How this molecule is described
Sources disagree about odour more often than they disagree about chemistry. Rather than show one answer, here is every description on file with how many ingredient records carry it.
Same molecule, unified here — previously counted and displayed as separate compounds.
Published thresholds
11 measured values from the literature. Grouped by what was actually measured — a threshold smelled in clean water, tasted in the mouth, or measured in a real food are three different quantities and are not pooled.
Orthonasal, in clean water
200 ppbThe reference measurement — smelled in water. OAV is computed against this.

In a food matrix
0.410 ppb – 1086 ppbMeasured in a real food, where the matrix shifts detection — not a clean-water value.

Measured impact first, then profile shareEvery ingredient known to contain alpha-terpinolene. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of alpha-terpinolene in it.
