Selected or trained assessors are suited to consistent discrimination and description, while target consumers are suited to liking, preference, and use-context questions; one group should not be treated as a substitute for the other.
The same person may contribute to more than one kind of session, but training, instructions, task, and inference must remain distinct.
ASTM E2943 — Consumer liking and preference require a defined target group and comparison frameISO 11136 — Controlled hedonic tests measure liking through stated consumer responsesISO 13299 — Descriptive profiles characterize attribute type and intensityISO 8586 — Trained assessors require explicit selection and trainingDan Callaway — Blending expertise is apprenticeship plus experimentationNancy Fraley — Old-world sensory discipline can transfer across spiritsNancy Fraley — Sensory expertise combines training, method, and context controlNancy Fraley — Blending judgment develops through mentorship and repeated practiceASTM E2263-25 — Paired preference answers preference, not difference or magnitudeA technically precise sensory profile does not establish market appeal, and consumer enthusiasm does not establish analytical consistency or identify the mechanism of a difference. Pilot design should assign each participant type an explicit role.
Synthesized from public ASTM E2943 and ISO 8586, ISO 11136, and ISO 13299 scopes. It is a method-selection distinction, not a claim of formal standards compliance.
A Zettel is one durable idea in your own words—not a quotation, source summary, or draft-book claim.
