The invention discloses a method for quickly evaluating quality of primary pulp wine by using a pigment array sensing technique. The method comprises the following steps: (1) selecting two or more gas-sensitive pigments, and integrating a pigment sensor array; (2) establishing a standard fingerprint map for different grades of primary pulp wine; (3) establishing a primary pulp wine grade identification model; and (4) identifying the grade of the detected primary pulp wine. The pigment sensor array is utilized to detect the corresponding response signal of ethanol and ethyl hexanoate in the primary pulp wine; and the quality of the primary pulp wine is evaluated by analyzing the contents of the ethanol and ethyl acetate, thereby implementing quickly distinguishment on the grade of the primary pulp wine and providing instructions for white wine production.
