Vinegar was prepared from the fruits produced in Gangwon province, and major metabolite and aroma components were investigated for acetic acid fermentation. In the case of Meoru-Bokbunja vinegar, the Lalanine content was greatly changed by acetic acid fermentation. Acetic acid had the highest content (43%) of total aromatic components, and the contents of ester compounds, such as ethyl acetate and isoamyl acetate, were significantly increased after fermentation. Omija-Makgeolli vinegar produced linalool and hexanoic acid by fermentation, and terpenoid compound was prevalent (41.5%). L-alanine was also increased in Omija-Makgeolli vinegar, similar to that of Meoru-Bokbunja vinegar. Terpene compounds, such as terpinel-4-ol and α-terpineol in Omija-Makgeolli vinegar, and ethyl acetate in Meoru-Bokbunja vinegar, were identified as major components in each aromatic formulation.
