Adjust Sensory Lab — How We Calibrate Flavor
Most disposable vape brands pick flavor concentrates from a supplier catalog, label them with a fun name, and ship. We run every Adjust flavor through a 4-stage sensory protocol before it goes into production — the reason MySour actually puckers and MyCool's Cherry Strazz tastes like a black-cherry and strawberry mix instead of generic "red candy."
Stage 1 — Reference-note collection
Every flavor that enters the lab starts with a physical reference. For "Watermelon Ice," that's actual watermelon flesh purchased from three different produce sources (to account for varietal differences) plus a polar mint extract. For "Sour Lush Gummy," it's a bag of sour-gummy candy from the brand most people picture when they hear "sour lush." For "Tigers Blood," it's the classic snow-cone syrup reference, sourced from a U.S. snow-cone supplier. Every profile in the adjust flavors range clears this same reference step before Adjust Vape ships it.
The reference doesn't go into the e-liquid — we use it to define the flavor target. A sensory analyst tastes the reference and writes a profile sheet: dominant notes, secondary notes, finish length, sweetness range, sour range, and how cold or warm the perception is. That sheet becomes the spec the lab matches against.
Stage 2 — Concentrate matching
Our flavor concentrate supplier sends candidate blends — usually 4–6 variants per target. Each one tries to match the reference profile from different angles. We test them in a controlled rig at the same coil temperature, airflow, and salt-nic concentration the final device will use, so what we taste in the lab matches what the customer tastes at home.
This stage rejects more candidates than any other. A "Mango Magic" candidate might nail the mango note but miss the magic — the secondary tropical layer we wanted underneath. A "Sour Apple Ice" candidate might be sour enough but lose all green-apple character past the first puff. Most flavors take 8–12 rounds of supplier iteration before we have a candidate worth advancing.
Stage 3 — Panel scoring
Once a concentrate matches the target on the analyst's bench, it goes to a 5-person tasting panel. Panelists are diverse on the dimensions that matter for vape flavor: age, prior vape experience, and primary cuisine preference (sweet, savory, sour). They score the candidate blind against the reference target on six axes:
- Recognition — would a customer say "yes that tastes like X" within 2 puffs?
- Faithfulness — how close to the reference does it land?
- Consistency across puffs — does it taste the same on puff 1 and puff 30?
- Throat feel — comfortable at 5% salt nic?
- Coolness layer fit — does the menthol (if present) integrate with the flavor or sit on top of it?
- Aftertaste — what's left in your mouth 60 seconds after the last puff?
Each axis scores 1–10. A blend needs an average above 7.5 with no axis below 6 to advance. Roughly one in five blends that reach this stage actually pass — most fail on consistency-across-puffs (the second or third puff tastes muted) or aftertaste (a sweet plasticky finish that doesn't match the reference).
Stage 4 — Production pilot
Approved blends graduate to a small production pilot — typically 200 devices off the same coil hardware and pod size that the retail unit will ship with. The pilot lets us catch two failure modes that the lab rig can't:
- Coil-saturation drift. A flavor that tasted right in 5 mL bench tests might shift when the e-liquid sits for two weeks in a 28 mL pod. We let pilot units age for 14 days then re-taste.
- Hardware interaction. Certain flavor compounds react with specific coil alloys over time. We watch for these and reformulate if the aged taste drifts more than 0.5 points from the panel score.
If the pilot holds the profile through 14 days and 200 puffs per device, the flavor goes to full production. If it drifts, we send it back to the supplier for reformulation. About 70% of pilot flavors pass on the first try; the rest go back at least once.
Why the lab exists
This protocol is more expensive and slower than the industry standard of "pick a concentrate, slap on a label, ship to test market." It's the difference between brands that release 30 new flavors a year (and have a hit rate of maybe 4) versus brands like us that release 6–10 new flavors a year with a near-100% retention rate after launch.
The trade-off the lab buys: when you order a Sour Lush Gummy MyCool and it tastes like the candy you remember from a corner-store wax-paper bag, that's not luck. That's 12 weeks of bench work followed by a five-person panel saying "yes, this matches" — for every single SKU on the catalog.
