Wine has shown antibacterial activity against some bacteria linked to tooth decay and throat infections, but it is not a substitute for dental care or treatment of an infection. Laboratory studies found that both red and white wine could inhibit certain oral streptococci and Streptococcus pyogenes, with organic acids contributing to the effect. Other research found antimicrobial activity from red wine against several bacteria in laboratory oral-biofilm models, but this does not mean drinking wine kills 99% of infection-causing bacteria inside your throat or mouth. Wine may have intriguing antimicrobial properties in the laboratory, but that is very different from using it as medicine.
