Does Alcohol Type Matter? Investigating the Effects of Beer, Wine, and Liquor on Liver Health

Purpose: Excessive alcohol intake is detrimental to liver health, but the differential impacts of types of alcohol on hepatic health remain understudied. Beer, wine, and liquor are the most common alcohols consumed worldwide, with each varying substantially in alcohol content and chemical profile, and given their popularity, an understanding of alcohol types and general liver health is needed. Search Methods: As such, we conducted a comprehensive narrative review focusing on pre-clinical and clinical studies on alcohol type and liver health by searching major research databases (PubMed, Google Scholar, Cochrane Library) for key terms associated with our topic and utilizing snowballing between August 2025 and September 2026. Search Results: Our search strategy yielded 301 total articles, of which 74 were included in the pre-clinical and clinical sections of this study, with 277 articles excluded. Discussion: Overconsumption of alcohol is detrimental to the liver regardless of type. Although some research indicates low and moderate red wine consumption is less deleterious, caution must be applied due to a variety of confounding factors. Liquor was found to be harmful to the liver across pre-clinical and clinical studies, while beer’s impact was largely negative albeit varied based on many factors. Several gaps emerged, including a lack of studies on differing types of liquors, non-red wines, beers, and hard seltzers, as well as pre-clinical experiments in females. This review highlights that all alcoholic beverages may not uniformly impact the liver, and that more research is needed to determine how different alcohol types impact liver health.
