Produced in the United States since the 18th
century, bourbon whisky is generally referred to as whisky produced
in Kentucky. Bourbon whisky has been distinguished as a product of
the United States, and similar to scotch must meet specific
criteria to bear the name bourbon upon its label.
Criteria that must be met for a whisky to be considered bourbon
include:
• Spirit must contain a minimum of 51% corn.
• Cannot be more than 80 proof after distillation.
• Spirit must be aged in new charred oak barrels.
• Spirit cannot include caramel coloring.
• Spirit may not enter barrels with an alcohol level higher than
125 proof.
• Spirit may not be bottled if it contains lower than 40%
alcohol.
• In regards to age, a bottle must state the age of the youngest
whisky within the spirit.
Most commonly, bourbon whisky will contain a minimum of 40% alcohol
by volume. However, some distilleries produce bourbon that will
exceed this amount. Bourbon whisky labeled as “barrel proof” tend
to contain a higher content of alcohol. This occurs when the
bourbon is not diluted with water prior to having been bottled. The
majority of commercially produced bourbon whisky is diluted with
water prior to the bottling process.
Bourbon whisky is generally gold to brown in color. It receives its
characteristic caramel tone through the aging process. During the
aging process, the wood of the barrels turns the bourbon from clear
to brown. The longer it is aged, the darker it becomes.
While the majority of bourbon whisky is distilled in Kentucky,
other states that commercially produce bourbon include
Pennsylvania, Virginia, Kansas, Indiana, Ohio, and New York.
However, the largest distilleries that produce bourbon whiskies
include the Jim Beam Distilleries, and the Heaven Hill
Distilleries.
