Everclear was a great rock band formed in 1992. Oh, you want to know about the liquor you say? Everclear is a pure grain alcohol that comes in two strengths, 190 proof and 151 proof. Everclear is illegal in the United States, and the purer form of Everclear is rarely found sold even outside of the US. Everclear is incredibly potent and should never be consumed straight.
