South Indian filter coffee is one of the most distinctive and rewarding coffee rituals in the world. The combination of a perfectly brewed decoction and hot frothy milk, served in a traditional tumbler-davara set, produces a cup that no machine or café can replicate. Here is everything you need to know to make it properly at home.
What you need
- A South Indian metal filter (stainless steel, two-piece)
- Continental Malgudi filter coffee powder — 80/20 blend for a classic cup, 53/47 blend for a stronger, more traditional decoction
- Full-fat milk
- Sugar to taste
- A traditional tumbler and davara (or any cup and saucer)
The decoction — step by step
- Measure the coffee powder — add 2–3 tablespoons (approximately 20–25g) of Continental Malgudi to the upper compartment of the filter. The exact amount depends on how strong you like your decoction. Start with 2 tablespoons and adjust after tasting.
- Press lightly — use the pressing disc to gently compact the powder. Do not press hard — you want water to flow through, not get blocked. A light press is enough.
- Add hot water — pour approximately 80–100ml of water that has just come off the boil over the powder. Fill to just below the rim.
- Cover and wait — place the lid on top and allow the decoction to drip through for 10–15 minutes. Do not rush this. The slow drip is what gives South Indian filter coffee its characteristic thick, concentrated character.
- Check the decoction — the liquid that collects in the lower chamber should be dark brown, almost black, and thick. If it is very watery, you used too little coffee or too much water.
The milk — how to get the froth right
Heat full-fat milk in a pan until it is hot but not boiling — you want it steaming, with small bubbles forming at the edges. Full-fat milk is non-negotiable for authentic South Indian filter coffee. Skimmed or low-fat milk will not produce the same creamy body.
The traditional frothing method is the tumbler-davara technique — pour the coffee from a height between the tumbler and the davara several times until a thin layer of foam forms on top. This aerates the coffee and cools it to drinking temperature simultaneously. It takes practice but is enormously satisfying once you get it right.
Assembly
Add sugar to the tumbler first if using. Pour a small amount of decoction — typically 20–30ml for a standard cup. Top with 150–180ml of hot milk. Mix by pouring between tumbler and davara 3–4 times. The ratio of decoction to milk is a matter of personal taste — start with 1:5 (decoction to milk) and adjust.
Which Malgudi blend should you use?
The 80/20 blend (80% coffee, 20% chicory) is the best starting point for most people. It produces a full-bodied decoction with a clean chicory finish that works beautifully with milk. The 53/47 blend has more chicory — stronger, more bitter, and more traditional. If you grew up in a South Indian household, the 53/47 is likely closer to what you remember.

Common mistakes and how to fix them
- Decoction is too watery — use more coffee powder or less water
- Decoction takes too long to drip — the powder is packed too tightly or the grind is too fine for your filter
- Coffee tastes bitter — water was too hot or you used too much powder. Let the boiled water rest for 30 seconds before pouring
- No froth — use full-fat milk and pour from a greater height between tumbler and davara
The Malgudi Twin Pack gives you both the 80/20 and 53/47 blends together — perfect for experimenting with your ratio and finding your ideal decoction strength.
