Driftless Glen Small Batch Bourbon is a straight bourbon whiskey bottled at 48% ABV and presented with a stated age of 4 years. For a novice drinker, that usually means a fuller, more assertive style than lower-proof bourbon, while still staying approachable.
As a young bourbon matured in new oak, expect a profile built around corn sweetness, vanilla, caramel, and oak spice. The age suggests a lively character rather than deep old maturity, with the cask influence playing a clear role in the overall balance.
