A sweet, vinegary smell that often accompanies acetic acid. It exists to some extent in all wines and in small doses can be a plus. When it is strong and smells like nail polish, it's a defect.
Ethyl acetate is the organic compound with the formula CH3CH2OC(O)CH3. This colorless liquid has a characteristic, not unpleasant smell like certain glues or nail polish removers, in which it is used. As the ester derived from ethanol and acetic acid, EtOAc, as it is commonly abbreviated, is manufactured on a large scale for use as a solvent.
