Abstract
ABSTRACT This study investigated the relationship between sensitivity to the bitterness of 6‐n‐propylthiouracil (PROP) – a genetically determined trait used as an index of general taste acuity – and a range of oral sensations elicited by 16 varietal red wines. Seventeen subjects were trained using descriptive analysis (DA) techniques and developed a lexicon consisting of three taste and 10 tactile attributes representing sensations experienced both in‐mouth (IM) and after expectoration (AE). Analysis of variance showed that PROP super‐tasters (ST) ( n = 8) rated 11 of these 13 sensations differently compared to PROP nontasters (NT) ( n = 8), specifically acidity, saltiness, heat/irritation, tingle/prickle, particulate IM, particulate AE, smoothness IM, smoothness AE, grippy/adhesive, mouthcoat and overall astringency. The greater sensitivity of ST to the textural components of red wine is discussed in the context of greater lingual acuity and implications for DA panels, psychophysics and wine consumer behavior.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
