This study investigates the flavor compounds of three typical base liquors (<i>Jiangxiang</i>, <i>Chuntian</i>, and <i>Jiaodixiang</i>) by LLE/LLME/HS-SPME, gas chromatography-mass spectrometry (GC-MS), gas chromatography-flame ionization detection (GC-FID), sensory analysis, and odor activity value (OAV). Of the 201 main volatile compounds identified, 37 significant compounds distinguished the three typical base liquors. Acid (441.72 ± 0.17 mg/L), alcohol (5388.88 ± 0.55 mg/L), and ester compounds (8181.64 ± 0.15 mg/L) were respectively marked in <i>Jiangxiang</i>, <i>Chuntian</i>, and <i>Jiaodixiang</i> typical base liquors.
