The present invention relates primarily to a method for obtaining a volatile fraction from a juice and/or an alcohol-containing beverage, comprising or consisting of the following steps: (a) distilling a mixture of substances from the juice and/or the alcohol-containing beverage, wherein the distillation is performed by a spinning cone column; (b) contacting the mixture of substances from step (a) with a sorbent to obtain a loaded sorbent; and (c) contacting the loaded sorbent from step (b) with a liquid desorbent to obtain the volatile fraction, wherein desired ingredients of the volatile fraction are concentrated as compared to the juice and/or alcohol-containing beverage such that an addition of 0.1% by mass or less of the volatile fraction to any food preparation produces a perceptible odor impression and/or taste impression in a test subject.
