What kind of alcohol has the most alcohol by volume?
Everclear or other PGAs are the highest you are going to find, but your friend won’t be able to take a shot of it. Even if he manages to get the shot down, it won’t make him piss drunk, no single shot can do that, unless your friend has no tolerance to alcohol and almost no body fat, then I still doubt it. For ideas, if your friend drinks coke, punch, or something else non-alcoholic, put a little bit of alcohol in his drinks, I don’t advise drugging someone like this, but it is about the only way you are going to get him piss drunk if he will only take a single shot willingly. Just try and convince him to drink more.
You won’t find anything stronger than Everclear…it’s 190 proof or 95% alcholo by volume. You also DO NOT drink it straight. You can in that one is physically able, but then, one is physically able to do shots of gasoline, too, but it’s about as smart. The only thing stronger is pure, non-denatured anhydrous ethanol that is 100% alcohol only until the cap is removed…it attracts water from the air until it equalizes at 96.5% This is only available through laboratory supply houses and only with a monstrous paper trail of permits and licenses…and last time I checked, it was somewhere around $115 a gallon.
