F.L.A.R.E. Lab — Flavour, Localisation, Afterburn, Response & Evolution — is an interactive R&D and learning tool designed to explore how peppers and other chemesthetic ingredients create heat, flavour and mouthfeel over time. Rather than treating “spiciness” as a single number, it separates the sensory event into heat intensity, onset, peak, decay, afterburn, oral location, flavour architecture and non-pepper sensations such as cooling, sting, tingling and warming. This reflects the underlying science: chemesthetic signals interact with taste and aroma and can change not only perceived intensity, but also flavour quality, timing, localisation and identity.

The tool allows up to six peppers to be blended and compared simultaneously, with fresh, dried, smoked, roasted, fermented and other processing states considered alongside dose, serving temperature, matrix and formulation effects. It can also model non-pepper heat and cooling inputs such as black pepper, ginger, mustard/wasabi-type pungency, alcohol and menthol, showing how these different sensory mechanisms overlap or diverge through time. Heat curves, flavour radar profiles, mouth heat maps, dose-response behaviour, processing comparisons and the Sensory Convergence Map make it possible to see not only how hot a formulation becomes, but what kind of heat it produces, where it is felt, how long it lasts and how the flavour profile evolves around it.

A major focus of F.L.A.R.E. Lab is the relationship between heat and flavour perception. Its Flavour-Impression Time Lens compares intrinsic flavour release with the flavour likely to remain perceptually accessible as chemesthetic intensity rises, while separately tracking identity confidence and possible bitterness intrusion. This makes the tool useful for formulation strategy: a flavourist can explore whether a concept is heat-led or flavour-led, whether a rapid wasabi-like attack differs from a lingering capsaicin burn, how cooling or matrix changes reshape the experience, and whether processing improves or suppresses desirable flavour characteristics. The outputs are intended as comparative, literature-informed R&D models, not substitutes for trained sensory panels, analytical testing or formulation-specific validation.
