Disclosed are: an alcohol-containing solution which abundantly contains 3-mercaptohexan-1-ol (3MH) that has excellent aromaticity a process for producing the solution a flavoring agent comprising an alcohol-containing solution that contains 3MH abundantly and a process for producing a beverage having improved flavor. Specifically disclosed are: a process for producing a solution containing 3MH and an alcohol, which comprises a step of inoculating a lactic acid bacterium and yeast to an aqueous raw material solution containing S-(3-hexan-1-ol)glutathione and S-(3-hexan-1-ol)-L-cysteine to produce 3MH and the alcohol, wherein the aqueous raw material solution is a solution containing a grape skin extract, the lactic acid bacterium is one capable of converting S-(3-hexan-1-ol)glutathione to S-(3-hexan-1-ol)-L-cysteine, and fermentation is carried out for 0 to 6 days after the inoculation of the lactic acid bacterium to the aqueous raw material solution and subsequently yeast is inoculated to the aqueous solution to carry out alcohol fermentation a process for producing a beverage having an increased 3MH content, which comprises a step of mixing a solution containing 3MH and an alcohol produced by the process with a beverage and a process for producing a fruit liquor using a grape skin extract as a raw material.La présente invention concerne une solution contenant un alcool et une quantité élevée de 3-mercaptohexan-1-ol (3MH) et qui présente une excellente aromaticité, un procédé de préparation de la solution, un aromatisant comprenant cette solution, et un procédé de préparation dune boisson avec un arôme amélioré. Spécifiquement, le procédé de préparation de la solution consiste à inoculer une bactérie dacide lactique et de la levure dans une solution aqueuse de matières premières contenant de la S-(3-hexan-1-ol)glutathione et de la S-(3-hexan-1-ol)-L-cystéine pour produire du 3MH et lalcool, la solution aqueuse de matières premières étant une solution contenant un e
