Aroma compounds in Awamori (one of Japanese traditional distilled spirits produced in Okinawa district) were analyzed and compared on samples distilled in 1989 and ones distilled in 1960-4965. In 12 samples distilled in 1989, the ratio of i-amyl alcohol/i-butyl alcohol (A/B) was lower than 1.99 (average 1.92) for 6 samples, and higher than 2.01 (average 2.62) for other samples. The latter group contained large amounts (average 6.17 ppm) of i-amyl acetate. These differences were largely accounted for by difference in fermentation temperaure of Awamori mashes. In samples distilled in 1960-1965 and stored in glass bottles, the A/B ratio was higher than 2.01 (average 2.25). But the concentration of i-amyl acetate was low (average 2.42 ppm) in these Awamori. These differences were considered to be due to the difference in Awamori yeast used in 1989 and 1969-1965.
