Hand Barrel Double Oak is a bourbon, a whiskey style made primarily from corn and typically known for a sweeter profile than many other whiskies. For someone new to whisky, bourbon often shows approachable notes like vanilla, caramel, and oak.
The term "double oak" generally suggests additional influence from oak, which can bring more wood spice, toast, and richness to the whiskey. That style often appeals to drinkers who enjoy a fuller, more oak-forward bourbon experience.
