The label on a jar of A2 bilona ghee tells you almost nothing on its own. What separates a genuine one from an expensive one is verifiable: the milk-to-ghee yield ratio, a batch-coded lab report, the FSSAI licence number, and whether the brand will tell you which animals the milk came from and what they ate. Six checks cover all of it, and most take a minute.
A2 bilona ghee has become one of the most crowded premium categories in Indian groceries. Prices vary several-fold, and almost every jar on the shelf carries the same four words. The words are not regulated in any way that separates one producer from another, so they have stopped carrying information. What follows is the checklist we would use ourselves. Most of it applies to any brand, not only to ours.
At a glance
- Ask for the yield ratio: curd-churned (bilona) cow ghee needs about 30 litres of milk per litre; cream-separated ghee needs 20 to 23.
- Ask for a lab report that carries the batch code printed on your jar, from an NABL-accredited laboratory, not a single certificate reused for every batch.
- The lines that matter on that report are moisture, free fatty acids, the Baudouin test for vanaspati, the Reichert-Meissl value and the butyro-refractometer reading, the identity tests in FSSAI's ghee standard.
- "A2" describes a milk protein that clarification removes; it is a clue to the breed, not a quality of the ghee.
- Check the 14-digit FSSAI licence number on the label, prefer glass, and be suspicious of any bilona claim the price cannot support.
What does "bilona" actually commit a producer to?
A sequence, not a flavour. Whole milk is set into curd overnight with a starter culture; the curd is churned, traditionally on a wooden bilona, until butter separates; and that butter is simmered until the water cooks off and the milk solids brown. The shortcut that most industrial ghee takes skips the curd: cream is separated mechanically and clarified directly.
The two routes differ in time, in aroma and, most usefully for a buyer, in one number that is hard to disguise:
| Method | Milk per litre of ghee | What drives the aroma |
|---|---|---|
| Curd-churned (bilona) | About 30 litres | Fermentation plus browned solids |
| Cream-separated | About 20 to 23 litres (cow milk) | Browned solids only |
| Butter-melted (bulk) | Varies; often blended | Little; frequently flat |
The gap looks modest, but it compounds: curd-churning needs roughly a third more milk for the same jar, usually milk bought in the hills at above the bulk dairy rate, plus overnight culturing and hand churning. That cost has to appear in the price. If a ghee is described as bilona and is priced near commodity ghee, one of those two claims is doing something it should not be. The full comparison is in bilona ghee vs cream ghee.
Does the A2 part matter as much as the bilona part?
No, and this is where most category marketing overreaches. A1 and A2 are two variants of beta-casein, a milk protein, differing by one amino acid. The distinction is real in milk. In ghee it largely washes out, because ghee is at least 99.5 per cent milk fat and beta-casein leaves with the milk solids during clarification.
Most European-origin breeds carry A1; most indigenous Indian breeds, including Badri, Gir and Sahiwal, carry A2. So the label is a reasonable clue that the milk came from indigenous animals, which in India usually means grazed rather than stall-fed animals. That is worth knowing, but it is a sourcing signal, not a nutritional one.
What survives clarification is the fat, and fat composition tracks diet closely. An animal grazing wild herbs at altitude produces measurably different fat from one on compound feed: more carotene, a different fatty acid profile, a different aroma. That is the difference worth paying for, and it is a question about the herd, not about genetics. We go through the evidence in A1 vs A2 ghee, and through what the breed does and does not change in Badri cow ghee explained.
Which six things should you check before buying?
The yield ratio, a batch-coded report, what that report tests, the FSSAI licence, the sourcing specifics and the jar. The first two do most of the work, because a brand that can answer them has usually got the rest right as well. A brand that cannot is asking you to trust the label.
- The yield ratio. Ask how many litres of milk go into a litre of ghee. A bilona producer should answer without hesitating, and the answer should be in the high twenties or above.
- A batch-coded lab report. Not a generic certificate: a report you can match to a code printed on the jar you are holding. A brand that tests once a year and publishes one PDF is telling you about a batch you will never receive.
- What the report tests. The lines that establish identity and purity are moisture, free fatty acids, the Baudouin test for vanaspati, the Reichert-Meissl value and the butyro-refractometer reading. A report showing only fat content is a report designed to pass. Contaminant tests (heavy metals, pesticide residues, aflatoxin M1) are a separate, additional request; a batch report that covers composition and purity is the norm, and ours is one of those: it does not include heavy-metal, pesticide or aflatoxin results.
- The FSSAI licence number. It is printed on every legal food label in India and can be checked on the FSSAI site. Ours is 22626041000050.
- Sourcing specifics. Breed, region, altitude, and whether the animals graze or are stalled. Vague geography, "the Himalayas", usually means pooled milk.
- The jar. Glass over plastic. Ghee is a fat, and fats pick up plasticisers and off-flavours over a long shelf life.
What does good ghee look and smell like?
Granular rather than smooth, gold rather than uniform, nutty rather than flat. Genuine curd-churned ghee sets unevenly, with the slightly crystalline grain the trade calls danedar; its colour follows the season, deeper when animals are on green forage and paler in winter. Melted, it runs clear with no sediment, and it smells nutty and faintly caramelised.
Sensory checks will not replace a lab report, but they catch the obvious problems. A flat or waxy smell, or a texture that stays perfectly smooth in every season, points to cream-based or blended production, and a ghee that is exactly the same shade all year is worth a question. The grain itself is not proof of purity, since it depends on how the ghee was cooled, and what makes ghee danedar explains why. The home tests worth running, and the ones that do not work, are in how to tell if ghee is pure.
How much should A2 bilona ghee cost?
Work back from the milk. At about 30 litres per litre, and hill milk bought at a fair rate to the farmer, the raw material alone sets a floor well above commodity ghee. Glass, per-batch testing and slow small-batch production come on top. Cheaper than that with the same claims means cream-separated production, pooled milk or blending; far dearer is not automatically better.
Past the point where the price covers milk, labour, testing and glass, you are paying for packaging and marketing rather than for ghee. The arithmetic, with an illustrative milk rate, is in how to judge a fair A2 ghee price. You can see how we price against that logic on the ghee itself, and the reports behind each batch are on our lab reports page.
Who should not bother with premium ghee?
Anyone whose ghee mostly goes into deep frying. Prolonged high heat drives off the aroma compounds and destroys the carotene you are paying for, and commodity ghee performs the same job for a fraction of the cost. Premium ghee earns its price where you taste it: finishing dal, finishing rice, on roti, in halwa, in anything where it goes in near the end.
That is a narrower use case than the category's marketing implies, and it is worth being clear about before paying a premium for a litre. Many households keep a commodity ghee for the pan and a small jar of good ghee for the table, and use less of the good one than they expect.
What do the numbers on a ghee lab report mean?
A certificate of analysis is only useful if you can read it. Five lines carry most of the information: moisture and free fatty acids tell you how the ghee was finished and handled, and the Baudouin test, Reichert-Meissl value and butyro-refractometer reading tell you whether it is pure milk fat. FSSAI sets limits for each in its standard for ghee.
| Line on the report | What it is measuring | Why it matters |
|---|---|---|
| Moisture | Water left after clarification | Water is what lets ghee spoil. FSSAI allows at most 0.5 per cent; properly finished ghee is nearly dry, which is why it keeps without refrigeration. |
| Free fatty acids (FFA) | Fat that has begun to break down | Rises with age, heat and poor storage. A low figure indicates fresh, carefully handled ghee. |
| Baudouin test | Presence of vanaspati or sesame-oil-marked vegetable fat | The standard screen for the most common adulteration in Indian ghee. FSSAI requires it to be negative. |
| Reichert-Meissl value | Short-chain volatile fatty acids | Characteristic of genuine milk fat. Vegetable fats do not produce comparable figures, so a low value suggests dilution. |
| Butyro-refractometer reading | How the fat bends light at 40 °C | Another compositional fingerprint of milk fat, and another way blending shows up. |
| Heavy metals, pesticide residues, aflatoxin M1 | Contaminants from the environment, equipment or feed | Not part of the identity standard and not on most batch reports, including ours. Ask whether a brand tests for them separately. |
FSSAI's limits are the floor, not a mark of quality: clearing a legal minimum is not the same as being good. What distinguishes a serious producer is testing every batch against those lines and publishing the result, rather than testing once and reusing the certificate. Ask whether the report is from an NABL-accredited laboratory, because accreditation is what makes the number on the page mean something outside the building it was produced in. We go line by line through a real report in how to read a ghee lab report.
The short version
Ask for the yield ratio and a batch-coded report from an accredited laboratory. Read the moisture, free fatty acid and Baudouin lines on it. Treat "A2" as a sourcing signal rather than a nutritional one, and ask instead what the animals ate. Prefer glass, check the FSSAI number, and be suspicious of any bilona claim that is not reflected in the price, because the arithmetic of curd-churning does not leave room for a bargain.
