Ask most people what matters in a lab and they'll tell you about equipment, services, and compliance. All true. But in flavours and fragrances, there's a variable that gets far less attention than it deserves: the room itself.

Because here's the thing, human senses are not objective instruments. Decades of crossmodal perception research have shown that what we see changes what we taste and smell. Colour shifts flavour perception. Red environments have been shown to make food taste sweeter; blue tends toward the opposite. Ambient lighting alters how intense an aroma seems. Even the weight and colour of the vessel something is served in changes how people rate its flavour.

For most workplaces, this is trivia. For a flavour and fragrance facility, it's a design brief.

The case for neutrality, in the right places

If your panellists are evaluating a seasoning profile in a room with strong colour, dramatic lighting, or lingering material odours, the room is participating in the tasting. That's why sensory evaluation spaces lean on controlled, neutral conditions: consistent colour-balanced lighting, muted finishes, and surfaces chosen as much for what they don't do (off-gas, absorb odours, reflect colour casts) as for how they look.

Material choice is critical here. Vinyl flooring, sealed worktops, and low-VOC finishes are maintenance and sensory decisions. A tasting room that smells faintly of adhesive for six months has a data quality problem and a snagging one.

Airflow and adjacencies matter just as much. A tasting area next to a frying application zone needs deliberate zoning, pressure and extraction strategy, and a layout that keeps aroma-heavy processes downstream of evaluation. Process flow is about efficiency and protecting the integrity of what happens in each room.

The case for personality, everywhere else

None of this means an flavours & fragrances facility should feel like a void. Quite the opposite. The same science that argues for neutrality in the tasting booth argues for character everywhere else because environment shapes mood, and mood shapes creative work.

Circulation spaces, collaboration areas, offices and breakout zones are where colour can do its proper job: wayfinding, energy, identity. A strong accent colour on a storage wall or along a circulation spine gives a facility coherence and personality without ever entering the controlled environment. Brand colour, used with restraint (a run of joinery, furniture details, a writable wall) connects the space to the business without contaminating the science.

The best flavour and fragrance facilities we've seen (and built) treat this as a gradient, expressive at the front door, calm in the labs, near-invisible in the sensory spaces. Each zone tuned to what the work in it needs.

Designing from the process outward

The common thread is that interior design in this sector is an extension of the method. The palette, the lighting, the finishes and the floorplan all either support the science or interfere with it. Which means the right way to design these spaces is the same way you'd design an experiment: start with what you're trying to measure, control the variables that matter, and be intentional about everything else.

Get that right, and you end up with a facility that protects the rigour of the work, and gives the people doing it a space they are inspired in. In a sector built on the senses, that's the whole point.
