The total contents of ethyl acetate, ethyl caproate, ethyl caprylate, isoamyl caproate ethyl caprate, isoamyl caprylate, ethyl laurate, isoamyl caprate, ethyl myristate, ethyl palmitate, ethyl stearate, ethyl oleate, ethyl linoleate and β-phenethyl acetate in awamori ranged from 70.67 to 569.72 mg per l at 100 per cent alcohol. The ratio of ethyl acetate content to the total content of 14 ester compounds (ethyl acetate/total esters) ranged from 0.59 to 0.86,and that of ethyl caprylate to the total esters was from 0.98×10^<-2> to 8.26×10^<-2>. Ethyl acetate was the main component of ester compounds followed in descending order by ethyl caprate, ethyl palmitate and ethyl caprylate. Of the higher alcohols, awamori contained only β-phenethyl alcohol in significant quantity.On aging in kame 13 of 16 ester compounds tended to decrease distinctly and the remaining 3 components to show no distinct change, while 3 of 5 higher alcohols tended to increase distinctly. On aging in non-porous containers, howerver, 3 or 16 ester compounds decreased distinctly, and 3 of 5 higher alcohols increased distinctly. In the process of aging, esters underwent hydrolysis in kame but not in non-porous containers.
