Bourbon is mostly made from corn, at least 51% corn. Rye whiskey is mostly or entirely made from Rye. They differ in many other details - for example Bourbon must be aged in new, charred American Oak barrels and made in the US, Scotch must be made in Scotland, but the big differences are the grains used.
Bourbon - Grain Selection and Mixture (Mash Bill) Each distillery has its own recipe for the grain mixture. The law requires a Kentucky straight bourbon whiskey to have a corn content of at least 51%. However, the corn content is usually higher (between 60% and 80%). Further components of the mash bill are rye and malted barley, which each make up between 10% and 15%.
