Branch & Barrel Colorado Straight Bourbon is a straight bourbon whiskey aged for 5 years and bottled at 46.0% ABV. For a novice drinker, that usually points to a fuller, oak-influenced style than very young bourbon, while still keeping the sweetness and spice typical of the category.
As a bourbon, it is generally built around a corn-forward mash bill and matured in new charred oak barrels, which commonly brings notes in the vanilla, caramel, and baking spice range. The moderate bottling strength should offer a bit more intensity and texture than standard 40% releases without being overly aggressive.
