This kit pairs two glass steeping bottles with a dozen vials of wood chips and botanicals, so you can flavor and rapidly “age” an ordinary bottle of spirit in about three days instead of years in a barrel. Each vial pushes the base whiskey a different direction — smoke, oak, spice — which makes it a tasting experiment more than a one-shot recipe. It’s a hands-on gift for the person who likes making the thing as much as drinking it.
