Is there a correct graph which describes various drinks I was going through list of drinks [Alcholic] . Was thinking is there any graph which subtly defines to which category of drinks they belong to . A more generic to top down approach of specific type .

There isn't going to be (or rather it wouldn't be visually appealing enough) a source for what you want. Your best bet is to search "::insert alcoholic family you wish here:: Infographics." When you do you will find that some people have made things like this from PopChartLabs! They have two great ones for Whiskey and Scotch too.
