American bourbon whiskey differs from its Scotch whiskey brother Scotch mainly by the raw material used. Bourbon is made to a greater or lesser extent (at least 51%) from corn, which grows better in America than the barley traditionally used before. However, the corn content must not exceed a percentage of 80%, with a percentage of 65 to 75% being the most common. The whiskey stands out for its sweet fruitiness and savory smoky note, which comes from burning out the barrels. Bourbon whiskey often gets a heavy note from the fact that it is distilled only once.
Bourbon whiskey enjoys great popularity around the world. The mixture of different raw materials and grains such as corn, rye, wheat and barley characterize the diverse flavor variations and give each bourbon an individual character. During production, care must be taken to ensure that the alcohol content does not exceed 80% at any time during distilling, and a certain percentage must also not be exceeded when bottling in the barrels for aging. Bourbon whiskey is aged for a minimum of two years in charred oak barrels. The term "Straight Bourbon" stands solely for the fact that those manufacturing conditions have been met and it contains no additives. "Single Barrel Bourbon" represents the American equivalent of Single Cask Scotch. This means bourbon whiskey that was bottled from only one barrel.
