A multidimensional system consisting of a 45-m polar capillary column linked to a 50-m nonpolar capillary is evaluated with regard to its practical usefulness in Pisco aroma analysis. Fifty-four componente can be separated and identified from the information resulting from use of such a multidimensional procedure in addition to the gas chromatography-mass spectrometry technique. Eighteen of these components including esters, alcohols, terpenes, acids, aldehydes, and miscellaneous compounds are detected for the first time in Pisco.
