The Indian Curd Aisle in 2026
Walk into any Indian supermarket in 2026 and the dairy aisle tells a clear story: curd has gone from a single homemade staple to a category with multiple branded options, each positioned differently.
Amul Masti Dahi is the market leader. You will find it in every Dmart, Reliance Fresh, and local kirana store. It is consistent, affordable, and the default choice when you forgot to set dahi at home. Mother Dairy Classic Dahi is the Delhi-NCR favourite — similar positioning, similar pricing, widely available in North India.
Then there is Epigamia, which positions itself as “Greek yogurt” — thicker, higher protein, often flavoured with fruit or honey. It is a different product targeting a different consumer (health-conscious, urban, willing to pay 2–3x more). Several regional brands — Chitale (Maharashtra), Nandini (Karnataka), Verka (Punjab) — serve their respective state markets with similar quality to Amul and Mother Dairy.
And then there is homemade curd — the original, the default, the one that most Indian families still make at home. No packaging, no branding, no supply chain. Just milk, starter, and time.
The question most people ask is straightforward: is there actually a meaningful difference between homemade curd vs store bought, or is it just nostalgia?
The answer is yes, there are real differences — and they matter more than you might think.

Reading the table
Homemade curd dominates on price, probiotics, freshness, and zero additives. Store-bought dominates on convenience and shelf life. Neither is universally “better” — it depends on what matters most to you on a given day.
Why Homemade Wins on Probiotics
This is the section that matters for anyone who eats curd for gut health, digestion, or immunity — and that should be everyone, because probiotics are one of the main reasons curd is considered essential in Indian diets.
Here is what happens inside a container of setting curd:
- Inoculation (0–1 hours): The starter bacteria (Lactobacillus bulgaricus and Streptococcus thermophilus) begin to multiply in the warm, lactose-rich environment
- Exponential growth (1–4 hours): At 42–45°C, the bacteria double every 20–30 minutes. The population grows from millions to billions. They consume lactose and produce lactic acid, which lowers the pH and causes milk proteins to coagulate
- Peak (4–6 hours): Bacterial population peaks. The curd sets as the protein network solidifies. The live culture count is at its highest
- Plateau (6–8 hours): Fermentation slows as the environment becomes more acidic. The curd is now firm and ready to refrigerate
When you eat homemade curd within 24–48 hours of setting, you are consuming bacteria at or near their peak count. A 2019 study published in the Journal of Dairy Science found that freshly fermented curd contains 108 to 109 CFU (colony-forming units) per gram — that is hundreds of millions to billions of live bacteria per spoonful.
What happens to store-bought curd?
Store-bought curd is also made with the same bacteria. But between manufacturing and your kitchen, it goes through:
- Cold storage at the factory (hours to days)
- Refrigerated transport to distribution centres
- Cold chain to retail stores (which is often imperfect in India)
- Shelf time at the store (3–7 days is typical)
- Time in your fridge before you consume it
At each stage, the live bacterial count decreases. Cold temperatures do not kill the bacteria, but they slow their metabolism significantly, and some die over time. Research suggests that by the time store-bought dahi reaches the consumer, the live culture count may have dropped by 1–2 log units (that is 10x to 100x fewer bacteria than at the time of manufacturing).
This does not mean store-bought dahi has zero probiotics. It still contains live cultures — FSSAI mandates this for products labelled as “dahi.” But the count is meaningfully lower than what you get from curd you made 8 hours ago.
When Store-Bought Makes Sense
It would be dishonest to pretend that homemade curd is always the right answer. There are legitimate situations where store-bought is the practical, sensible choice:
- Travelling or staying away from home: You cannot make curd in a hotel room. A cup of Amul dahi from the nearest store solves the problem
- Your batch failed: The milk was too hot, the starter was old, the weather was too cold. It happens. Running to the store is the obvious fix
- No time to plan ahead: Making curd requires 6–8 hours of lead time. If you forgot to set it last night and need it for lunch, store-bought is your only option
- Living alone or in a PG/hostel: If you consume small quantities and do not have the rhythm of daily curd-making, buying a 200g cup when needed is more practical than wasting unused homemade batches
- Guests arriving unexpectedly: You need 2 litres of dahi for raita and you only have 500ml set. Store-bought fills the gap
The point is this: homemade curd vs store bought is not an either-or decision for most families. It is a daily default (homemade) with an occasional backup (store-bought). The best approach is to have a reliable homemade routine and use store-bought when life gets in the way.
| Situation | Best Option | Why |
|---|---|---|
| Daily household consumption | Homemade | Cheapest, freshest, most probiotic-rich |
| Winter months when curd fails | Homemade with curd maker | Consistent temperature solves the seasonal problem |
| Travelling or away from home | Store-bought (Amul / Mother Dairy) | Only practical option |
| Forgot to set curd, need it for a meal | Store-bought | No 6–8 hour lead time available |
| Small quantity, infrequent use | Store-bought (200g cups) | Less waste than making a full litre |
| Greek yogurt or flavoured yogurt craving | Epigamia or similar brand | Different product category; not standard dahi |
How to Make Homemade Effortless
If homemade curd wins on cost, freshness, and probiotics, the obvious question is: why does anyone buy store-bought at all? The answer is consistency. Or rather, the lack of it.
Making curd at home requires you to predict the overnight temperature, choose the right insulation method, and hope that nothing goes wrong in 8 hours. In summer, this is effortless — the ambient heat does the work. In winter, it becomes a gamble.
This is the specific problem an automatic curd maker solves. Here is the process:
- Boil your milk and cool it to lukewarm (42–45°C)
- Add 1–2 tablespoons of fresh starter curd
- Pour into the curd maker container, close the lid, press the button
- Come back in 6–8 hours to perfectly set dahi
The machine does not do anything to the milk. It does not add cultures or speed up fermentation. It simply holds 42–45°C for the duration — replacing the blanket, the oven trick, and the anxiety.
At Rs 1,199, the InstaCuppa Automatic Curd Maker costs less than buying Amul Dahi for 3 weeks (at 1 litre per day). After that, every batch is homemade-priced — Rs 50–60 per litre instead of Rs 75–80.
Monthly cost comparison: homemade vs store-bought (1L/day)
| Item | Homemade (with curd maker) | Store-Bought (Amul) |
|---|---|---|
| Milk / dahi cost per month | Rs 1,500–1,800 | Rs 2,250–2,400 |
| Electricity cost per month | Rs 50–60 | — |
| Curd maker (one-time, amortised) | Rs 1,199 (pays back in ~15 days) | — |
| Monthly saving | Rs 400–900 per month | |

Frequently Asked Questions
Is homemade curd healthier than Amul Dahi?
Nutritionally, both provide similar protein, calcium, and fat content (assuming the same milk fat percentage). The key difference is probiotic count: freshly made homemade curd has significantly more live bacteria than store-bought dahi that has spent days in the cold chain. Homemade curd also has zero additives or stabilisers. For everyday gut health, homemade has the edge.
Why does store-bought curd last longer than homemade?
Commercial curd is manufactured under controlled conditions and sealed in airtight packaging immediately. Some brands use mild pasteurisation after fermentation or add stabilisers that slow further bacterial activity. This extends shelf life to 7–14 days (or longer for products like Epigamia). Homemade curd, made in an open kitchen environment without preservatives, has a natural shelf life of 5–7 days when refrigerated.
Can I use store-bought Amul Dahi as a starter for homemade curd?
Yes, absolutely. In fact, using a fresh cup of Amul Masti Dahi or Mother Dairy Dahi as starter is one of the best ways to reset a weakening home culture. Use 1–2 tablespoons per litre of lukewarm milk. The live bacteria in store-bought dahi are the same species used in traditional curd-making. After 2–3 successful batches, your home culture will be robust again.
Is Epigamia Greek Yogurt the same as dahi?
No. Greek yogurt is strained yogurt — regular yogurt with the whey (liquid) drained out, resulting in a thicker, higher-protein product. Epigamia and similar brands also add flavours, sweeteners, and thickeners. Traditional Indian dahi is unstrained, unflavoured, and made with just milk and starter. They are different products serving different purposes. Dahi is a daily staple; Greek yogurt is more of a snack or dessert.
How much money do I save by making curd at home instead of buying it?
For a family consuming 1 litre of curd daily, homemade costs Rs 50–60 per litre (milk cost; starter comes from the previous batch). Amul Dahi costs Rs 75–80 per litre. That is a saving of Rs 20–30 per day, or Rs 600–900 per month. Over a year, that is Rs 7,000–10,000 saved — plus you get fresher, more probiotic-rich curd.
