In this study, vinegar was produced using urushiol-free fermented Rhus verniciflua extract to create a lacquer with added value. The effect of manufacturing conditions on the quality of vinegar using detoxified R. verniciflua extract for fermentation was investigated. The acidity of the vinegar for inoculations with various liquid starter contents was 4.8~4.9%, and it was similar among all treatment groups. The acidity of vinegar was higher when the initial alcohol content was high. The acetic acid yields were 82.8%, 84.4%, 77.7%, and 69.5%, and the maximum yield was observed when the initial alcohol content was 6%. For acetic acid fermentation using different amounts of detoxified R. verniciflua extracts, the acidity of the vinegar with the extract after fermentation was 5.3~5.9%. However, the acidity of vinegar without the extract was 5.5%. The intensity of the brown color was high for vinegar without the extract. Hunter's L values were high for vinegar with an extract content of 2%. Acetic acid (53.3~65.8 mg/mL) was the predominant acid. Arginine ($190.3{\sim}333.3{\mu}g/mL$), proline ($125.6{\sim}290.8{\mu}g/mL$), alanine ($126.1{\sim}270.9{\mu}g/mL$), and glutamic acid ($159.0{\sim}262.4{\mu}g/mL$) were the predominant amino acids in detoxified R. verniciflua vinegar.
