Michters US1 Toasted Barrel Finish Bourbon is a groundbreaking whiskey expression. It is made by taking Michters US1 Kentucky Straight Bourbon and then aging it for an additional period in a second custom made barrel. This second barrel is assembled from 18-month air-dried wood and then toasted but not charred. The truly unique and delicious taste of Michters US1 Toasted Barrel Finish Bourbon represents a remarkable achievement given that it is Kentucky Straight Bourbon with nothing extra added or done except placement in a second toasted barrel
