Aroma
Powerful and diffusive, ethereal-fruity, Apple-like odor with a remote resemblance to Pineapple. Esters with traces of free acids will show this very perceptibly in the odor, not so conspicuously in the flavor (in aqueous media). Sweet and somewhat pungent-fruity, AppleIike, almost "gassy"-ethereal taste. In extreme dilution, the taste is merely sweet fruity.
