Abstract

A method for the specific extraction of volatile thiols by use of p-hydroxymercuribenzoate has made it possible to identify certain flavor-active volatile thiols in Champagne wines. Benzenemethanethiol, 2-furanmethanethiol, and ethyl 3-mercaptopropionate were present in these wines at concentrations considerably higher than their perception thresholds. Their concentrations increased gradually in proportion to the bottle aging period and sharply as a result of disgorging. The contribution of these volatile thiols to the empyreumatic nuances of the bouquet of aged Champagne wines was demonstrated for the first time.
