Blanton's Honey Barrel is a Kentucky straight bourbon presented in the rich, sweet style many bourbon drinkers expect. Bourbon is made primarily from corn and matured in new charred oak barrels, which commonly gives it notes of vanilla, caramel, and baking spice.
For a novice drinker, this is best understood as a fuller, sweeter American whiskey style rather than a smoky or grassy one. Expect oak-led richness and a rounded profile shaped by barrel aging.
