This study aimed to understand the effects of the day of the week, season, and weather factors on the sale volumes of various types of alcohol. The data was taken from a combination of payment big data from Lotte Mart, a large retailer, and synoptic meteorological observation data. The results of the study were as follows: First, alcohol sold more on weekends, in winter, and when the humidity was high. Second, when weather factors were used in the analysis, the influence of seasonal factors decreased. Third, the effects of season and weather on alcohol sales were different for each type of alcohol. Beer, unlike other types of alcohol that sold more in winter, sold more in summer. Liquor and soju, which are distilled liquors, had the same factors influencing sales. Traditional liquor sold more in winter, and soju and beer sold more, especially on weekends. This study is significant in that it comprehensively identified the trends of alcohol consumption by simultaneously examining the consumption of several types of alcohol.
