Bourbon
American whiskey made from a
mash of at least 51%
corn, with the remainder being any other
grain.
Rye and wheat are most common, and most contain a small amount of
malted barley to aid in the
fermentation process. It must be distilled to no more than 80%
ABV, aged in
charred new American oak containers with an entry ABV of no more than 62.5%, and bottled at no less than 40% ABV. Bourbon may be produced anywhere in the United States. For more information, see "
