<P> Ethanol can not be concentrated by ordinary distillation to greater than approximately 96 % by weight because at that concentration , the vapor has the same ratio of water to alcohol as the liquid , a phenomenon known as azeotropy . The highest concentration of ethanol generally available for human consumption is 190 proof ( 95 % alcohol by volume ) , which is about 92.4 % ethanol by weight . </P>
