The Deg Bhapka Attar Process, Explained Step by Step

The traditional Indian method puts a copper receiver full of sandalwood oil where a condenser would normally go. Here is how it works, and why the numbers you read online do not agree with each other.

Oct 3, 2026

The deg bhapka attar process is the traditional Indian method for capturing a flower's scent directly into sandalwood oil. No alcohol touches it at any stage. The apparatus is copper, bamboo and clay, and the basic design has not changed much in centuries.

Most pages describing it read like tourism copy. They list the vessels, call the craft ancient, and stop. Very few explain the one thing that makes the method different from ordinary distillation, and almost none admit that the published numbers for charge weights and run times contradict each other across sources.

This post covers the vessels and what each does, the step sequence, where the figures disagree and why that matters, and what the method actually changes about the oil in the bottle.

What Makes the Deg Bhapka Method Different

In steam distillation, vapour passes through a cooled coil and condenses into a neat essential oil, which is separated from the water afterwards. The deg bhapka method removes that step. The receiving vessel is not empty. It is already full of sandalwood oil.

Vapour travels from the still into that oil and condenses inside it. The aromatic molecules dissolve into the sandalwood as they arrive. You never get a neat floral oil at any point, because the product is a solution from the first drop. This is why a true attar is an oil in an oil rather than a concentrate diluted later.

The named parts, as the trade uses them:

Deg: the copper still, charged with botanical material and water, sealed at the lid with a clay and cotton paste.
Bhapka: the copper receiver, partly filled with sandalwood oil, which collects and dissolves the condensing vapour.
Chonga: the bamboo pipe linking the two, serving as the vapour path.
Gachchi: the water tank the bhapka sits in, which cools the receiver so condensation keeps happening.
Bhatti: the wood or dung fired furnace under the deg, controlled by eye rather than by gauge.
Kuppi: a leather vessel used for settling, described in trade accounts as drawing residual water out through the skin so it evaporates.

How a Run Actually Proceeds

Charging and sealing

Flowers are picked early, usually before the sun is up, because volatile content falls as the day warms. Petals go into the deg with water. The lid is luted shut with clay and cotton, because a copper still under pressure will leak at the seam, and a leaked run is a lost run.

The exchange

Heat comes up slowly on the bhatti. Vapour crosses the chonga into the bhapka and condenses into the sandalwood. The distiller changes the water in the gachchi as it warms, since a hot receiver stops condensing. Receivers get swapped out and fresh ones fitted while the still keeps running.

Separation and settling

Water collects under the oil in the bhapka and is drawn off, then often returned to the deg for a further pass. The oil goes into the kuppi to settle and shed the last of its moisture. Ageing follows, and the range cited on Wikipedia's attar entry runs from one to ten years depending on the material. If you want the vocabulary around all this, our guide to concentrated perfume oil and attar sorts out which trade words are defined and which are not.

Where the Published Figures Disagree

Detail	One published account	Another published account
Botanical charge in the deg	10 to 160 kg	roughly 45 kg
Sandalwood oil in the bhapka	5 to 10 kg	roughly 5 kg
Run length	several hours to a few days	8 to 10 hours daily over 10 to 20 days
Ageing	not stated	one to ten years

These are not small gaps. A charge range of 10 to 160 kg and a run described as either hours or three weeks cannot both be the general case, and the longer figures come from a single trade account we could not corroborate. Treat any confident single number you read as one distillery's practice, not an industry standard.

What This Means in Toronto

We buy finished oils, not flowers. That means the question we can actually answer for you is which distillery a batch came from, what the base is, and when it was distilled. We ask it, and we will tell you the answer plainly, including when the answer is that a supplier would not say.

Bottling happens here, by hand, in small runs across the GTA. A deg bhapka oil behaves predictably in Toronto air. It has almost no top note lift, so in February cold it will sit close and open slowly against warm skin. In August humidity the same oil reads heavier and carries further. Nothing flashes off in the first ten minutes the way an alcohol spray does, which is the main thing GTA buyers notice when they switch.

Frequently Asked Questions

Is all attar made by the deg bhapka process?

No. A large share of oil sold as attar today is made by blending aroma materials into a carrier without any distillation. The method is traditional, not universal, and the label rarely tells you which you have.

Does the deg bhapka process use alcohol?

No. Water, heat, botanical material and a sandalwood base are the only inputs. The absence of alcohol is a property of the method itself, not an additive choice made afterwards.

Why sandalwood as the receiving base?

It is a stable, low odour fixative that holds volatile molecules well and ages without turning. Sandalwood supply pressure has pushed some distillers toward liquid paraffin or other bases instead.

Is deg bhapka the same as hydrodistillation?

It is one form of it. The distinguishing feature is the charged receiver, which makes the product a solution rather than a neat oil separated after the fact.

Where is this still practised?

Kannauj in Uttar Pradesh is the centre most often named in published accounts, though the method is not confined to one town.

Does a deg bhapka attar smell stronger?

Not stronger, closer. The oil warms on skin and projects modestly, which reads as quieter than a spray even when it lasts considerably longer.

Where We Stand

Oud Toronto bottles alcohol-free attar by hand in Toronto and delivers it across the GTA. We are interested in the deg bhapka attar process because it explains why a traditional oil behaves the way it does on skin, not because tradition is a selling point on its own. When we cannot verify how a batch was made, we say so rather than borrowing the romance of a method we did not use.
