everclear
Although your question is not specific enough, in that it does provide choices for "which of the following", the general rule is that 'hard liquor', such as vodka, gin, and scotch whiskey, for instance, have the higher concentrations, followed by wine and then beer.
190
The strongest alcohol in America is 190 proof Everclear. It is unflavored and colorless. Some areas of the country have banned Everclear, such as Chicago. Some state laws do not allow sales of alcohol above a certain proof.
Not a good idea to do this. Everclear is 180 to 190 proof, or 90 to 95% pure alcohol. It is EXTREMELY flamable. It can blow up and burn you or kill you. I cannot conceive of a use for 'warmed everclear'. It is something to add alcohol to a mixed drink or punch. Be careful.
Who the fack cares what it smells like? I do know, however, if you cut it with lemon juice, even everclear is tolerable.
http://en.wikipedia.org/wiki/Everclear_(alcohol) Everclear- 190 proof Actually there is an alcohol that is more potent then Everclear, it is a Polish Vodka called Polmos Spirytus Rektyfikowany (Rectified Spirit) It is 192 Proof 96% alcohol. You can't get the remaining 4% alcohol out of it as that is the limit. Nothing is higher. I have a bottle and also a few bottles of 190 Proof Everclear. BOTH are ridiculously powerful.
