The odor threshold and agreeability of aroma components in Korean Yakju were measured in Null-Yakju, 19% ethyl alcohol solution, 20℃ distilled water and 50℃ distilled water by 20 panels. The measurement of the odor threshold in Null-Yakju was as follows: Formal-dehyde 5ppm, acetaldehyde 20ppm, ethylacetate 30ppm, ethyl alcohol 5g/ℓ, acetone 7ppm, diacetyl 0.2ppm, n-propanol 20ppm, iso-butanol 80ppm, iso-amyl alcohol l0ppm and dimethyl sulfide 2ppm were found. The most agreeability of amyl alcohol, ethyl alcohol and acetaldehyde were 80∼350ppm, 2.6 X 10⁴∼1 × l0^5ppm and 75∼160ppm.
