A beta regression model was then used to analyze the relationship between inferred personality traits and wine ABV preferences.\n\n\nResults\nThe results reveal that openness and agreeableness are positively associated with higher ABV preferences, while extraversion and neuroticism show negative associations. Conscientiousness did not exhibit a significant relationship with ABV preferences.\n\n\nConclusions\nThe findings indicate that personality traits significantly shape consumer evaluations of wine intensity and validate the predictive power of AI‐based personality inference. This research contributes to consumer behavior theory and offers practical implications for developing personalized wine recommendations and targeted marketing strategies in digital retail environments.\n\n"]
