Why one composition: a signature only becomes an identity through repetition, and the member who uses two of your properties is the person for whom that repetition does the most work. Two fragrances across a group is not variety; it is the absence of a signature.
Why the setting must be local: four things differ building by building and all four change how much fragrance a room needs. Absorbency — carpet, curtains and upholstery hold and re-release odour where stone and glass do not. Air change — air that leaves takes the fragrance with it, so the same machine behaves oppositely in a leaky heritage building and a sealed new one. Humidity — the same composition reads heavier in a damp coastal room than in a dry conditioned one, without a single molecule changing. Occupancy — a club full every evening and empty by day is a different problem from one that runs all day.
What may also differ: the hardware. A property on one air system may take a single Aangan ₹25,999 at the air handling unit, rated to up to 3,000 m³. A property of the same floor area spread over three floors behind closed doors may need several Vaayu ₹11,999 zones instead, each rated to up to 1000 m³. Same identity, different machines, and that is not an inconsistency.
The honest warning: a group that writes one intensity figure into a group standard has standardised the wrong variable. It will get one property right — usually the one where the figure was first set — and will be told politely by members at the others that the club smells of nothing, or of too much.
The commercial gap: no group pricing, framework agreement, multi-site discount or portfolio terms are published. Each property is specified and quoted on its own through the contact page, and no purchasable refill oil is listed for the waterless commercial machines at all.
2. Not one setting. The buildings are different instruments. Four properties with the same composition at the same intensity will produce four different impressions, because perceived strength is made by the room rather than by the dial. A lounge full of carpet, underlay, heavy curtains and upholstered chairs takes up fragrance and releases it later; a hard-surfaced modern lounge of marble, glass and metal holds almost nothing and decays fast. Air that leaves a building takes the fragrance with it, so a leaky heritage property and a sealed new one behave oppositely on the same machine. And relative humidity changes how a composition is perceived without changing what is in it — the same scent reads heavier in a damp coastal room than in a dry conditioned one.
3. What travels between properties: the composition, the exclusions, the method, the owner. Four things should be word-for-word identical in every club. The fragrance. The written list of rooms that stay unscented — dining, private dining and bar counters, spa treatment rooms, the gym floor, boardrooms, a heritage library. The method by which intensity is judged, which is to walk in from the car park with a fresh nose and never from inside. And the rule that one named person per property owns the setting, with the key-lock engaged after commissioning.
4. What must be local: the dose, the count, the positions, the hours, the commissioning. Intensity per zone is set in the building, by someone standing outside it. The number of machines follows connected volume and ceiling height, not the group’s average. Mounting positions follow each building’s airflow and its grille layout. Schedule hours follow each club’s actual occupancy, which in a city club and a weekend club are not remotely the same shape. And every property gets its own commissioning period, which is a few weeks of judging and adjusting rather than an afternoon.
5. The honest warning, and the commercial position. If a group standard contains an intensity number, it will be the number that suited the property where it was first set, and the other properties will be wrong by exactly the amount their buildings differ. Standardise the composition and the method; never the dial. On the commercial side: there is no group pricing, no framework agreement, no multi-site discount and no portfolio arrangement published, so each property is specified and quoted on its own merits through the contact page. Everything SOSA composes is alcohol-free, phthalate-free, paraben-free, IFRA-compliant and 0 ppm formaldehyde, made in Pune, and a portion of every order supports girl-child education through Nanhi Kali.
The four ways your buildings differ
When an operator tells me their properties are “broadly similar”, they usually mean similar in size, service and membership. Those are the three variables that matter least here. What matters is what the building does to a thin vapour of fragrance over an evening, and on that measure two clubs of identical floor area in the same city can be as different as a cellar and a conservatory. There are four variables, and a group standard that ignores them is not a standard but a hope.
Mountain Breeze₹849Carpet and underlay, heavy curtains, upholstered wing chairs, timber panelling and decades-old leather all behave as a reservoir. They take odour up and release it hours later, which is why a heritage club lounge can smell faintly of last night at nine the next morning, and why the same lounge needs a lower setting than you would expect: part of the evening’s fragrance is already in the furniture before the machine starts. A hard-surfaced modern property does the opposite. Marble, glass, metal and lacquered joinery hold nothing, so the fragrance arrives and goes, and the room can feel under-scented at a level that would be oppressive in the heritage building. Two properties, one composition, two intensities — and the heritage one is usually the lower of the two, which surprises people.
Aangan₹25,999A space with high air change needs the fragrance replaced continuously, because it is being carried out of the building as fast as it arrives. A tight, sealed space accumulates instead, and a setting that is correct on Monday can feel thick by Thursday. The same machine therefore behaves oppositely in those two buildings, and air conditioning both helps and hurts — it distributes fragrance evenly through a volume and it removes it faster than a still room would. On top of that, relative humidity changes perception rather than content: an identical composition reads heavier and sweeter in a damp monsoon or coastal room than in a dry conditioned one. A coastal property and an inland one on the same dial will be described differently by the same member, and both descriptions will be accurate.
Vaayu₹11,999Bodies change a room. A lounge at capacity holds more warmth, more moisture and a great deal more competing personal fragrance than the same lounge at four in the afternoon, and senior members wear their own perfume, which the room must not argue with. A property that fills every evening and sits empty all day therefore wants a different shape of operation from a business club that runs steadily from nine to seven — not a different fragrance, and usually not even a different peak intensity, but different hours and a different pause pattern. This is the variable most easily solved by hardware rather than judgement: run windows of 1h, 4h, 8h or 24h with a choice of days on the zone unit, and programmable work and pause cycles with daily schedules on the HVAC unit.
Why the street outside changes the dose inside
There is a fifth difference between properties which does not sit inside the building at all, and it catches operators out because no survey records it. Perceived strength is set by the step between two spaces rather than by the absolute level in either. A lobby feels clearly scented because the street was not; a lounge feels calm because the corridor was louder. That means the arrival dose at a club entered from a hot, dusty, traffic-heavy street is not the same arrival dose as at a club entered from a cool landscaped forecourt or from an air-conditioned basement car park. The nose arriving at the first has been saturated by something assertive and needs a clearer signal to register a change; the nose arriving at the second has been in nothing much and will find the same level emphatic.
This is also why I distrust fragrance decisions made at a group head office. A composition judged on a blotter around a committee table tells you very little about how it will behave as a thin vapour across a large volume several hours later, and nothing at all about how it will land after a member has crossed the particular approach to a particular door. The group can and should choose the composition centrally — that is a brand decision and it belongs at the centre. But the step into each building is a local fact, and it is one of the reasons the commissioning visit has to happen at the property, in the evening, with somebody walking in from where members actually walk in from.
One more point about what members can and cannot detect, because it bears directly on how much consistency you need. Members do not compare two of your clubs side by side; they compare the second to a memory of the first. Memory is good at identity and poor at intensity. It will reliably tell them “this is our club” and it will almost never tell them “this is two notches stronger than Bengaluru”. That asymmetry is the whole permission structure for this page: hold the thing memory is good at, and let the thing memory is poor at be set by the building.
What is identical, and what is local
This is the table I would put at the front of a group scenting standard. Every row is a decision somebody will otherwise make by default, and the left column is the only question that matters: does this belong to the brand or to the building? The last row is the one most groups get backwards, and it is the reason this page exists.
| Decision | Central or local | Why | Who signs it off |
|---|---|---|---|
| The composition ★ | Central, identical, held for years | Recognition accumulates only if nothing changes; the cross-property member is the whole point | Group, once |
| The unscented list | Central, identical, written | Dining, bar counters, spa treatment, gym floor, boardrooms and a heritage library are excluded everywhere for the same reasons | Group, once |
| The judging method | Central, identical | Walk in from the car park with a fresh nose; never judge from inside the room | Group, once |
| Ownership and the key-lock rule | Central rule, local owner | One named person per property, setting recorded and locked after commissioning | Group rule, local name |
| Machine count and mounting positions | Local | Follows connected volume, ceiling height, door positions and where each building’s air actually goes | Property, with the drawings |
| Schedule hours | Local | A weekend club and an all-day business club have different occupancy shapes | Property |
| Intensity per zone | Local, always — never a group figure | Absorbency, air change, humidity and the step from outside differ per building; a group number gets one property right | Property, over a commissioning period |

When the hardware itself should differ
Operators often assume that consistency implies identical equipment, and it is worth saying plainly that it does not. Coverage is published in volume rather than floor area, and that single fact dissolves most of the apparent inconsistency. Two clubs of 9,000 sq ft can need entirely different schemes. If the first is a single connected volume served by one air handling system, the sensible answer is one Aangan at ₹25,999 connected into the HVAC, rated to up to 3,000 m³ which is roughly 8,000–10,000 sq ft, with an 800ml reservoir, under 42 dB, DC 12V at 14W and a programmable board carrying work and pause cycles and daily schedules. If the second is the same area spread over three floors with closed doors, a lift core and a galleried stair, then it is not one volume at all — a closed door is a genuine boundary and an open plan is a single volume however irregular — and the answer is several Vaayu zones at ₹11,999 each, rated to up to 1000 m³ apiece and commissioned separately. Meenar at ₹38,500 is the larger-property option and is specified on enquiry rather than from a page.
Double-height spaces are where this bites hardest in a portfolio, because they are exactly the spaces a group is proudest of and exactly the ones a floor-area comparison conceals. A double-height entrance hall or a galleried staircase consumes coverage that a square-foot figure hides entirely, and lift shafts and open stairwells behave as chimneys: warm air rises through them and carries fragrance to floors nobody intended to scent. A property with a grand stair and a property with a low flat ceiling can have the same plan area and need a different number of machines, and the group standard should expect that rather than query it. I will not publish a machine count as a formula for any property, let alone for a portfolio — the honest number depends on connected volume, ceiling height, door positions, one air system or several, and how many hours each zone is genuinely occupied.
Two clarifications for a group that is about to write a procurement note. First, the air handling connection on the HVAC unit is a real mechanical integration — the machine introduces its dry mist into air the building is already moving. It is not a digital one, and none is offered: there is no network interface, no building management connection and no automation protocol on any SOSA machine, so there is nothing a group IT or controls function needs to standardise. Scheduling lives on each device. Second, certification: CE, RoHS and SGS are published for the zone unit only, and no certifications are published for the larger two units — worth knowing before a group submittal assumes otherwise. And the water-based Hotel Collection fragrance oils are a separate system entirely, three to six drops into an ultrasonic machine’s water tank; they are not for reed diffusers and not for neat waterless nebulising.
Writing the group standard — and the gaps
If a group asked me to draft the scenting section of its brand standards, it would be about a page long and would read like the table below. The order matters: the building work comes before the identity work, because fragrance laid over a musty property produces a mixture that reads as a cover-up, and in a portfolio that failure is reputational rather than local — a member who meets it at one club will attribute it to the group. The last row names the two things that are not published, both of which a group procurement function will ask for in the first conversation.
| Clause | What it says | Why it is written this way | Cost |
|---|---|---|---|
| 1. Building condition first, at every property ★ | Moisture, air change, drain traps, carpet drying, a fresh-air purge before opening — audited per club | Fragrance over musty reads as concealment, and in a group the member blames the brand rather than the branch | No purchase |
| 2. One composition, group-wide | Named once, changed almost never, specified for the waterless machines per property | A signature is a decision held for a decade; the cost of changing it arrives years later, when members have bonded to it | Quoted |
| 3. The unscented list, group-wide | Dining, private dining, bar counters, spa treatment rooms, gym floors, boardrooms, heritage libraries | Identical exclusions everywhere make the scheme credible to every chef in the portfolio at once | No purchase |
| 4. Intensity: local, commissioned | Set at the property over a commissioning period, recorded in writing, key-locked afterwards | Absorbency, air change, humidity and the step from the street differ per building | No purchase |
| 5. Hardware: local, by volume | Vaayu zones where there are closed doors and floors; Aangan where one air system serves the scented areas | Equal floor areas can be unequal volumes, and a grand stair is a chimney | ₹11,999 · ₹25,999 |
| 6. One named owner per property | Who sets it, who holds the key, who may not change it, and the refill cadence as a review point | A scheme is only a system once it is written down with a name against it | No purchase |
| No group terms, and no listed commercial refill: the honest gaps | No group pricing, framework agreement, multi-site discount, portfolio arrangement, dealer programme or service contract is published, and no purchasable refill oil is listed for the waterless machines — each property is specified and quoted on its own | Said plainly, because a portfolio buyer expects a schedule of rates and there is none to publish; quoted fragrance is the norm in commercial scenting rather than an evasion | Quoted |
Versailles
A group once sent me a complaint summary from three of its clubs and asked which fragrance was at fault. The complaints were opposite. At the first property members said the lounge smelled of nothing. At the second they said the lobby was overwhelming. At the third nobody had said anything at all, which is the result you actually want. One fragrance, one intensity, three buildings — and the operations director had done exactly what a careful person does, which is write the setting into the standard so that nobody could get it wrong.
The third property was a steel-and-glass building with high air change. The first was a carpeted heritage club with heavy curtains that had been quietly absorbing fragrance for a fortnight and releasing it at times nobody was present. The second had a narrow vestibule off a very busy road, so the step from street to lobby was enormous and the dose that read as discreet elsewhere read as a statement there. Nothing was wrong with the composition. The standard had simply fixed the one variable that belonged to the buildings.
What we changed was the shape of the document rather than the fragrance. The composition stayed. The unscented rooms stayed, word for word, which matters more in a group than in a single club because it is what stops one ambitious general manager scenting a dining room and setting a precedent. And the intensity clause became a method instead of a number: commission over a few weeks, judge only by walking in from the car park with a visitor, write the setting down, turn the key-lock, and review it when the refill is changed. Three months later the complaint file was empty at all three. Everything we make is composed in Pune, and a part of every order funds a girl’s classroom through Nanhi Kali.
