Class 1 - Aromatic, Fragrant, Fruity, Floral
0110 Alcoholic OTW The general effect of ethanol and higher alcohols
-Spicy OTW Allspice, nutmeg, peppery, eugenol. See also 1003 Vanilla

0140 Fruity OT Of specific fruits or mixtures of fruits

Class 5 - Phenolic
0500 Phenolic OT
-Tarry OT Pitch, faulty pitching of containers.
