Punjab grows a great deal of rose, and almost none of it is grown for perfume. That one fact explains most of what is strange about buying rose in Pakistan.
The belt around Pattoki, in Kasur district, is the country's largest concentration of flower nurseries and rose fields, and there are working fields around Chiniot, Faisalabad, Sheikhupura and out towards Lahore. What comes off them goes mostly to garland makers, to the gulqand and rose-water trade, and to shrines. Perfumery is a small customer in a market shaped by weddings and religious festivals, which is why the price of petals can double in a week for reasons that have nothing to do with oil.
It has to be the right rose
The tight, long-stemmed roses grown for cut flowers were bred for colour and for vase life, and most of them smell of very little. The roses that matter for distillation are the Damask types — Rosa damascena and its relatives — and the loose, blowsy local desi gulab. They open flat, they drop their petals early, and they would be a commercial failure in a florist's bucket. They are also where the scent lives.
Four hours, and then the day is over
Picking starts in the dark and stops when the sun clears the treeline. This is not romance, it is chemistry: the volatile oil is at its highest concentration in the cool, humid hours before dawn, and it falls away once the flower warms and the oil begins to evaporate off the petal. Every rose-growing region in the world — Bulgaria, Isparta, Kashan, Kannauj — arrived at the same working day independently, which is about as strong as agricultural evidence gets.
What happens after picking matters just as much and gets far less attention. Petals piled into sacks begin to heat and ferment within hours. A field an hour from the still yields a different material from a field four hours away, same variety, same morning. This is why a small perfumery buys rose by the batch and by nose rather than by specification.
The season is short. The main flush comes in spring, roughly March into May depending on the year and the field, with a lighter second showing in some years. Everything the still will see that year is decided inside a few weeks.
Two processes, two materials
Hydrodistillation gives rose otto — the attar — along with a very large quantity of rose water as a co-product. In Pakistan the rose water is often the commercially serious half of that equation. It goes into food, into gulqand and into ritual use, and the oil is the smaller, far more valuable thing floating on top of it.
Solvent extraction is the other route. It gives a waxy concrete, and then, washed out with alcohol, an absolute. Otto and absolute do not smell the same. Otto is lighter and waxier, honeyed, with a peppery lift. Absolute is deeper and jammier, closer to a bruised petal held in the hand. Neither is better than the other; they do different jobs, and a composition built around one cannot simply be switched to the other.
The traditional method still practised in this region is the deg-bhapka: a copper still and a copper receiver, with the distillate captured directly into a base of sandalwood oil rather than into water. It is slow and it is fuel-hungry, and what it produces is an attar rather than an isolated oil. The sandalwood is part of the finished material, not a diluent stirred in afterwards.
The arithmetic nobody enjoys
The figure quoted across the industry for rose otto is on the order of three to four tonnes of flowers for a single kilogram of oil. Whatever the exact number in a given season, the shape of it does not change: an enormous weight of hand-picked petals, gathered inside a four-hour window, for a very small quantity of material.
That is the whole economics of rose, and it is why rose oil is among the most adulterated materials in the trade. Geranium and palmarosa stretch it convincingly, and a synthetic reconstruction can be built for a fraction of the cost. It is also why most rose water sold on a shelf is water and a fragrance compound, and why the real thing costs what it does.
What this means if you are buying
Local rose can be excellent. It is not standardised, and it should not be sold as though it were. Ask which flush it came from, ask how far the field was from the still, and expect an honest answer to include the word "varies". A batch and a nose are worth more than a grade printed on a label.
It is worth remembering whose hands the material passes through first. Smallholders with small plots, and pickers — mostly women, paid by weight — working the two hours before sunrise so that the oil is still in the flower when it reaches the copper.
