Interesting, in the US 1 drink is pretty standard. 1 pint of beer, 1 glass of wine, 1 hard liquor drink. Obviously, the amount of actual alcohol can vary pretty greatly (even in beer, eg. a pilsner vs an IPA). This is definitely focused on "servings", which seems like an easy shorthand to track what you're drinking at a level that's comfortable for you. Of course, if you don't remember how much you drank last night, then, that might be an issue.
