Ask around and someone will tell you it takes exactly 30 litres of milk to make a kilo of ghee. Someone else will insist it’s 25. Both will sound certain. The milk, unfortunately, hasn’t agreed to either number.

Around 25 to 30 litres is a useful estimate for 1L of desi cow ghee. The actual quantity changes with the fat content of the milk and how much of that fat is recovered while making ghee.

Why isn’t there one fixed number?

Milk isn’t all fat. It also contains water, proteins, lactose and minerals. To make ghee, you separate out the fat and remove almost all the water and non-fat milk solids. Under FSSAI standards, ghee must contain at least 99.5% milk fat.

So a litre of milk with more fat has more of what you need. If two batches of milk have different fat levels, they won’t give you the same amount of ghee, even if you follow the same method.

Here is what that looks like in rough numbers:

For this illustration, assume milk weighs about 1.03L per litre and 85% of its fat makes it into the finished ghee. Those assumptions aren’t a promise that every batch will behave this way. Change the milk or the process and the yield changes too.

Does the bilona method change the amount?

With bilona ghee, milk is made into curd, the curd is churned to separate the butter, and the butter is heated to make ghee. Some fat can remain behind during those steps. How much is recovered affects how much milk you need.

That’s why a maker can’t honestly guarantee that every kilo of desi cow ghee began with precisely the same number of litres.

Does A2 milk make more ghee?

No. A2 describes a form of beta-casein, a protein in milk. It doesn’t describe how much fat the milk contains. So seeing “A2 ghee” on a listing tells you nothing about the litres needed to make a kilo.

If you see “A2 desi cow ghee”, the same point applies: the yield depends on milk fat and processing, not the A2 label.

Should a bigger milk number mean a higher ghee price?

The milk used affects cost, but a large number on its own isn’t a quality certificate. One maker may need more litres because the milk has less fat. Another may need more because less fat is recovered. Neither figure tells you which ghee tastes better. Sourcing, production and handling matter when you’re comparing jars of desi cow ghee.

If a brand says its ghee takes 30 litres of milk per kilo, that’s a useful detail to ask about. Ask whether it’s an average, a figure for that batch, or simply a number printed on every jar. The answer will tell you more than the number alone.

FAQs

How many litres of milk make 1L ghee?
Around 25 to 30 litres can be a practical estimate, depending on the milk's fat content and the method used.

Does 30 litres of milk always make 1L desi ghee?
No. The yield can change depending on the fat content of the milk and the efficiency of the process.

Does A2 milk produce more ghee?
A2 refers to beta-casein, not milk-fat content, so it does not determine ghee yield.

Can 25 litres of milk make 1L ghee?
Yes, depending on the fat content of the milk and how efficiently the fat is recovered.
