By definition, which grain must make up at least 51 percent of a bourbon's dry ingredients?

To be called bourbon, a whiskey must meet a specific set of standards. At least 51 percent of the total grain bill must be corn, it must be distilled to 160 proof or less, and it needs to age in a new charred white-oak barrel.
