The Bilona Method: How A2 Gir Cow Ghee Is Actually Made
Bilona ghee is made by culturing whole milk into curd overnight, hand-churning that curd into butter, and simmering the butter slowly until the water cooks off and ghee remains. It is the older of the two ways to make ghee, and the slower one. Between 25 and 30 litres of milk go into a single litre.
Almost all ghee sold in shops is made a different way: cream is separated from milk by centrifuge and cooked directly into ghee, skipping the curd and the churn entirely. Both products are legally ghee. They are not the same thing, and this page explains exactly where they part company.
What is the bilona method?
Bilona takes its name from the wooden churner used to work the curd. The full process has four stages, and none of them can be hurried:
- The milk is set into curd. Whole milk is cooled to about body temperature, cultured, and left overnight to set. This fermentation step is the one the industrial method leaves out, and it is where much of the aroma comes from.
- The curd is churned. The set curd is churned — traditionally by hand with a wooden bilona — until butter separates and floats. What is left behind is buttermilk, not skimmed milk.
- The butter is washed and simmered. The butter is rinsed, then cooked over a low flame. Water steams off, milk solids settle and brown, and the fat clarifies.
- It is strained and jarred while warm. The browned solids are strained out and the ghee is poured warm, then left to set at its own pace.
How much milk does one litre of ghee take?
Between 25 and 30 litres. That single ratio explains most of the price difference between hand-churned and factory ghee. Cream separation extracts far more fat per litre of milk, faster, with less labour and no overnight wait. Bilona spends milk to buy character.
Bilona versus machine-made ghee
| Bilona (hand-churned) | Industrial (cream-separated) | |
|---|---|---|
| Starts from | Curd, set overnight | Cream, separated by centrifuge |
| Fermentation step | Yes — this is the difference | No |
| Milk per litre of ghee | 25–30 litres | Considerably less |
| Texture when set | Often grainy (danedar) | Usually smooth and uniform |
| Batch size | Small, often made to order | Continuous, stored |
| Time per batch | Roughly a day, most of it waiting | Hours |
Why does real bilona ghee turn grainy?
That granular texture has a name — danedar — and it is normal. It happens when ghee cools slowly enough for the fat to crystallise rather than setting as one smooth block. A grainy jar is generally read as a sign of an unhurried cook. A perfectly uniform one is not evidence of anything wrong; it usually just means the ghee was cooled quickly.
What is the smoke point of ghee?
Ghee smokes at roughly 250°C, well above most cooking oils and far above the temperature of a domestic tadka. Because the milk solids and water have already been cooked out, there is very little left in it to burn — which is why it holds up to frying and to the high heat Indian cooking tends to use.
Why is it more expensive?
Three reasons, in order of weight: the milk-to-ghee ratio above; the labour, because churning and slow-cooking small batches does not scale the way a centrifuge does; and batch size, because ghee made to order is not made in bulk and stored. None of those premiums buy a different chemical product. They buy a different process.
How to store it
Keep the jar closed, cool, and out of direct sunlight, and always use a dry spoon. Moisture is what spoils ghee — not air, and not time. Refrigeration is unnecessary, though it does no harm in a humid summer. Ghee that has been kept dry lasts a long while at room temperature.
Where this ghee comes from
Organic Farmz makes A2 Gir cow ghee this way, in Delhi, in small batches. A2 refers to the beta-casein protein in the milk of indigenous Gir cows, as distinct from the A1 protein in most crossbred dairy milk — it describes the breed and its milk, not a health claim. Every jar is made after the order is placed, and a 1 litre jar is Rs 2,400.
