Capillary GC with a flame ionization detector has proven to be very effective in separating fusel oils and the resulting chromatograms show excellent separation of the individual components in a variety of whiskeys (Kahn et al.
These columns using supports such as carbon graphite (Carbopack B) as the adsorbent and Carbowax (Carbowax 20M) as the single liquid phase have been very useful for determining fusel oils (Martin et al.
This explanation for why yeast makes fusel oil is still widely held.
They followed the disappearance of branched-chain amino acids and the formation of fusel oil (difficult and time-consuming measurements to make in those days) during the fermentation of a French Colombard must by the Montrachet strain of yeast.
Castor and Guymon's results shattered Ehrlich's implied one-to-one link between amino acid utilization and fusel oil formation.
In a series of papers, we showed that the major fusel oil components are synthesized along the same metabolic route as their corresponding amino acids.
(Jim Guymon, professor of enology, brandy specialist and connoisseur, had a remarkable nose for fusel oil. I saw him--by tasting--correctly rank three Zinfandel wines according to their content of fusel oil.)
In these same studies we discovered the metabolic route of formation of normal propyl alcohol, the fusel oil component that does not correspond directly to any amino acid.
