India's household survey counts home-set dahi as milk
NSS field instructions: "suppose a household purchased 30 litres of milk, out of which 15 litres was converted into curd … the entire amount of 30 litres will be shown against 'milk: liquid' only." The survey's curd line therefore measures bought curd alone, which makes the gap to total curd measurable.
Curd consumed in India, by volume
Total curd is 16.8–20.9 Mt a year: curd is ~13% of household dairy consumption (NDDB demand study), or 7% of the 239 Mt milk output by the older utilisation norm. Packaged curd is ₹113.7bn of a ₹758bn curd market (1Lattice, via the Milky Mist offer document), converted at ₹70–100/kg shelf price.
Bought curd is a sliver of the milk that enters the home
| Rural | Urban | |
|---|---|---|
| Liquid milk, L / person / month | 4.33 | 5.42 |
| Bought curd, kg / person / month | 0.024 | 0.062 |
| Bought curd as % of milk | 0.6% | 1.1% |
| Households buying any curd in a month | 6% | 17% |
NSS 68th round, Report 558. Bought curd climbs with income: 0.181 kg in the top urban fractile vs 0.008 kg at the bottom.
Organised curd is compounding
1Lattice figures as reproduced in the Milky Mist DRHP. The South is ~35% of the curd market, the North ~30%. An urban 10-city household study put home-made at "close to 80%" of curd consumption.
Each 1% of the home batch that moves to a bought culture is worth about ₹2bn a year
The home-set pool is the verified number. How much of it converts to a paid starter is the open question, so the sizing is shown as a sensitivity rather than a point estimate.
The pool
| Total curd consumed | 16.8–20.9 Mt / yr |
| Less packaged (~6–11%) | 1.1–1.6 Mt |
| Set at home | ~14–19 Mt / yr |
| Milk behind it, at ~₹55/L | ~₹0.8–1.0 trn |
Loose curd bought from dairies is not separable in any source and sits inside the home-set figure, so the pool is an upper bound.
Culture revenue by share of home volume set with a bought starter
Assumes a ₹25 sachet that sets 2 kg (an illustrative price point) and a 16 Mt midpoint pool. Home-setters restart from the previous batch, so a realistic model is a starter every few weeks, not every batch. A culture used once a month by a daily setter covers roughly 1/15th of their volume.
Buying is a southern and metro habit. Setting belongs to the Hindi belt.

Bought curd, urban, kg per person per month
NSS 68th round. Rural UP, MP, Rajasthan and Haryana: 1–2% of households buy curd in a month.
"curd packet" share of search, paired with "how to make curd"
Google Trends, five-year state index. "Curd delivery" registers only in Karnataka, Tamil Nadu and Telangana.
"dahi kaise jamaye" share, paired with "dahi price"
Hindi-language pairing, so read within Hindi-reading states. Hindi setting videos on YouTube: 57.2M views across the top 11, one at 27.8M.
Karnataka sits on both sides
It is among the heaviest curd-buying states in the survey and in search, and it also leads the country on "curd starter" (index 100) and "how to make curd" (62). A metro cohort moving back to setting fits both signals.

On quick commerce, bought curd is a staple, and Mumbai leads
Curd velocity is inferred from hourly shelf-inventory depletion on Blinkit, across six dark stores in each of twelve cities. The index ranks cities; it does not size them.
| City | Curd sold per store (Mumbai = 100) | 1 kg+ pack share | Plain-curd SKUs / store | Lead brands |
|---|
Single cups under 350 g are 1–14% of curd kilos in every city. Starter cultures are absent from Blinkit, Instamart and Zepto; the only culture listed is a kefir starter.
Home-setters are fighting the batch, and few are shopping for a fix
3,846 Google and YouTube autocomplete suggestions, seeded with setting and buying phrases in English, Hindi and regional languages, grouped by intent.
Autocomplete suggestions by intent
"Bina jaman" (no starter), chilli, lemon and milk-powder hacks outnumber buying a starter about 4 to 1. Packaged-curd queries lean toward safety, preservatives and probiotics more than brand choice.
Failure mentions in comments & reviews
YouTube comments, Reddit threads and Amazon reviews, regex-tagged. Of 69 verbatims that state a behaviour, 53 describe setting at home. All five switches found run toward home.

"Usually what I do is put small amout of curd in the milk, mix it and keep it in the warm place. But the texture and feel of the curd is not same as the purchased one."r/IndianFood

Bull and bear
For
| Mass habit, unmonetised. 85–90% of curd is set at home, with no bought input beyond milk. |
| Failure is frequent and vocal. Runny, sour, winter and not-setting dominate comments, and 623 autocomplete suggestions are about setting without a starter or finding one. |
| Paying for texture already happens. Hung-curd strainers sell ~9.4K a month, curd makers ~2.1K, clay pots ~1.8K. |
| Incumbent product under-delivers. Starter cultures carry a 21.7% 1–2★ share, the worst of any adjacent product; there is no scaled Indian dahi-culture brand. |
| Safety scares push people home. Every switch found in the voice data ran from packaged to home-set, several after a packaged-curd lab-test scare. |
Against
| The substitute is free. Yesterday's bowl sets today's. A bought starter competes with ₹0, not with packaged curd. |
| Buying curd is the growth trend. Organised curd compounds at ~18.6% a year, and the metros most reachable online are already the most buy-heavy. |
| The heaviest setters are the hardest to reach. Home-setting peaks in rural and small-town Hindi-belt households, where search intent is highest but online and quick-commerce reach is thinnest. |
| Demand today is tiny. ~450 starter units a month on Amazon, zero listings on the three quick-commerce platforms. |
| Imports win the premium niche. The best-selling cultures are Greek and Bulgarian, bought for yogurt, not dahi. |
