An act of US Congress in 1964 declared bourbon to be "America's Native Spirit," i.e. America's official drink.

`Bourbon whisky', `rye whisky', `wheat whisky', `malt whisky', or `rye malt whisky' is whisky produced at not exceeding 160 deg. proof from a fermented mash of not less than 51 percent corn, rye, wheat, malted barley, or malted rye grain, respectively, and stored at not more than 125 deg. proof in charred new oak containers; and also includes mixtures of such whiskies of the same type.

Distilled spirits in which at least 51% of the sugar in the wash comes from corn and the distillate is aged in charred oak barrels.
