Most well-known for its Kentucky Straight Bourbon, the United States of America has a proud history and heritage in the production of quality whiskies. Introduced by the Irish immigrants, it also has the added 'E' in its whiskey.
Bourbon can be produced anywhere in the USA (yes, outside of Kentucky), and to wear the Bourbon name must be produced using a grain bill with a minimum 51% Corn and aged in first fill, charred and toasted White American Oak barrels for maturation.
Alongside Bourbon, the Americans also produce Rye Whiskey, with very similar base requirements as its Corny brother, but with a minimum of 51% Rye in the grain bill.
