Cow ghee and buffalo ghee differ in colour, hardness, aroma, yield and price, not in whether they are real ghee. Cow ghee is yellow from carotenoids, softer, and takes about 30 litres of milk per litre by the bilona method; buffalo ghee is white, distinctly harder, and comes from milk with roughly twice the fat, so it needs far less milk and costs less. Both must meet the same FSSAI standard.
India makes more ghee from buffalo milk than from cow milk, yet cow ghee commands the premium. Some of the reasons are real and measurable; some are marketing. This article sets the two side by side on what laboratories have actually measured: colour, fatty acids, identity values and yield, then on what that means in the kitchen.
At a glance
- Milk: FSSAI's minimum fat is 5 per cent for buffalo milk and 3.2 per cent for cow milk; the buffalo milk in a 2022 Bangladesh study measured 7.5 per cent.
- Colour: in a 2022 NDRI study, cow ghee's yellowness index ran 74 to 89 and buffalo ghee's 5 to 22; buffalo ghee's whiteness index ran 69 to 85 against cow ghee's 16 to 29.
- Fat: NDDB reports that buffalo ghee carries more butyric acid and more high-melting triglycerides, which is why it is harder, and that cow ghee has nearly 5 per cent less saturated fat.
- Identity tests: buffalo ghee gave Reichert-Meissl values of 31.9 to 40.0 against cow ghee's 27.5 to 31.1, and higher Kirschner values; the two can be told apart in a lab.
- Both are at least 99.5 per cent milk fat under FSSAI's standard, and neither has been shown healthier in a human study.
Why is cow ghee yellow while buffalo ghee is white?
Because of what each animal passes into its milk fat. Cows transfer carotenoids from green feed into their milk, and the ghee comes out yellow, deeper after the monsoon and paler in winter. Buffaloes do not; the National Dairy Development Board's ghee bulletin notes that buffalo ghee lacks carotenoids and instead contains biliverdin and bilirubin, which give it a faint greenish tint.
The difference has been measured. A 2022 study from the National Dairy Research Institute in Karnal, published in the Journal of Food Science and Technology, made pure cow and buffalo ghee by the creamery butter method and measured their colour. Cow ghee's yellowness index ranged from 74.25 to 88.92 and buffalo ghee's from 5.21 to 22.46; the whiteness index ran the other way, 16.07 to 28.85 for cow ghee and 68.74 to 84.61 for buffalo. The authors found that the whiteness index still shifted measurably when 20 per cent buffalo ghee was mixed into cow ghee, which makes it one of two values that can catch that blend. Why cow ghee's own colour moves through the year is covered in why ghee is yellow or white.
How does the milk's fat content change yield and price?
Buffalo milk carries roughly twice the fat of cow milk, so a litre of ghee needs roughly half as much of it. FSSAI's legal minimum is 5 per cent fat for buffalo milk against 3.2 per cent for cow milk, and the buffalo milk in a 2022 Bangladesh study measured 7.5 per cent. Milk is the largest cost in any ghee, which is the whole reason buffalo ghee is cheaper.
The arithmetic: a litre of ghee holds a little over 900 grams of fat. Cow milk at about 4 per cent fat gives 40 grams a litre, so even perfect recovery needs more than 20 litres, and curd-churning, which the NDDB bulletin says recovers only 80 to 85 per cent of the fat, pushes the figure to about 30 litres. Buffalo milk at 7 per cent gives 70 grams a litre: about 13 litres at perfect recovery and roughly 15 to 16 by the same method. Why bilona ghee needs about 30 litres of milk works through the cow figures in detail.
At Himdhara, whole milk from free-grazing Badri cattle in the Uttarakhand hills is set into curd and churned on wooden bilonas, taking about 30 litres of milk for every litre of ghee. That ratio, and the higher price of hill milk, is why cow ghee made this way costs what it does; how to judge a fair A2 ghee price explains the rest of the cost stack.
Is the fat itself different?
Slightly, and in ways you can feel. The NDDB bulletin, citing earlier Indian dairy research, reports that buffalo ghee carries more butyric acid (6.7 against 3.6 grams per 100 grams of fatty acids) and a much higher share of high-melting triglycerides (8.7 against 4.9 grams per 100 grams), because it has more of the long-chain saturated fatty acids palmitic and stearic. That is why buffalo ghee is distinctly harder.
The same bulletin notes that cow ghee contains nearly 5 per cent less saturated fat than buffalo ghee, and that buffalo ghee's higher share of unsaturated glycerides makes it a little more prone to oxidation in storage. A 2022 analysis of buffalo ghee in the Journal of Advanced Veterinary and Animal Research found its major fatty acids were butyric, myristic, palmitic, stearic and oleic acids, the same set that dominates cow ghee, with a saponification value of 225 and a Reichert-Meissl value of 30. The short-chain fatty acid that makes buffalo ghee's RM value higher is butyric acid.
Can a laboratory tell the two apart?
Yes, on two values. The NDRI study measured the identity tests used in India's ghee standard on both kinds. Butyro-refractometer readings overlapped (41.87 to 43.62 for cow, 40.01 to 43.23 for buffalo), but the Reichert-Meissl value, which reflects short-chain fatty acids, and the Kirschner value, which reflects butyric acid specifically, both ran higher in buffalo ghee.
| Measurement (NDRI, 2022) | Pure cow ghee | Pure buffalo ghee |
|---|---|---|
| Butyro-refractometer reading at 40 °C | 41.87 to 43.62 | 40.01 to 43.23 |
| Reichert-Meissl value | 27.5 to 31.13 | 31.91 to 39.99 |
| Polenske value | 1.30 to 1.90 | 1.10 to 1.50 |
| Kirschner value | 20.74 to 24.14 | 26.84 to 33.96 |
| Yellowness index | 74.25 to 88.92 | 5.21 to 22.46 |
| Whiteness index | 16.07 to 28.85 | 68.74 to 84.61 |
When the researchers mixed 5 to 20 per cent buffalo ghee into cow ghee, most values stayed inside the range of pure cow ghee samples, but the Kirschner value and the whiteness index rose significantly, so those two are the ones a laboratory uses to catch the blend. What each line on a ghee report means is explained in how to read a ghee lab report.
How do cow ghee and buffalo ghee compare nutritionally?
Almost identically. Both are at least 99.5 per cent milk fat under FSSAI's standard, so a spoon of either is a spoon of fat: USDA's record for clarified butter lists 900 kilocalories, 100 grams of fat and 60 grams of saturated fat per 100 grams. The differences the NDDB bulletin reports, a little less saturated fat and some carotene in cow ghee, are real but small per serving.
Claims that cow ghee is medicinal in ways buffalo ghee is not have not been shown in people. A 2016 study in the Journal of Clinical and Diagnostic Research fed cow ghee and butter to Wistar rats for 21 days and tested their memory in two maze models: neither fat had a significant effect on memory, and both raised triglycerides and VLDL in at least one model, though the ghee group gained less weight than the butter group. That is an animal study, not evidence about people. ICMR-NIN's Dietary Guidelines for Indians count ghee of any kind inside the daily allowance for visible fat and advise limiting ghee and butter; how much ghee per day sets out the guideline figures. If you have a heart condition, high cholesterol or another medical reason to watch fats, follow your doctor's advice.
Which ghee should you choose for cooking and daily use?
By job. Buffalo ghee is harder, paler and milder, which is why sweet-makers often prefer it for barfi and laddoo that must set firm and keep their colour. Cow ghee is softer, more golden and more aromatic, and suits finishing, a spoon over dal, rice or a hot roti, where you taste it directly. For high-heat frying, either works, and the cheaper one is the sensible choice.
| Property | Cow ghee | Buffalo ghee |
|---|---|---|
| Milk fat, FSSAI minimum for the milk | 3.2 per cent | 5 per cent (often 7 or more in practice) |
| Milk per litre of ghee, curd-churned | About 30 litres | Roughly half, by the fat arithmetic |
| Colour | Golden yellow, from carotenoids | White with a greenish tint, from biliverdin and bilirubin |
| Hardness at room temperature | Softer, often grainy | Distinctly harder (more high-melting triglycerides) |
| Aroma and flavour | Pronounced, nutty | Milder, creamier |
| Reichert-Meissl value (NDRI, 2022) | 27.5 to 31.13 | 31.91 to 39.99 |
| Keeps best | Both: closed, dry, dark, away from heat | Slightly more prone to oxidation, so the same care matters more |
- For finishing and drizzling: cow ghee, if you enjoy a deep, roasted-nut aroma over warm dal, khichdi or rotis.
- For sweets that need to set: buffalo ghee for a firm, pale result, or cow ghee for a golden colour and more aroma.
- For frying in volume: whichever is cheaper, because heat drives off the aroma you would otherwise pay for.
- For your diet: count the fat, not the animal. Both are nearly pure milk fat.
Whichever you buy, store it the same way, closed, dry and out of the light, as how to store ghee explains, and ask for the batch report. Ours, for Himdhara's A2 bilona ghee, are published on the lab reports page before each batch ships.
The short version
Cow ghee is yellow, softer and more aromatic; buffalo ghee is white, harder and milder, because its fat carries more butyric acid and more high-melting triglycerides. Buffalo milk has roughly twice the fat of cow milk, so buffalo ghee needs about half as much milk and costs less. Laboratories tell them apart by the Kirschner value and the whiteness index. Neither has been shown healthier in people, so choose by taste, texture, use and price.
