Preparation method — India
South Indian filter coffee
A concentrated decoction dripped slowly through a two-chamber metal filter, then mixed with hot milk and sugar and pulled repeatedly between a tumbler and a dabara until it froths.

What it is
South Indian filter coffee is two processes that are usually described as one. The first is the decoction: coffee, typically blended with roasted chicory, is packed into the upper chamber of a metal filter, pressed down with a disc, and left to drip through into the lower chamber over ten to twenty minutes. The result is a small volume of very concentrated liquid that nobody drinks as it is.
The second is the mixing, and it is where the drink actually gets made. Decoction, hot milk and sugar go into a tumbler, and the mixture is poured back and forth between the tumbler and a wide-lipped bowl called a dabara — pulled apart to arm's length, so the stream aerates as it falls. This cools the coffee to drinkable temperature, dissolves the sugar, and whips a light foam onto the top. A cup made without the pulling is recognisably not the same drink.
Chicory is not an adulterant here, whatever its history elsewhere. A blend of roughly 80 parts coffee to 20 chicory is the common default, with 70:30 and 90:10 both normal, and the chicory contributes body, colour and a particular bitterness that regular drinkers expect and miss when it is absent.
What makes it distinct: Aeration by hand-pouring between two vessels, doing the job that a steam wand does elsewhere, with no equipment beyond the two vessels themselves.
Cultural context
This is domestic and everyday, made twice a day in millions of households, and also the signature of a particular kind of restaurant and street stall. The pulling between tumbler and dabara is performed publicly by vendors at some length, which is where the alternative name 'meter coffee' comes from.
Etiquette
Drunk from the dabara rather than the tumbler in many households, because the lipped bowl is cooler to hold.
Vessel and equipment
A two-chamber stainless steel or brass filter with a perforated plate and a pressing disc, plus the dabara-and-tumbler set that is both serving vessel and mixing tool.

How it is made
Water passes down through a grounds bed held by perforated metal.
The filter itself is never heated: boiling water is poured in and gravity does the rest. The milk is heated separately and is added hot, which is why the drink arrives hot despite a twenty-minute unheated drip.
- Put the coffee-and-chicory grounds into the upper chamber and level them, then set the pressing disc on top and press gently.
- Pour just-boiled water into the upper chamber, cover, and leave it to drip undisturbed. (about 15 minutes)
- Heat milk separately — traditionally full-fat, brought to the boil rather than merely warmed.
- Combine decoction, hot milk and sugar in the tumbler, in roughly one part decoction to three or four parts milk.
- Pour back and forth between tumbler and dabara from an increasing height, repeatedly, until the mixture is evenly blended, cooled to drinking temperature and topped with foam. (about 45 seconds)
- Serve in the dabara-and-tumbler set, foam intact.
- Sugar
- Added at the mixing stage, before pulling, so it dissolves in the process.
- Milk
- Central rather than optional. Hot full-fat milk, boiled, at roughly three to four times the volume of the decoction. This is a milk drink built on a coffee concentrate, not black coffee with milk added.
- Additions
- Roasted chicory in the grounds, typically 10-30 per cent of the blend
- Foam
- The foam comes entirely from aeration during the pull — no steam, no whisk. It is the visible sign the drink was made properly.
- Pouring
- The defining action: repeated pouring between two vessels held progressively further apart, which mixes, cools and aerates in one movement.
How it is served
In the dabara and tumbler together, so the drinker can keep pulling it themselves.
Served with: Idli, dosa and other breakfast dishes
When: Morning and late afternoon, as a fixed part of the day.

What the method does
A long, slow, unagitated drip through a deep bed produces a very concentrated decoction with little fine sediment, since the perforated plate and the packed bed together do the filtering. Diluting that with three or four times its volume of hot milk gives a drink that is strong in flavour but not thin, and the aeration adds a texture that stirring cannot.
What the tradition does
Chicory adds body, a dark colour and a characteristic bitterness. Roasts are usually dark. Full-fat boiled milk contributes sweetness and mouthfeel of its own.
What the method does not control
Indian arabica and robusta blends are the norm and taste unlike the washed African and Central American coffees a specialty drinker may expect. The chicory proportion moves the result more than the origin does.
- Texture
- Silky, with a fine short-lived foam on top.
- Aroma
- Roasted, malty, with chicory's distinctive slightly burnt-sweet note.
- Aftertaste
- Sweet and lingering, with chicory's particular dry bitterness arriving last — regular drinkers identify a cup made without chicory by the finish before anything else.
Caffeine
Moderate and hard to pin down, because the decoction is what carries the caffeine and it is diluted heavily. A 150 ml cup contains perhaps a third to a quarter of its volume as decoction. Chicory contains no caffeine at all, so a 70:30 blend delivers 30 per cent less coffee per spoonful than the same weight of pure coffee — a variable most caffeine comparisons ignore entirely.
CoffeeHQ states no milligram figure for this preparation, because no measurement specific to it has been established. Inventing one would be easy and wrong.
What moves the number
- Chicory proportion, which directly reduces coffee per gram of grounds
- Decoction-to-milk ratio
- Whether the blend contains robusta, which is common in India and roughly doubles caffeine per gram
- Whether the cup is made from first or second decoction
No verified per-serving measurement. The chicory point is arithmetic rather than an estimate, and is the most useful thing CoffeeHQ can say here.
How it differs from
- Vietnamese phin coffee
- Two slow metal drips ending in sweetened milk, and genuinely alike — but the phin brews directly into the serving glass over condensed milk in a few minutes, while the Indian filter produces a batch of decoction in advance that is then mixed with hot fresh milk and aerated. One is a single-serve brewer, the other a concentrate maker.
- Latte
- Both are concentrate plus hot milk. The concentrate here is made by gravity over fifteen minutes rather than by pressure in thirty seconds, and the foam is created by pouring rather than by steam — so the texture is lighter and shorter-lived than steamed microfoam.
In practice
Common mistakes
- Pressing the grounds too hard, which stalls the drip completely
- Using a fine espresso grind
- Adding cold milk, which makes the drink lukewarm and kills the foam
- Skipping the pulling and simply stirring, which produces a related but noticeably flatter drink
Household and regional variation
Chicory proportion is the most argued-over variable; decoction strength, milk quantity and sugar all vary by household and by region. Two regional variations are named often enough to record. In Karnataka and particularly the Malnad coffee-growing districts, jaggery replaces refined sugar — bellada kaapi — and is sometimes dissolved in the water before it goes through the filter rather than stirred in afterwards, which makes the sweetener an extraction variable in the way panela is in Colombian tinto. Cardamom-scented versions are associated with Mysore. Neither is a separate preparation and both are recorded here rather than given pages of their own.
Modern adaptations
Instant decoction concentrates and pre-ground filter blends are widely sold. Some cafés serve the drink in conventional cups, which loses the tool that made it.
Misconceptions
- That chicory is a cheap adulterant. In this tradition it is a deliberate and expected ingredient.
- That 'degree coffee' means a grade of quality. The origin of the term is genuinely uncertain — explanations include the first-run decoction and a lactometer reading used to check milk purity — and CoffeeHQ does not pick one.
- That the pulling is showmanship. It cools, mixes and aerates; a stirred version is a different drink.
- That this is what Indian coffee means. It is what coffee means across Tamil Nadu, Karnataka, Kerala and the Telugu-speaking states; most of India drinks tea, and the country's other coffee story is an institution rather than a method — see the Indian Coffee House.

Evidence
What CoffeeHQ could not establish
- The etymology of 'degree coffee' is genuinely contested and is left unresolved rather than decided.
- Chicory proportions are reported as household conventions rather than measured practice.
- No caffeine measurement, and the chicory dilution makes generic coffee figures inapplicable.
- Whether bellada kaapi's jaggery is normally dissolved in the brewing water or added to the finished cup is described both ways across the recipe sources located, and the difference is mechanically significant. Mega Sprint 43 could not resolve it.
- Indian coffee preparation outside the four southern states is genuinely undocumented in anything CoffeeHQ located, rather than absent. That remains the atlas's largest single geographical gap.
