Straight Bourbon Whisky must contain at least 51% and at most 80% of the raw material corn. In addition, the distillate must not contain more than 63% alcohol by volume in the bottle during bottling.
Straight means as much as purely, whose storage must amount to at least 2 years in flamed oak barrels.
Aging periods of less than 4 years must also be indicated on the label. In addition it is forbidden to use dyes and the prescribed alcohol content in the bottle is 40-62.5 percent by volume.
An important difference to Scotch is the fact that Bourbon may only be matured in new American white oak barrels. At least 2 years must be stored a genuine Bourbon in such barrels.
