Named for the virgin oak barrels sourced from Kelvin Cooperage in Louisville, Kentucky, The Balvenie's Sweet Toast of American Oak gains its unique flavor from the barrels' deep toasting. The barrels undergo pre-toasting in Kentucky before traveling to Dufftown for an additional deep toasting at The Balvenie Cooperage. Filled with single malt that has matured for 12 years in ex-bourbon barrels, they are left to rest for several months before being bottled. This innovative whisky was the brainchild of Apprentice Malt Master Kelsey McKechnie and is one of three Stories single malts introduced by The Balvenie in May 2019.
