An infinity bottle, also referred to as a "solera", "fractional", or "living" bottle, is your own personal blend of whiskeys that is ever changing. By simply combining a bit of your favorite whiskeys in an empty bottle (or by adding to a base whiskey) you get a personal, never-ending blend of your own creation. This blend will likely have never been possessed or enjoyed by anyone else, ever. As you continue to add more, the flavor profile of the bottle is always new, evolving, and taking on a life of its own.
