3. Pour hot water. Pour near-boiling water over the disc until the upper cup is full. Set the lid on top.
4. Wait. Let it drip slowly — anywhere from ten to twenty minutes. A slow drip means a rich decoction; if it rushes through, the grind is too coarse or the bed too loose. This dark, concentrated liquid in the lower cup is your kashaya — the decoction.

Do not rush the drip by pressing hard or poking the bed. Let gravity and time do it.

1. Heat the milk. Bring whole milk to a rolling boil — hot milk is what gives South Indian coffee its comfort and froth.
2. Measure the decoction. Pour a small quantity of decoction into your tumbler. Roughly one part decoction to three or four parts hot milk is a good place to begin; adjust to taste over time.
3. Add sugar. Stir in sugar or jaggery while everything is hot, so it dissolves fully.
4. Froth it. Now the flourish — pour the coffee from the tumbler into the davara and back, held high, again and again. Each pour aerates the coffee, cools it to sipping temperature, and raises the signature blanket of froth on top.

Serve it hot in the steel tumbler, resting in its davara. The froth should stand proud at the rim. Sip it while it steams — filter coffee is meant to be drunk fresh, not left to sit. That first sip, dark and milky and just sweet enough, is the whole point of the patience.

• Grind matters. Too coarse and the water runs straight through, thin; too fine and it clogs. A proper filter grind drips slow and steady.
• Freshness matters more. Decoction is only as good as the powder. Keep your coffee airtight and cool — see our guide on storing ground coffee.
• Make decoction fresh. It is at its best within a few hours. If you must keep it, refrigerate and use the same day.
• Adjust to your taste. More decoction for strong, more milk for mild. The measures here are a starting point, not a rule — every household has its own hand.
