Abstract: A bottle identification topper is a flexible cap that can fit over the top of an existing bottle cap. The identification toppers may have different indicia, either imprinted thereupon, or attached thereto, to clearly identify a bottle, such as a beverage bottle, by its top. The bottle identification toppers may be provided in a box that may, for example, attach to the refrigerator and be readily available for users. The user can simply take one of the toppers, note the indicia it contains, attach the topper to the bottle cap, and they now know that this bottle belongs to them. The result is a simple, easy to use and fun bottle identification system.
