Men metabolize alcohol approximately 30% more efficiently than women I believe, which is what accounts for most of the difference. Also men on average are larger so that accounts for some difference as well
The potential for acute and chronic health impacts from alcohol consumption is really high; supplement & vitamin recommendations are generally about minimums for good health, not maximums to prevent harm.
The average man they base this on is much bigger and heavier than the average woman, and women carry higher body fat, which impacts on alcohol metabolism.
That said, in Australia they now recommend 10 or less per week, and no more than 4 in one day, for healthy adults regardless of gender.
Far from expert but I assume that is mostly based on body mass. Although I thought I remember reading a paper about women handling negative effects of alcohol better. Maybe that was just related to resistance training.

We are still not that advanced when it comes to nutrition. We know even less when it come to the use of alcohol.
