Michter’s Toasted Barrel Sour Mash Whiskey is made by taking Michter’s US 1 Sour Mash Whiskey and then aging it for an additional period of time in a second custom made barrel. This second barrel is assembled from 18-month air-dried wood and then toasted but not charred. Several different levels of toast for the second barrel were evaluated to determine the one that would best display the elegant nuances of this remarkable whiskey.
