Shownotes:   >99% of any distilled spirit is comprised of ethanol and water and therefore is of no interest from an analytical organoleptic point of view. Direct injection will detect a small number of abundant fermentation fusel alcohols (high ppm levels), which may not be main contributors to perceived aroma. Therefore:  An Enrichment Method is Required!!  […]
