Descriptors
sweetchemicalharsh

A pungent, fusel-oil alcohol note — sharp and solventy with a slightly sweet, wine-like fermented facet reminiscent of whisky or raw spirits. Very volatile and quickly flashes off, leaving little trail. Rarely used for its odor in fine fragrance; more of a functional/character solvent with a rough alcoholic bite.AI · claude-opus-4-7
