Bourbon is an American type of whiskey. As specified by US trade law, it must be made from at least 51% corn or maize with the remainder consisting of wheat, malted barley or rye. Once distilled it is aged in new charred white oak barrels for a minimum of 2 years. In this sense the production of Bourbon is very similar to Scotch or Irish whisk(e)y which are also aged in charred barrels. Traditionally Bourbon is made only in the state of Kentucky. Curiously when thinking about bourbon, many people think of Jack Daniels – however this is a Tennessee whiskey. The difference being that the newly made Tennessee whiskey is dripped through giant containers packed with sugar maple charcoal. This painstaking process takes 10 days and during this time the whiskey absorbs the essence of charcoal giving it a unique aroma and flavour.
