To systematically sort out the research status, technological evolution and development trends in the field of low-alcohol and dealcoholized wines.

Using bibliometric methods, a statistical analysis was conducted on relevant literature in the core collection databases of China national knowledge infrastructure and Web of Science from 1980 to 2025. Visual research was carried out from the dimensions of publication volume, national/institutional cooperation and research hotspots, and the principles, characteristics and application status of mainstream dealcoholization technologies such as reduced pressure distillation，spinning cone column，reverse osmosis and vacuum distillation were reviewed.

The number of publications in the field of low-alcohol and dealcoholized wines had shown a significant growth trend in recent years. The United States and Spain were the core publishing countries with close international cooperation，and institutions such as the Spanish National Research Council，the Center for Biomedical Research in Red and the University of California were the core research institutions. Current research hotspots focused on brewing technology and parameter optimization，flavor quality and stability improvement，etc. Both traditional thermal treatment and new membrane technology dealcoholization had their own advantages and disadvantages，and it was difficult to balance the dual goals of ethanol removal and aroma retention.

Low-alcohol and dealcoholized wines are in line with the health consumption trend. In the future，research should be carried out around dealcoholization technology optimization，flavor quality regulation，product stability improvement and other directions. The results of this study can provide theoretical basis and technical support for the high-quality development of the low-alcohol and dealcoholized wine industry.
